The home team should ensure that the American flag is in good condition. It should be pointed out to players and coaches that we continue to be judged by the public in this area of respect for the flag and our country. Failure to be on the field by the start of the National Anthem may result in discipline, such as fines, suspensions, and/or the forfeiture of draft choice(s) for violations of the above, including first offenses.”

Excerpt:

Volcano Watch: Heavy Breathing in Santorini

4/25/12

The earthquakes and ground deformation scientists observed between 2011 and early 2012 are unprecedented since the 1950 eruption. But just because a volcano is sucking in breath doesn’t mean it will spew. Iceland’s Eyjafjallajökull stratovolcano really let loose in 2010 after its own swarm of deformation-driven tremors, but Long Valley caldera in California has been breathing heavily since 1980 with no eruption at all.

So, what’s in store for Santorini?

In a recent analysis of the volcano published in Geophysical Research Letters, scientists estimate Santorini's latest inflation is due to 14.1 million cubic meters of magma accumulating in a chamber about 4.5 kilometers below the surface.

That may sound like a scary-big mass of melted rock, but it represents only about 0.03 percent of the estimated eruptive volume from the monstrous 1650 B.C. eruption—not nearly enough for a repeat performance. Should Santorini erupt, it will most likely be a relatively tame event, the study’s authors say.

Still, they do offer one warning: “Potentially more dangerous is the effect of volcanic ashfall and earthquake activity, which could damage houses, induce landslides along the steep caldera cliffs and cause local tsunamis that could be dangerous for the local boat traffic within the caldera.”

Russian Shiveluch volcano spews ash 10.7km above sea level

Published: Thursday, Apr 26, 2012, 18:02 IST
Place: Vladivostok | Agency: ANI

The Shiveluch volcano on Russia's Far Eastern Kamchatka Peninsula on Thursday ejected an ash cloud to as high as nearly 11km above the sea level, the Itar-Tass news agency reported.

An ash column from the volcano rose to a height of 10.7km above the sea level.

There was no immediate threat for the population, and no emissions of volcanic dust were monitored in neighboring villages.

Two earthquakes were registered at the volcano over the past 24 hours, which was given the highest Red Aviation Code.

This was the most powerful eruption of ash registered at Shiveluch this year. Shiveluch has been active for more than four weeks.

Shiveluch, standing 3,283 meters above the sea level, is Kamchatka's northernmost active volcano.

Lava from Puu Oo spreads over coastal plain

By Star-Advertiser staff

POSTED: 03:35 p.m. HST, Apr 25, 2012

Lava flows from Puu Oo vent are spreading over the coastal plain in Kalapana and over the weekend entered the Hawaii Volcanoes National Park. But the flows are still about a half-mile from the ocean.

The Hawaiian Volcano Observatory released new lava photos taken Monday that show slow-moving breakouts of pahoehoe lava, with the characteristic look of bunched up rope as it cools.

Other photos released in the last month show how the lava has been spreading on the plain, rather than moving directly to the south, toward the ocean.

The plain is below the Pulama Pali and the Royal Gardens subdivision.

The observatory also released video and thermal images showing the summit lava lake rising at Halemaumau Crater.

A glow from the lava lake illuminates the gas plume coming from the vent at night. The lava level rises and falls as the volcano goes through inflation and deflation cycles. The lake level is about 230 feet below the floor of Halemaumau Crater.

Ah, the puu oo vent is at it again! Now that is my old stomping grounds. I lived jest a few miles from that vent, to the east of the volcanos park. I actually walked the park one time over night hitchhiking to Kona from Hilo.

You haven't seem stars till you see them from the middle of that park where there is no lights visible for miles. It's stars 360 degrees horizon to horizon. Never seen so many before or since. And saw at least 3-4 "falling stars".

