Increased Seismic Activity in Iceland’s Katla Volcano

Increased seismic activity was detected in Mýrdalsjökull glacier in south Iceland, under which the volcano Katla lies, last night. Twenty-six minor earthquakes were picked up by sensors, all of which had their epicenter within the Katla crater.

El Hierro volcano (Canary Islands): continuing earthquakes, volcanic tremor and eruption warning
 
Tuesday Jun 26, 2012 19:27 PM | Age: 3 hrs
 
BY: T

While the unusually strong earthquake swarm under El Hierro Island continues, harmonic volcanic tremor has reappeared short time ago at about 16h10 UTC.

 The tremor, a low-frequency ground vibration, is thought to be caused by moving magma. It had been strong yesterday and correlated well with a southward propagation of earthquake locations, suggesting that magma at about 20 km depth flew from underneath the El Golfo area towards the EL Julan (south) coast, in a similar way as before the Oct 2011 eruption, but became blocked there, and did not reach the southern rift zone near La Restinga.

 After the cease of tremor in the afternoon, earthquakes still continued at high rate, marking a record figure with over 180 quakes larger than M2 yesterday alone, and more than 150 quakes larger than M1.5 so far today.

 In other words, pressure continued to cause wide-spread rock fracturing underground and cause small intrusions of fluids. Now, the re-appearance of tremor could mean that magma is moving again somewhere underneath the island. Where to and whether or not it might reach the surface and initiate a new eruption is difficult to know at the moment. It is essential to continue to monitor location and magnitude of earthquakes.

Stromboli volcano (Italy): moderately strong activity

Our colleague Marc Szlegat just returned from a visit to Stromboli volcano whose activity has recently been increasing. Marc observed that there were 5 active glowing vents within the crater terrace. The most spectacular explosions took place from the eastern vent, the cone that had been building since 2009. They occurred roughly every 20 minutes, with sometime powerful explosions ejecting lava bombs up to 300 m height, many of which falling onto the Sciara del Fuoco.

Frequent eruptions also occurred from the western vent, with typical ejection heights of 50-100 m, and occasionally up to about 200 m. A third vent in the central crater and rarely a vent at the extreme western end of the crater erupted occasionally as well.

Colombia volcano erupts, prompts evacuations

BOGOTA (Reuters) - Colombia evacuated people from communities close to the Nevado del Ruiz volcano after an eruption on Saturday that spewed smoke and ash from its crater, bringing back memories of avalanches that in 1985 buried tens of thousands under rocks.
 
President Juan Manuel Santos said on his Twitter account that the area around the Nevado del Ruiz, in the central spine of Colombia's Andean mountain range, had been put on red alert and people should leave the area.
 
Even as volcanic activity began to subside, emergency services urged 4,800 residents in Caldas and nearby Tolima province to get to safety, according to Carlos Ivan Marquez, who heads the security effort. The volcano is about 110 miles west of the capital Bogota.
 
"It's fundamental that communities near to the volcano follow all security recommendations; that means preventative evacuations and that people remain calm," Marquez said.

Volcanic activity lifts Canary island

 Shocked

Following days of almost continual earthquakes, residents of the small Canary island of El Hierro are once again living in fear of a volcanic eruption as their island begins to lift.



According to the National Geographic Institute of Spain, increases in seismic activity on the island has seen literally hundreds of earthquakes, known as a swarm, shaking the island and gradually increasing in strength since June 25. Around 750 earthquakes have been recorded although few have been strong enough to be felt by the residents until the last two days

The island has been placed on yellow alert by the security committee in charge of operations as the earthquakes increase. The largest so far was registered at 4.0 on the Richter scale on Wednesday June 27.

More frightening for the approximately 10,000 residents is the fact that a bulge has developed in the island, lifting it five centimetres in four days. Whereas the volcanic activity of 2011 was based out at sea, this time the magma appears to be forming right underneath the island and the pressure is building. Scientists on the island are using the position of the earthquake epicentres to try and work out where the magma from the volcano will come to the surface.The longer it takes to find a vent, the more the pressure from the magma will grow and the larger any possible eruption is likely to be.
Earthquake Report says that PEVOLCA (Civil Protection from Volcanic Risk) has said that there is an acceleration in the flow of magma, with a "clear process of inflation".