I've been through that one subdivision they mentioned, Royal Gardens. When I was there, it was not much more populated than the one I lived in, Hawaiian Acres, down the street from that one. The lot sizes there are I think 1/4 acres, but where I was, it's 3 acre plots. Did you know that you can get 3 acres of land, in Hawaii, for under $30,000? As cheap, and at times cheaper, than land on the mainland. Of course there is that whole volcano thing!  Wink

Nicaragua Monitors Microseismic Activity Increase in Volcano

Managua, Apr 29 (Prensa Latina) Nicaraguan Experts reported Sunday more seismic activity at Masaya volcano, about 20 kilometers south of Managua, with an increase in expulsions of sulfur gases, which keeps the disaster warning system in high alert.

According to the report, a crack in the main crater causes higher emissions and a sound similar to a jet engine.

Specialists of the National System for Prevention, Mitigation and Attention to Disasters (SINAPRED) and the Nicaraguan Institute of Territorial Studies (INETER), told the press that they detected this unusual behavior several days ago, but for now there is no reason for alarm.

The INETER geophysics director, Angelica Munoz, told the site El 19 Digital they monitor Masayaâ�Ös situation closely because of rising emissions and temperature above the normal range.

Technical teams assess the seismic tremor, but there is no emergency declared and the gates of Masaya Volcano National Park remain open to the public, said the director of INETER, Jorge Castro, and the executive secretary of SINAPRED, Guillermo Gonzalez.

Yellowstone: New Picture Emerges Of A More Active, Less ‘Super’ Volcano

April 30, 2012

New research is casting doubts on the frequency or even the possibility of a ‘super-eruption’ that could blot out the sun from the Earth with a thick veil of volcanic ash.
 
A joint research team from Washington State University and the Scottish Universities Environmental Research Centre said the biggest Yellowstone eruption on record was actually two different eruptions at least 6,000 years apart.
 
According to the study published in the June 2012 issue of the Quaternary Geochronology, these eruptions are thought to have created the Huckleberry Ridge around 2 million years ago.  The first eruption generated 2,200 cubic kilometers of volcanic material, while the second, smaller eruption generated 290 cubic kilometers.
 
The first eruption is still considered to be ‘super’ according to the Volcanic Explosivity Index (VEI) and likely covered the sky in volcanic ash from California to the Mississippi River.
 
The VEI was developed by Chris Newhall of the U.S. Geological Survey (USGS) and Sephen Self at the University of Hawaii in 1982. The open-ended scale ranges from 0 to 8 and is based on the volume of material produced, eruption cloud height, and other qualitative observations. Small continuously erupting volcanoes, like those found in Hawaii, are considered a zero on the VEI. The 1980 Mount St. Helens eruption and the Vesuvius eruption in 79 C.E., both of which produced about 1 cubic km of volcanic material, rank in the middle of the pack at five on the VEI.
 
The recent study’s findings suggest that the volcanic formation known as the Island Park Caldera is more active than previously thought and could help geologists to more accurately predict its next seismic event. The caldera is actually comprised of two smaller calderas and stretches 58 miles from Wyoming to Idaho.
 
“The Yellowstone volcano’s previous behavior is the best guide of what it will do in the future,” said study co-author Ben Ellis of Washington State University. “This research suggests explosive volcanism from Yellowstone is more frequent than previously thought.”
 
In calculating the different layers of rock and sediment, the team honed radioactive dating techniques involving the potassium 40 and argon 40 isotopes. These radioactive elements act as a “rock clock” for dating samples and have a precision of 0.2 percent. Darren Mark, study co-author at the Scottish research center, recently helped fine tune the technique to improve it by 1.2 percent—an exponential improvement in accuracy.
 
“Improved precision for greater temporal resolution is not just about adding another decimal place to a number, says Mark. ”It’s far more exciting. It’s like getting a sharper lens on a camera. It allows us to see the world more clearly.”
 
While the last known Yellowstone eruption to cause a lava flow was about 70,000 years ago, smaller steam-only eruptions have caused seismic events like the one at Yellowstone Lake almost 14,000 years ago that created a 5 km crater.
 
The Old Faithful geyser is probably the most famous evidence of ongoing volcanic activity at Yellowstone Park.  The geyser erupts between every 65 and 91 minutes, depending of the duration of the previous eruption.

Mt Lokon erupts again

The Jakarta Post, Jakarta | Tue, 05/01/2012 1:05 PM

Mount Lokon volcano in North Sulawesi erupted again at 11:55 a.m. local time on Tuesday.

The latest eruption was larger in magnitude compared to the eruption last Wednesday but local residents were more prepared.

The eruption was preceded by a number of mild earthquakes over a span of two minutes.

National Disaster Mitigation Agency (BNPB) spokesman Sutopo Purwo Nugroho said smoke plumes reached 2,500 meters in height when Mount Lokon erupted.

According to geologists with the Volcanology and Geological Disaster Mitigation Center (PVMBG), it is not time for residents to evacuate yet, but evacuation sites are being prepared just in case.

The BNPB has deployed a team to keep the situation in Mount Lokon under control. The agency has also prepared transport, Rp 400 million (US$43,600) in cash and other equipment.

Other emergency teams are on stand-by in Malang’s Abdul Rahman Saleh Airport with Hercules C-130 aircraft ready for evacuation. “Everything is ready,” Sutopo said. (nat/swd)

http://www.thejakartapost.com/news/2012/05/01/mt-merapi-enters-preparation-phase-eruption-expert.html

5/1/12

Mt Merapi enters preparation phase before eruption: Expert

The Mt. Merapi volcano restarted its inflation process immediately after the 2010 eruption and has entered its preparation stage of a forthcoming eruption, a Japanese researcher has said.

Masako Iguchi, a researcher from the Disaster Prevention Research Institute at Kyoto University, said Tuesday that the global positioning system (GPS) installed on three Indonesian volcanoes, namely Guntur, Sinabung and Merapi, to detect their ground deformations, had signaled the inflation of Mt. Merapi.

Before the 2010 eruption, he said, Merapi had erupted in 2001 and 2006. This showed that there were some periods in which the volcano had no deformation until it inflated and the next eruption occurred on Oct. 26, 2010.

“But in this latest case, we detected that after its 2010 eruption, Merapi inflated again very quickly. This means that Merapi is a very active volcano,” Iguchi said during a meeting to present the team’s project report titled “Multi-Disciplinary Hazard Reduction from Earthquakes and Volcanoes in Indonesia”.

5 Volcanoes You Should Keep Your Eye On
By OurAmazingPlanet Staff | LiveScience.com – 59 mins ago.

Italy's Mount Etna and Mexico's Popocatépetl volcano have been huffing and puffing their way into the news recently, spewing plumes of ash and dribbling lava in the latest flare-ups of eruptive activity that have been going on for years in the case of both volcanoes.
 
While larger eruptions, such as Indonesia's Pinatubo in 1991 and the 1980 blast of Mount St. Helens in Washington, are more famous for the disruptions they caused, some near-constant eruptions have their own associated hazard, posing threats to nearby communities and potential disruptions to air traffic from ash plumes.
 
Here are five volcanoes that don't always get a lot of fanfare, but have been quietly (or maybe not so quietly) rumbling and spitting up volcanic material continuously for years — even decades — in order of the number of years they've been erupting.
 
5. Sangay in Ecuador – 94 years
 
The modern volcano structure, which reaches a height of 17,158 feet (5,230 meters), dates back about 14,000 years and was built within horseshoe-shaped calderas, or volcanic depressions, of two previous edifices that collapsed and cause avalanches. The earliest report of a historical eruption here was in 1628; then more or less continuous eruptions were reported from 1728 until 1916. The volcano started up again in 1934 and hasn't stopped since.
 
4. Santa María, Guatemala – 101 years
 
Santa María is a 12,375-foot (3,772-meter) tall stratovolcano that towers over Guatemala's Pacific coastal plain. It erupted catastrophically in 1902, one of the largest eruptions of the 20th century, causing severe damage throughout southwestern Guatemala and carving a crater on the volcano's flank. A lava-dome complex, calledSantiaguito, has been forming in the crater since 1922.
 


3. Stromboli, Italy - 108 years
 
Stromboli is the tip of a massive underwater volcano that has been erupting nearly continuously for more than2,000 years. The explosive style of eruption displayed by it and other volcanoes is known as "Strombolian. A 2002 eruption caused a small tsunami and damaged a village on the island, which lies off the coasts of Italy and Sicily.
 