As reported by Digital Journal on June 25, the island suffered serious seismic activity last year, resulting in an undersea volcanic cone as can be seen in the video. However, over time, the activity died down and it was thought by experts that was the end of the event. The research vessel 'Hesperides' which had been investigating went home and the live cameras were turned off. Now the 'Hesperides' is hurrying back to the island but the cameras have not as yet been turned back on.

The website Decoded Science, in an article by Jennifer Young, explains how magma chambers work and how scientists are processing information from volcanoes to learn more about predicting possible eruptions. It is this activity that the scientists on the 'Hesperides', in conjunction with those on the island itself, will be studying in an effort to try and predict if and when the volcano under El Hierro will erupt.

Official reports have been few and far between and the Spanish media has concentrated rather more on the football and the economy than the volcano growing under one of Spain's most popular holiday destinations, just as the season gets into full swing.

Rumblings under Tongariro

Scientists have raised the Volcano Alert Level at Mt Tongariro after a series of quakes beneath the volcanic complex.

GeoNet said typically Tongariro experienced two such quakes - magnitude 2.5 or less - a year, but there had been more than 20 since July 13.

In a Volcanic Alert Bulletin issued this afternoon, it said the sequence started on July 13 and declined for a period, before restarting on July 18 and increasing in number yesterday.

‘‘These indicate unrest at Tongariro and give reason to change the Volcanic Alert Level to level 1 [from 0] and the aviation colour code to yellow [from green].’’

7/20/12

Giant quake a record-setter

Even though a magnitude-8.6 undersea earthquake that occurred far west of Sumatra on 11 April caused no damage and triggered no tsunami, it was still a record-setter.

For one thing, it was the largest quake ever measured far from the boundary of a tectonic plate, researchers report online in Science.

Also, the so-called intraplate quake is the largest ever measured for a fault zone for which the two sides of the fault slide horizontally past each other rather than having one side of the fault shoved beneath its neighbour.

The epicentre of the quake was located about 400 kilometres southwest of the magnitude-9.1, tsunami-spawning quake that occurred off the northwestern coast of Sumatra on 26 December 2004.

Over the course of about a minute and a half, this spring's shake ruptured 500km of three separate but related faults, all of which were highly stressed.

A lot of that stress was shifted to the area by the December 2004 quake, the researchers suggest.

The faults unzipped at a relatively slow but steady 2.5km per second, the researchers say, with much of the slippage along the faults taking place more than 25km below the seafloor - a depth that helped contribute to the quake's great magnitude.

Tongariro(New Zealand) volcano alert at new high

A "sudden rise" in volcanic activity at Mt Tongariro has prompted scientists to lift its volcanic alert status for the first time.
 
But local businesses and conservation authorities remain unconcerned as they seek to reassure visitors it is "business as usual" at National Park.
 
GNS Science this afternoon lifted Mt Tongariro's volcanic alert status from level zero to level one, and increased the aviation status from green to yellow.
 
It said a series of more than 20 "small" volcanic earthquakes had been recorded at Tongariro since July 13 - more than the average of two per year according to historic seismic data.

Tongariro volcano (New Zealand): seismic swarm, a possible precursor to new activity
 
Monday Jul 23, 2012 12:05 PM | Age: 1 days
 
BY: T

Tongariro volcano is showing signs of a possible awakening. On 13 July 2012, an increase in small (<M2.5) earthquakes was detected. The quakes were clustered at depths of 2-7 km under the area between Emerald crater and Te Mari crater. More than 20 earthquakes were recorded until 20 July, when the seismic activity peaked and prompted GeoNet to raise the alert level from 0 to 1. Compared to a background average of 2 quakes per year, the swarm is significant and could indicate magma movements. Seismic activity dropped on 21 July with only 1 quake since then, but preliminary measurements show an increase in volcanic gas emission. NZ Scientist started to increase their monitoring at the volcano.

Tongariro erupts, alert level raised

The volcanic alert level for Mt Tongariro has risen from 1 to 2 after the central North Island volcano erupted for the first time in more than a century late last night.