2. Mount Etna, Italy - 109 years
 
Dating back to 1500 B.C., the volcano has erupted around 200 times. The mountain is currently around 10,958 feet (3,340 m) high and is the largest active volcano in Europe. The most violent eruption in the history of Mount Etna occurred in March of 1669. The volcano spewed molten rock for days on end, the eruption finally stopped at the end of April that year.
 
1. Mount Yasur, Vanautu - 111 years
 
This stratovolcano is part of the archipelago nation of Vanuatu in the South Pacific.Yasur has been erupting nearly continuously for over a century, and its eruptions, which often occur several times an hour, are classified as Strombolian or Vulcanian (a relatively low-level type of eruption).

http://news.discovery.com/earth/satellite-spies-hot-sandwich-120502.html



May 2, 2012 -- A plume of volcanic smoke is seen rising from the appropriately-named Mount Asphyxia volcano, located on Zavodovski Island in the southern Atlantic. The image was acquired on April 27 by NASA's Aqua satellite.

Zavodovski is part of the South Sandwich Islands, a group of 11 British-owned islands located 217 miles southeast of South Georgia, off the tip of South America. Only 3.1 miles wide, the icy island is dominated by the 1,800-foot-high stratovolcano.

Aptly named, the sulphuric fumes from Asphyxia coupled with the stench of penguin droppings -- the island is a breeding ground for millions of chinstrap penguins -- can be suffocating for human visitors.

The plume is seen here snaking into upper-level winds where it takes a turn to the northwest. The other islands exhibit swirling cloud vortices on their lee sides, created by their disturbance of prevailing winds.

During the month of April 2012, the University of Utah reports 29 earthquakes were located in the Yellowstone National Park region. The largest was a magnitude 2.4 event on April 2 at 6:27 PM MDT, located about 5 miles north northwest of West Yellowstone, MT No earthquake swarms were detected in April. Yellowstone earthquake activity continues at relatively low background levels. Slow subsidence of the caldera, which began in early 2010, continues. Current deformation patterns at Yellowstone are well within historical norms. Please see: http://www.uusatrg.utah.edu/ts_ysrp.html for ...

Mt. Baekdu eruption's impact on NE Asia (25)

Mt. Baekdu has been carefully observed since 1999 when a volcanic observatory was built in China, and since 2002, there have been some symptoms of an eruption.
 
By Park Chang-seok
 
Yes, one! There’s only one thing about which they think in a same way – a concern about possible eruption of Mt. Baekdu. The two Koreas remain at odds in everything. But they are one in voicing how to counter the possible volcanic explosion of the highest mountain in the Korean Peninsula
 
Inter-Korean anxiety is mounting, with growing apocalyptic predictions on the dormant volcano. A South Korean geological expert has warned that the volcano could erupt sometime around 2014 and 2015.

Former North Korean leader Kim Jong-il reportedly said people in some regions of Yanggang and North Hamgyeong Provinces were feeling anxiety over a volcanic eruption of Mt. Baekdu. Kim called for quick countermeasures by the North Korean authorities.
 
If a volcano, located on the border between North Korea and China erupts, damage could be 10 to 100 times greater than that caused by the April 2010 eruptions in Iceland. Experts predict that the ashes would not only hit the neighboring area but damage agriculture and cause serious disruptions in industrial activities and air flights. The Korean Peninsula, China, Japan and Russia would be severely damaged.
 
A volcanic eruption begins when pressure on a magma chamber forces magma up through the conduit and out the volcano’s vents. When the magma chamber is completely filled, the type of eruption partly depends on the amount of gas and silica in the magma. The amount of silica determines how sticky (level of viscosity) the magma is and water provides the explosive potential of steam.
 
The 2010 Iceland eruption caused enormous disruption to air travel across Western and Northern Europe, although relatively small in size for volcanic eruptions. About 20 countries closed their airspace and it affected hundreds of thousands of travelers. A very high proportion of flights within, to, and from Europe were cancelled, creating the highest level of air travel disruption since the World War II.