 GNS science is reporting that at approximately 11:50pm on Monday night ash fall began to be reported in the volcano's vicinity - it has since been reported as far east as SH5 near Te Haroto and in Napier.

 GNS duty volcanologist Michael Rosenberg told Radio New Zealand that some people are reported to have left their houses on the southern shores of Lake Rotoaira, though no formal notices of evacuation have been issued so far by Civil Defense.

 He said residents in the area have told GNS of hearing several loud explosions, lightning and plumes of smoke and police have been told by an onlooker that "a new hole in the side of the mountain" had formed.

That could be any number of long quiet volcanos all over the place, and some in high population areas, like say Diamond Head in Waikiki, Hawaii.

‘Super volcano’ could kill millions near site of Pompeii

8/6/12

The eruption of Mount Vesuvius near Naples, Italy, in 79 A.D. killed thousands of Pompeii residents and remains one of the most famous volcanic explosions in history. But scientists say a hidden "super volcano" in the same area has the potential to kill millions.
 
"These areas can give rise to the only eruptions that can have global catastrophic effects comparable to major meteorite impacts," Giuseppe De Natale, head of a project to drill deep under the earth to monitor the molten caldera, told Reuters.
 
A caldera, or cauldron, is formed by collapsed land after a volcanic eruption. It can be just as dangerous as volcanic domes, sending magma and ash shooting into the air. A caldera is located in Campi Flegrei. The regional park, which is named after the Greek word for burning, is a major tourist attraction, and the surrounding area is home to more than 3 million residents.
 
"That is why the Campi Flegrei absolutely must be studied and monitored," De Natale said. "I wouldn't say like others, but much more than the others exactly because of the danger given that millions of people live in the volcano."

8/7/12

Volcanic activity world-wide 7 Aug 2012: Tongariro, Etna, Stromboli, Popocatépetl, volcanoes in Guatemala, Colombia, Ecuador

News have been dominated by Tongariro volcano's first eruption in 115 years (New Zealand). At the moment, the volcano is quiet, but eruptions could resume any time.
 
Etna (Italy): Strombolian activity continues at varying levels. Following a phase of weak activity during 4-6 Aug, an increase of activity was observed at the Bocca Nuova during the night 6-7 Aug.
 Also in Italy, the activity at Stromboli (Eolian Islands) has been at relatively high levels over the past days. The number and size of explosions from the summit vents has increased.
 
Popocatépetl in Mexico: About 1 explosion occurs per hour, and strong glow is visible at night. A relatively powerful eruption late on 6 Aug sent ash to up to 30,000 ft (10 km) altitude.
 
The volcanoes in Guatemala have shown little changes in activity over the past days.
 Fuego volcano has intermittent weak strombolian explosions throwing lava up to 100 m above the crater, and the lava flow on the south flank is still active.
 Santiaguito / Santa Maria (Guatemala): Weak to moderate explosions occur regularly and produce ash plumes up to 900 meters high. Avalanches of lava blocks descend on the south flank of the dome.
 Lots of seismic activity is visible on the seismograms, most of it related to rockfalls.
 Some tremor and shallow volcanic quakes and weak degassing are the only signs of activity reported from Pacaya.
 
In Colombia, there are currently 1 volcanoes on orange alert (Ruiz)(eruption warning) and 4 on yellow (unrest):
 Nevado del Ruiz (Colombia) shows tremor, associated with gas and minor ash emissions at low level. A shallow M1.2 earthquake occurred at 3:11 (local time) near the Arenas crater. INGEOMINAS keeps a close watch of the volcano.
 Compared to the previous week, the seismicity at Galeras has increased and shows events related to fluid movements within the volcano. Few weak earthquakes with magnitudes less than 1.1 related to fracturing of rock occurred at shallow depths (less than 4 km) at various locations under the volcano.
 Seismicity at Cerro Machin volcano remains at slightly elevated levels with some weak earthquakes SE under the lava dome at depths between 3.5 and 5 km.
 At Cumbal volcano, seismicity is still above background levels, but has has decreased. Signals are interpreted as fluid movements under the volcano.
 Nevado del Huila The volcano shows normal seismic activity and degassing at low levels with no significant changes to previous weeks. INGEOMINAS keeps the alert level at yellow.
 