The surprising threat from Mexico's awakened volcano

Geologists warn that powerful mudflows spawned by Popocatepetl could wreak havoc

5/3/12

North America's second-tallest volcano recently rumbled to life, putting authorities on edge. Big eruptions of Mexico's massive Popocatepetl volcano are "few and far between," as one geologist says. Yet even without any dramatic fireworks, 17,800-foot (5,425-meter) "Popo" has the power to wreak havoc.

Geologist Mike Sheridan, a professor emeritus at the University at Buffalo, said that Popo and, in fact, many other volcanoes around the world harbor a means of destruction that many people may not associate with volcanoes: mudflows. 

"And they don't even require an eruption, so they are less predictable," Sheridan told OurAmazingPlanet.

Popocatepetl lies about 40 miles (70 kilometers) southeast of Mexico City. The mountain reawakened in December 1994 after five decades of silence. Yet in the nearly 20 years since, the volcano has rarely exhibited the kind of vigorous activity that began the week of April 12.

Debris from volcano closes Mexico airport
by Staff Writers
Puebla, Mexico (AFP) May 9, 2012

Ashes from Mexico's Popocatepetl volcano forced officials to close the airport in nearby Puebla for some 14 hours, to allow for cleanup after it spewed out heaps of ash and rock.

The Puebla International Airport was able to reopen Wednesday after dozens of workers cleared its runways of volcanic ash that posed a risk to departing and arriving aircraft, said officials.

The airport's closing caused just one cancellation, a flight to Houston, Texas early Wednesday, said Puebla's civil protection director Jesus Morales.

Since Popocatepetl came to life several weeks ago, it has spewed gas and glowing rock as much as one mile (1.6 kilometers) beyond its crater, and has intermittently belched out water vapor and ash.

Officials in this central Mexican state have prepared temporary shelters as a precaution and locals were wearing face masks to protect their lungs from ashes in a populous area around the volcano.

The city of Puebla lies in the shadow of the volcano about 55 kilometers (35 miles) from the federal capital Mexico City.

The country's second highest peak, Popocatepetl, means "smoking mountain" in the indigenous Nahuatl language.

After moderate activity during most of the 20th century, the mountain registered intense rumblings beginning in 1994, with the strongest coming in December 2000, when nearby communities were evacuated.

That thing is less than 50 miles from Mexico City? Oooh, that's not good. Though I really don't want to see it happen, I have a feeling in all the end times there will be a volcano REALLY go off, if not more than one. Each wouldn't devistate the whole planet, but one or two here and there will make things really bad for "diverse places" hit.

Active fault may lie directly beneath Mount Fuji: researchers

Kyodo

 
An active fault as long as 30 km may lie directly beneath Mount Fuji, a team of researchers has said in a recent survey report.

The possible fault was detected through a simulated earthquake conducted during a crustal survey over a distance of around 34 km from Fujiyoshida in Yamanashi Prefecture to Susono in Shizuoka Prefecture, said Hiroshi Sato, professor at the Earthquake Research Institute at the University of Tokyo.

"More studies are needed to determine the depth and other details of the fault," Sato added.

While faults have been confirmed around Mount Fuji, little is known about the seismic structure beneath Japan's highest mountain due to mudflows caused by a huge landslide that occurred around 2,600 to 2,900 years ago, as well as thick layers of volcanic ash.

Satellite spots Pacific volcano activity
Published: May 10, 2012 at 6:01 PM

GREENBELT, Md., May 10 (UPI) -- A NASA satellite has captured a dramatic image of steam and gas plumes from a volcano in the Mariana Islands in the Pacific Ocean, U.S. scientists said.
 
The image shows the activity on Pagan Island, the largest and one of the most active of the Marianas volcanoes, a NASA release reported Thursday.
 
Fires and smoke on the island was imaged on Tuesday by the Moderate Resolution Imaging Spectroradiometer instrument aboard NASA's Terra satellite.
 