Ecuador:
Tungurahua volcano: Activity remains generally at relatively low levels. Few small to moderate explosions (about 3-5 per day) and weak steam and ash venting continue at Tungurahua. The last reported ash cloud altitude was at 18,000 ft (4.5 km) from an explosion on 6 Aug.
 This morning, a more intense phase with volcanic tremor is visible on the seismograms.
 Reventador volcano: IG reports a strong steam plume rising 1500 m above the summit, but does no more mention any active lava flow.
 Sangay volcano: No recent reports of eruptions from remote Sangay are available, but this might simply incidate that its typical strombolian eruptions are too small.

Sotará volcano (Colombia): increase in seismic activity triggers raise in alert level

8/9/12

The recent increase in seismic activity under Sotarà volcano promted INGEOMINAS to raise the alert level from yellow (unrest) to orange (eruption warning) yesterday afternoon.
 
The increase had been detected on June 24, 2012 and since that date, 6891 earthquakes have been recorded, i.e. an average of 150 quakes per day. Most of them (5177) are of very small magnitude, but the remaining 1714 quakes were of significant energy (local magnitudes 0.1-2.2) and concentrated in an area between 0.1 and 5 km northeast of the volcanic summit at depths between 2 and 6 km.

None of these events were felt by inhabitants of the communities surrounding the volcano Sotará.

The deformation network shows a possible inflation process towards the northeast sector of the volcano, which correlates with the epicentral zone of seismicity reported and suggest that magma is rising there, and might (or might not) lead to an eruption in a near to medium future.
 During the month of July geochemical surveys showed no significant changes in temperatures of hot springs in the area.
 
INGEOMINAS stresses that this activity does not pose any immediate danger to the communities aroud the volcano. However, it should be said as well that this could change quickly.

Lightning seen around erupting White Island(New Zealand)
 
Published: 4:21PM Thursday August 09, 2012

Flashes of lightning have been reported coming from White Island as the volcano continues to erupt since Sunday.
 
White Island, which lies 48 kilometres off the Bay of Plenty coast, was raised to a Volcanic Alert Level 2 after a surveillance camera captured a small eruption from its crater last week.

Whakatane Police said they received a number of calls reporting lightning of different colours since just after 7pm.
 
GNS visited the island, which is New Zealand's most active cone volcano, this morning and confirmed it was still erupting with a 300 metre plume of ash spewing from the crater.
 
GNS scientist Michael Rosenberg said volcanic lightning is quite common and is a result of ash generating static electricity.

Sulphur smell across lower North Island, New Zealand
Paloma Migone
stuff.co.nz
Wed, 15 Aug 2012 13:40 CDT

The smell of sulphur from Mt Tongariro has crept back to the lower North Island, with some residents complaining about irritation to their skin and eyes.
 
The smell has become common since the volcano erupted at 11.50pm on August 6 with residents as far as Blenheim noticing it.
 
The Horizon Regional Council today received "multiple complaints" about the smell being back and some residents said the sulphur had become an irritant.
 
Council emergency manager Shane Bayley said the smell was the result of wind drift from the mountain and was not a cause for concern.
 
"Our air quality monitoring sites in Taumarunui and Taihape are not showing any elevated presence of fine air particles.

"However, our team will be keeping an eye on the situation and will alert the public if this situation changes."
 
If the sulphur was affecting people's respiratory system, eyes or skin, MidCentral Health recommended people stay indoors with all the doors and windows closed, a council spokeswoman said.

http://dsc.discovery.com/earth/slideshows/tanzania-volcano/ol-doinyo-lengai.html

Planet Earth is riddled with unmonitored volcanoes. Many could erupt with scant notice to the world, causing anything from minor inconveniences to famines or catastrophic death and destruction. Yet when they blow up, these little-known volcanoes don't usually make headlines for two reasons: 1) The people affected by the eruptions are poor, few in number and tend to be ignored by the world at large, and 2) the remote locations of the volcanoes and lack of monitoring equipoment make details of eruptions scarce.

One very unusual example of such a volcano is Ol Doinyo Lengai of Tanzania. The name means "Mountain of God." After spending the previous four decades in relative rest, the mountain erupted violently in late 2007 and continued erupting through early 2008 with the coldest lava on Earth. Still, it's lava and it made life pretty difficult when the ash and rocks rained down on nearby Masai villages like Naiyobi, seen in this image. The villages were evacuated for a while. When people returned they found their water fouled and many grazing lands unusable -- a hard blow for people who depend on their cattle for their living.

In Jan. 2009, U.S. Geological Survey scientists David Sherrod, Thomas Casadevall and Gari Mayberry answered a call from the government of Tanzania for technical assistance in assessing the danger of Ol Doinyo Lengai. The following are some of their images and reflections from the expedition.

No warning before volcanic eruption

8/23/12

Aucklanders may get only a day or two warning of a volcanic eruption and will know just hours before where it will explode, a scientific paper says.

The 1.4 million people living on the Auckland volcanic field make too much noise for existing instruments to hear what is happening below the surface.

"This means that localisation of a future eruption site is only likely to occur within a few hours or days of an eruption," the paper in the Journal of Remote Sensing of Environment says.

Each new vent in Auckland will occur at a new location, rather than an existing volcano, creating uncertainty over where it will hit.

Volcano activity of August 23-24, 2012 – Mt. Tongariro, Sotara, Shiveluch, Karymsky, Santiaguito, Fuego, Sakurajima, Batu Tara, Tungurahua, Kilauea and Nevado del Ruiz

8/24/12

August , 2012 volcano activity
 
Mount Tongariro volcano (New Zealand) showed some seismicity earlier today (see seismogram below). The activity can only be seen in Oturere and West Tongariro seismograms (close to the Te Maari craters). Below also one of the rara clear view images of Mt. Tongariro with a strongly steaming vent. N report from GNS science about the seismicity however.  The Park service has announced that the trekking trails at Mount Tongariro would be reopened. A 3 km hazard and risk zone will remain in place for some time and might be further reduced once new information of the gas and ash composition is known.

According to INGEOMINAS, the Observatorio Vulcanológico and Sismológico de Popayán reported that during 8-14 August seismic activity at Sotará increased. The seismic network recorded 110 magnitude 0.2-1.6 events mainly located in an area 0.1-5 km NE of the peak, at depths of 2-6 km. Inflation was detected in the NE area, coincident with the zone of increased seismicity. Web-camera views showed no morphological changes. The Alert Level was raised to III (Yellow; “changes in the behavior of volcanic activity”), or the second lowest level. (Smithsonian Institute)
 
KVERT reported moderate seismic activity from Karymsky during 10-20 August. Satellite imagery showed a weak thermal anomaly on the volcano during 10-13, 15, and 18-20 August. The Aviation Color Code remained at Orange.
 
KVERT reported that during 10-18 August weak seismic activity was detected at Shiveluch. Observers noted gas-and-steam activity during 15-17 August; weather conditions prevented observations of the volcano on the other days. Satellite imagery showed a thermal anomaly on the lava dome during 10, 12-13, and 18-19 August. Seismic activity increased to moderate levels and hot avalanches were observed during 19-20 August. The Aviation Color Code remained at Orange.
 
Insivumeh reports 2 moderate explosions at Santiaguito (Santa Maria), Guatemala. The other Guatemala volcano, Fuego sends a white plume approx. 50 meter in the air and grumbles every 1 to 3 minutes. See also seismograms from both volcanoes.

Tangkubanperahu volcano (West Java): increased earthquakes prompt rise of alert level

An increase in seismic activity at Tangkubanperahu volcano near Bandung, the capital of West Java, has been detected since 13 August and promted the Indonesian Volcanological survey (PVMBG) to increase the alert level of the volcano from 1 (normal) to 2 (alert) on 23 August.
 