Pagan Island consists of two volcanoes connected by a narrow isthmus, and almost all of the historical eruptions of Pagan dating back to the 17th century have originated from North Pagan volcano.
 
The largest eruption of Pagan during historical time took place in 1981 and prompted the evacuation of the sparsely populated island, NASA aid.
 
The Marianas are an arc-shaped archipelago consisting of the summits of fifteen volcanic mountains, anchored at its south end by the island of Guam.

Mexico volcano spews huge ash cloud, frightens villager

5/12/12

SANTIAGO XALITZINTLA, Mexico (Reuters) - Mexico's Popocatepetl volcano spewed out huge clouds of ash and fiery rock overnight, closing a local airport on Saturday and frightening nearby villagers, already on edge after weeks of increased activity.
 
Popocatepetl, 50 miles southeast of Mexico City, shook with tremors that belched out four large plumes of ash on Friday night and Saturday morning, the National Center for Disaster Prevention said in a statement on Saturday.
 
The biggest expulsion shot an ash cloud 2.5 miles into the air and launched glowing rocks more than half a mile from the crater, the statement said.
 
Raul Arambula, a scientist collaborating with the government's disaster center, said the volcano threw out the most ash and fragments of red-hot rock since authorities raised the alert level last month.
 
"It was spectacular," Arambula said. "Of course, it makes you worry about everyone living nearby."
 
In Santiago Xalitzintla, a village about 6 miles from the volcano, the loud rumblings sent residents running to the town square during the night.
 
"The volcano is looking serious. It was really roaring strongly last night," said Juan Castro, 83, who said he was half-deaf but had no trouble hearing the tremors.
 
The ash clouds forced the airport in the central state of Puebla to suspend operations on Saturday. Billowing ash earlier in the week closed the airport on Tuesday and Thursday.
 
Civil protection officials in Mexico City said a change in wind patterns could send ash over the capital next week.
 
Mexico's disaster center raised the volcano's alert level to yellow phase three from yellow phase two in mid-April, the third-highest warning on the center's seven-step scale. There are no plans yet to evacuate nearby residents.
 
"They told us that we need to be ready because if we have to evacuate, they are going to warn us with the church bells," said Lizbeth Agustin, a 22-year-old candy vendor who had collected half a pail of ash in the town center of Santiago Xalitzintla.
 
Popocatepetl has spewed smoke and ash sporadically over the past few years. A major eruption in 2000 forced the evacuation of nearly 50,000 residents in three states surrounding the peak.

Mount Fuji Collapse Possible After New Fault Discovered
May 11, 2012  A recently finished three-year study from Japan has discovered a new fault line running beneath Mount Fuji, which towers over 12,000 feet above sea level.
Analysis done on the fault line by the University of Tokyo shows the potential for a magnitude 7.0 quake, which could result in a collapse of part of the national landmark and tourist attraction.

Director for earthquake investigation at the science ministry, Yasuhiro Yoshida said "It's possible that the mountain could collapse with mudslides flowing to Gotemba," a city near the base of the mountain.
Further analysis will be done to determine the full effects of an earthquake on the mountain, such as a possible eruption or devastating landslides.

Respiratory Diseases and Infections due to Mexican Volcano's Activity

Mexico, May 16 (Prensa Latina) Acute respiratory infections increased by three percent among the inhabitants of the southeastern area of the State of Mexico, who are exposed to ash thrown by the Popocatepetl volcano, said the Ministry of Health.

The head of the Department of Epidemiological Surveillance of the Mexico State Health Institute, Hector Resendiz, said the increase in these diseases has occurred in children under eight years old and adults over 60.

According to the state agency, residents of Amecameca, Ozumba, Tepetlixpa, Ecatzingo and Atlautla are those who mostly received medical attention after April 21 when volcanic dust began to fall in those municipalities that are closest to Popocatépetl on the Mexico State's side.

Resendiz added that cases of conjunctivitis have also risen, "so far we have counted 348 cases of people who have been in contact with volcanic dust".

On Tuesday, the National Center for Disaster Prevention reported the new increased activity of the volcano, which now is on yellow alert phase three.