Between 1 July and 23 Aug, 264 volcanic earthquakes were recorded, which is almost double to values measured during similar periods of time at the beginning of the year. In addition, pulses of volcanic tremor could be recognized.
 Tangkubanperahu has 2 main craters, each about 1000 m wide and 400 m deep, filled by crater lakes, Kawah Ratu (queen) and Kawah Upas, respectively. The craters and lakes along with fumaroles and warm springs are popular tourist destinations. (It is recommended not to climb the volcano's crater, which is a popular tourist destination in the area.
 The last eruptions of the Tangkubanperahu were phreatic explosions in 1994.

Residents, Tourists Warned as Indonesia's Anak Krakatau Activity Increases

Bandarlampung. Volcanic ash from the increasingly active Anak Krakatau has reached a number of areas in Lampung, prompting officials on Monday to issue a warning for local residents and tourists.
 
"The ash was carried by wind from the southeast to the south, reaching Bandarlampung," Nurhuda, who heads the observation and information section of the Meteorology, Climatology and Geophysics Agency (BMKG) in Lampung, said according to state news agency Antara.
 
Nurhuda said the ash fell over several subdistricts in Bandarlampung, about 130 kilometers away from Anak Krakatau.
 
"It is rather unusual for the dust to be this thick," said Juniardi, a resident of Bandarlampung who complained that the falling dust was also hampering visibility.

Nicaragua volcano belches ash cloud, residents evacuated

9/8/12

MANAGUA (Reuters) – Nicaragua’s tallest volcano belched an ash plume up to 2 1/2 miles (4 km) into the atmosphere on Saturday, prompting the evacuation of hundreds of nearby residents who heard eruptions emanating from its crater.

There were no immediate reports of injuries or damage, authorities said.

The 5,725-foot (1,745-meter) San Cristobal volcano, located about 95 miles (150 km) north of the capital Managua in the country’s volcano-dotted northwest, has been active in recent years, and stirred in mid-2008, when it expelled gas and rumbled with a series of small eruptions.

Guatemala Tourist Hub Rocked by Volcano Eruption

Quote
ESCUINTLA, Guatemala –  One of Guatemala's most famous tourist attractions was hit Thursday by a series of eruptions from a long-simmering volcano that sent thick clouds of ash nearly two miles (three kilometers) high, spewed rivers of lava down its flanks and prompted evacuation orders for more than 33,000 people from surrounding communities.
 
Guatemala's head of emergency evacuations, Sergio Cabanas, said the evacuees were ordered to leave some 17 villages around the Volcán del Fuego, which sits about six miles southwest (16 kilometers) from the colonial city of Antigua, home to 45,000 people. The ash was blowing south-southeast and authorities said the tourist center of the country was not currently in danger, although they expected the eruption to last for at least 12 more hours.
 
The agency said the volcano spewed lava nearly 2,000 feet (600 meters) down slopes billowing with ash around Acatenango, a 12,346-foot-high (3,763-meter-high) volcano whose name translates as "Volcano of Fire."

Two Indonesian Volcanoes Awaken, Rattling Nerves


Two of Indonesia’s most active volcanoes erupted on Saturday, prompting the government to issue warnings to populations living near the affected mountains.

The National Disaster Mitigation Agency (BNPB) said on Sunday that new eruption started at Lokon in North Sulawesi and Gamalama at Ternate in North Maluku.

Lokon generated a 1,500-meter high ash plume and violent strombolian (low-level) activity with some lava flow, while Gamalama produced a shower of ashes that covered the nearby city.

Sutopo Purwo Nugroho, a spokesman for BNPB, said on Sunday that Lokon, located in North Sulawesi’s Tomohon area, erupted at 7 p.m. on Saturday.

9/16/12

Volcanic activity world-wide 16 September 2012: Popocatepetl, El Hierro, Fuego, Santiaguito, San Cristobal, Santiaguito, Little Sitkin, Manam, Batu Tara, Sakura-jima

A slight increase of activity can be noted at Popocatépetl volcano in Mexico. The frequency of explosions has increased to more than 1 per hour, i.e. doubled when compared to last week.
 The more energetic explosions produced small ash plumes rising up to 1 km. Episodes of volcanic tremor occurred as well, CENAPRED writes.
 
The new seismic swarm at El Hierro continues with hundreds of small quakes per day concentrated at about 20 km depth in the south-central part of the island near El Pinar. Pulses of tremor and a slight inflation are visible as well, but for now, it seems that magma is not moving much.
 