High lava level reported at Kilauea volcano summit

May 16, 2012

http://www.bigislandvideonews.com/2012/05/16/high-lava-level-reported-at-kilauea-volcano-summit/

HAWAII VOLCANOES NATIONAL PARK, Hawaii: Scientists with the USGS Hawaiian Volcano Observatory are reporting a  relatively high lava lake level at the Halema`uma`u crater vent over the past two days, following a summit inflation at Kilauea.
 
Quote
According to Tuesday’s Kilauea activity report:
 

The summit tiltmeter network recorded another DI deflation around 5 pm last night when the lava lake level started to drop; a laser rangefinder measurement yesterday placed the lava lake surface about 67 m (220 ft) below the Halema`uma`u Crater floor – a pretty high level.

The lava has been close to the level of the deep inner ledge. A photo released by HVO (above) shows continuous spattering at the southern lake margin tossing spatter onto the crusted lake surface as well as onto the rim of the ledge, building a steep spatter rampart (left side of image).

Blasts Continue to Menace People Near Mexican Volcano

5/18/12

Fresh blasts from Mexico’s Popocatepetl volcano spewed fiery rock and caustic ash over residents around the Mexico City suburb of Puebla, already on edge after weeks of ongoing eruption.
 
Ash soared 2.5 miles into the sky during early Saturday’s explosion, forcing a local airport to close.

Residents of the nearby village of Santiago Xalitzintla rushed into the town square during the middle of the night as terrifying rumblings and blasts caused buildings to shudder.
 
Last week residents in eastern parts of Mexico City were provided with face masks to protect them against ash raining over the region from Popocatepetl’s blasts.

Prevailing winds have so far spared the capital district from significant ash falls.

Popocatepetl has become increasingly active during 2012.

A major eruption in 2000 forced 50,000 people to evacuate in three states that surround the towering mountain.

Satellite Spies New Lava Flow on Active Volcano

5/18/12

Bagana volcano is one of the most active in Papua New Guinea, but it is remote, and so poorly monitored.
 
Located on the mountainous spine of Bougainville Island, it is both far from any cities or large towns and is hard to reach due to the rough terrain around it. Satellites are the best way for volcanologists to keep an eye on the active peak, which has an elevation of 5,741 feet (1,750 meters).
 
The volcano emits gases (including water vapor and sulfur dioxide) almost continuously, and frequently spits up thick lava flows.

Mount Marapi Volcano Erupts Again

5/19/12

A report, published in the Journal of Volcanology and Geothermal Research, has unveiled recently that a volcano, namely Indonesia's Mount Marapi, erupted early Friday at 7:15 a. m. local time, lasting for nearly ten minutes.
 
It has been found that the volcano has had several such eruptions since when its alert status was updated last August. Also, the same has erupted for a total of around 454 times since the late eighteenth century till 2008.
 
While a majority of these were minor eruptions, fifty of them were significant, last in the year 2005, found the team of researchers from Oregon State University.
 
The erupted volcano is located in the province of West Sumatra, near the cities and town of Bukittinggi, Padang Panjang and Batusangkar in West Sumatra. As per the findings, the volcano is the most active one.
 
It is being said that its eruptions had killed 300 people between October and November and had caused around 300,000 people to relocate as well. "Our study found some of the first evidence that the region has a much more explosive history than perhaps has been appreciated", said Morgan Salisbury, lead author.

Guatemala volcano spits lava and ash

May 19 (Reuters) - Guatemala's Fuego volcano belched burning lava and black ash into the sky early Saturday, leading the government to issue an airplane advisory and close sections of highway.

The volcano, about 25 miles (40 kilometers) southwest of the capital, erupted about 2:45 a.m. (0745 GMT), spewing a column of ash up to 16,400 feet (5,000 meters) above the crater and launching burning red lava nearly 1,300 feet (400 meters) high.

The national emergency commission issued an advisory, warning planes not to fly within a 25-mile (40 kilometer) radius of the volcano. The La Aurora international airport in Guatemala City remained open.

The commission also closed two stretches of highway threatened by lava flows that reached the base of the mountain.