San Cristobal volcano had a small explosion yesterday at 8:17 am local time. Recent measurements showed an increase of SO2 emissions to 2,490 tons per day, i.e. almost double than before. Also, seismic tremor increased in the evening of 15 Sep.
 
Fuego volcano, Guatemala: Activity remains at normal levels with sporadic weak to moderate explosions with ash rising 400-800 meters and some rumbling sounds. The lava flow to the Taniluya canyon has apparently decreased a lot, as INSIVUMEH reported it to be only 50 m long yesterday.
 
Santiaguito volcano continues to have occasional explosions ejecting ash columns to 500 meters height, which spread west and northwest over the region of the villages of El Rosario and San Marcos, Palajunoj. There is constant activity in the 4 active lava flows, generating avalanches of blocks deposited within the river banks Nima Nima I and II.
 
Most other volcanoes in Central and Southern America have not shown any significantly unusual behavior.
 
Satellite observations:
Batu Tara had its daily explosion to send ash to about 7,000 ft altitude, VAAC Darwin reports.
 
A strong SO2 plume was visible from Manam volcano (PNG) today, suggesting that there is heightened activity or an eruption.
 
Sakurajima volcano seems to be having a break from its relatively strong phase over the past days. There was only one probably weak explosion reported during the past 24 hours.

Volcanic Activity Up in Several Locations
 September 18, 2012

Solo, Central Java. As two volcanos in the eastern part of Indonesia continued to erupt on Monday, Mount Merapi in Central Java has been displaying increasing activity, with rumblings in the past week.

“In the evenings, there are rumblings that are accompanied by the ground shaking,” Sapto, from Samiran village in the district of Boyolali on the slope of Merapi, said on Monday.

He said that the 2,968-meter volcano was also active during the day, as evidenced by the thick column of ash billowing out from its crater.

Sapto said that as of Monday, local authorities had not issued any information to the public regarding the volcano.

Subiso, head of Selo subdistrict in Boyolali, confirmed that no official advisories or warnings had been issued yet about the increased activity on Merapi.

However, he said that the rumbling sounds from the volcano were almost routine in the area, and added that the situation there “is still safe.”

Ngatini, another resident said that the rumblings did not disturb local residents too much.

“If an eruption is imminent, the rumbling will be heard continuously and there will be some ash rain,” she said.

Merapi last erupted in October 2010, spewing enormous amounts of ash. Pyroclastic flows, fast-moving currents of superheated gas and rock, killed more than 300 people along the heavily populated slopes and forced 350,000 to evacuate.

Meanwhile, with a small eruption still taking place on Mount Lokon in Tomohon, North Sulawesi, authorities there are maintaining the alert status for the volcano and have banned all human activities within a 2.5-kilometer radius of the crater.

Farid Sukendar, head of the Lokon volcano observation post, said that  the mountain erupted after dusk on Saturday, spewing superheated volcanic material up to 600 meters and ash up to 1,500 meters into the atmosphere.

“This volcano is active and therefore we should remain vigilant because it could erupt any time,” he said.

Arnold Poli, secretary of the town of Tomohon, located at the base of the mountain, said that the authorities were continuously monitoring the volcano. He said that the series of eruptions had not affected the activities of the local population but added the authorities were calling on everyone to remain alert.

He also said that despite the volcanic activity, the government had yet to evacuate anyone from the villages of Kinilow and Kakaskasen III, the two villages closest to the smoldering crater.

“No one has yet been ordered to evacuate,” he said.

Mount Soputan, in North Sulawesi’s South Minahasa district, and Mount Karangetang in the Sitaro Islands district across from the northernmost tip of Sulawesi remained on a government-ordered standby alert status, or just one rung below the most severe alert.

“There are now three volcanoes in North Sulawesi under the standby alert status,” said Hooke Makarawung, head of the North Sulawesi Disaster Mitigation Office (BPBD).

“People should remain vigilant.”

He said that about 110 people had been evacuated from the slopes of Karangetang and that the North Sulawesi administration had sent relief supplies to them.

Djauhari Kansil, the deputy governor of North Sulawesi, said that those evacuated were from East Siau subdistrict, but he added that in the daytime, the people were allowed to return to their village to work their fields.

They have been asked to return to the shelters in the evening.

The volcanology office also announced on Monday that it had raised the alert level for Mount Gamalama, on Ternate Island in North Maluku province, to standby.

The office, on its website, said that the alert status was raised on Sunday.

The site offered no further details.

The 1,715-meter Gamalama, a conical volcano that dominates Ternate Island, last erupted in December, destroying more than 100 houses and leaving farmers devastated after a thick layer of ash smothered fruit trees and crops.

Four villagers were confirmed dead in that eruption.

Metro TV reported on Monday that the mountain spewed a white column of ash about 500 meters into the atmosphere.

There was also some volcanic debris thrown up by the mountain but on a smaller scale.

It also said the local volcanology authorities had declared a 2.5-kilometer exclusion radius around the crater of the erupting volcano.

On Sunday evening, the smoke and volcanic debris thrown up by Gamalama reached about 1,000 meters into the atmosphere, according to the report.

Anak Krakatau in the Sunda Strait between Java and Sumatra also showed some signs of activity earlier this month. The volcano is the remnant of Krakatau, the site of an earth-shattering eruption in 1883.

China's Changbaishan volcano showing signs of increased activity

9/20/12

Roughly 1,100 years ago, the Changbaishan volcano that lies along the border between northeastern China and North Korea erupted, sending pyroclastic flows dozens of kilometers and blasting a 5-kilometer (3-mile) wide chunk off of the tip of the stratovolcano.

The eruption, known as the Millennium eruption because of its proximity to the turn of the first millennium, was one of the largest volcanic events in the Common Era. In the subsequent period, there have been three smaller eruptions, the most recent of which took place in 1903. Starting in 1999, spurred by signs of resumed activity, scientists established the Changbaishan Volcano Observatory, a network to track changing gas compositions, seismic activity, and ground deformation. Reporting on the data collected over the past 12 years, Xu et al. find that these volcanic indices each leapt during a period of heightened activity from 2002 to 2006. The authors find that during this brief active period, earthquake occurrences increased dramatically. From 1999 to 2002, and from 2006 to 2011, they registered 7 earthquakes per month using 11 seismometers. From 2002 to 2006, this rate increased to 72 earthquakes per month, peaking in November 2003 with 243 events. Further, tracking the source of the earthquakes, the authors tie the bulk of the events to a region located 5 kilometers (3 miles) beneath the volcanic caldera, a source that slowly crept upward throughout the study period, suggestive of an ongoing magmatic intrusion. Gas composition measurements collected from hot springs near the volcano showed spikes in carbon dioxide, hydrogen, helium, and nitrogen gases, which the authors suggest could be related to magmatic outgassing. Ground deformation studies, too, show a brief period of rapid expansion. The authors suggest that though Changbaishan is likely not gearing up for an imminent eruption, one could be expected in the next couple of decades.

Mexican Volcano Popocatépetl Eruptions Increase

Mexico, Sep 25 (Prensa Latina) At least 26 eruptions accompanied by steam and gas, as well as a volcano tectonic quake were registered as a consequence of the Mexican volcano Popocatépetl activity during the last hours, it was reported Tuesday.

 The National Center of Disaster Prevention (Cenapred) said eruptions were of low and medium intensity with no ash expulsion in any of them.

 According to the institution, the volcano tectonic quake was registered at 11.54 local time (16:54 GMT).

 At this moment, the alert light of volcano activity remains yellow phase 2 and the surrounding population to keep informed as to alerts on the activity of the volcano also known as Don Goyo.

 Traffic between Santiago Xalitzintla and San Pedro Nexapa, via the Cortes passage, is under control.

 The Popo is located at the center of the country, in the territorial limits of the Morelos, Puebla and Mexico states.

 Located 55 kilometers Southeast of the Federal District, the Popocatépetl is the second highest volcano in Mexico, with a maximum height of five thousand 458 meters above sea level, only second to the Pico de Orizaba (Veracruz) with five thousand 610 meters.
