Plume Seen Above Kizimen Volcano

Kizimen Volcano on Russia's Kamchatka Peninsula sent a plume toward the west-southwest on January 6, 2010, according to a NASA statement. The Advanced Land Imager (ALI) on NASA's Earth Observing-1 (EO-1) satellite captured this natural-color image the same day.

Low-angled sunlight illuminates the southern face of the plume, leaving the northern side in shadow.

The plume's beige color suggests that its visible components are a mixture of volcanic ash and water vapor. The slopes of Kizimen and the nearby land surfaces appear dull gray-brown, likely resulting from a coating of volcanic ash. (A wider view of the region shows areas father from the volcano blanketed in snowy white.)

Ongoing Eruption of Tungurahua, Ecuador

According to Ecuador's Instituto Geofisico, the Tungurahua volcano was active throughout the last weeks of 2010, with reports of ashfalls on towns near the volcano and explosions that sounded like cannons. Steam and ash plumes were observed rising as high as 36,000 feet (11 kilometers) above sea level.

These two images show Tungurahua as observed by the Advanced Land Imager (ALI) on NASA's Earth Observing-1 (EO-1) satellite on Jan. 1, 2011.

The top view is a natural color image, while the one below is enhanced with shortwave and near-infrared wavelengths. Both show a small plume wafting up from the snow-capped summit through a break in the clouds. The shortwave infrared better discriminates between the plume and clouds, while showing the heat coming from the summit caldera.

2010's World Gone Wild: Quakes, Floods, Blizzards

This was the year the Earth struck back.

Earthquakes, heat waves, floods, volcanoes, super typhoons, blizzards, landslides and droughts killed at least a quarter million people in 2010 - the deadliest year in more than a generation. More people were killed worldwide by natural disasters this year than have been killed in terrorism attacks in the past 40 years combined.

"It just seemed like it was back-to-back and it came in waves," said Craig Fugate, who heads the U.S. Federal Emergency Management Agency. It handled a record number of disasters in 2010.

"The term '100-year event' really lost its meaning this year."

And we have ourselves to blame most of the time, scientists and disaster experts say.


Comment: This article supports the idea of human-caused global warming, and, as the above sentence says, blames us humans for most of the disasters that befell the world this past year. Find an analysis and rebuttal to this story here.


Even though many catastrophes have the ring of random chance, the hand of man made this a particularly deadly, costly, extreme and weird year for everything from wild weather to earthquakes.

Poor construction and development practices conspire to make earthquakes more deadly than they need be. More people live in poverty in vulnerable buildings in crowded cities. That means that when the ground shakes, the river breaches, or the tropical cyclone hits, more people die.

Tungurahua volcano prompts evacuation in Ecuador

The authorities in Ecuador have begun evacuating people from the slopes of the Tungurahua volcano after it started spewing ash.

Scientists say fast-moving currents of extremely hot gas and rock could be seen flowing from the volcano's crater.

Tungurahua, some 135km (85 miles) southeast of the capital, Quito, has been in an active state since 1999.

But experts say there has been a rapid increase in its seismic activity since Saturday morning.

Scientists with the Ecuadorean Institute for Geophysics say the number of explosions has increased. They say the ash cloud has reached 2km (1.2 miles) in height.

People living on the slopes reported the ground and buildings shaking, and a rumbling sound coming from the volcano.

Ecuador Tungurahua volcano re-erupts

The volcano spewed molten rocks and large clouds of gas and ash near Banos, south of Quito, Reuters reported on Tuesday.

The Tungurahua's volcanic activity follows last month's eruption, when a column of gas shot up seven kilometers into the sky.

No casualties have been recorded so far, but flight re-direction is being considered.

Tungurahua is located approximately 150 kilometers southeast of Ecuador's capital, Quito.

After a long period of peaceful resting, the volcano erupted in 1999, leading to the evacuation of about 250,000 people.

In 2006, Tungurahua underwent another major eruption, leading to the death of seven villagers. Yet another major eruption took place in 2008, leading to more evacuations. The next eruptions occurred in May and in November 2010.

9 Quakes Recorded Around Mount Bulusan in the Philippines

At least nine volcanic quakes were recorded near restive Bulusan Volcano in Bicol in the last 24 hours, national disaster management officials said Tuesday.

The National Disaster Risk Reduction and Management Council (NDRRMC) also reported weak emission of white steam from the volcano's northwest thermal vents.

"For the past 24-hour observation period, Bulusan Volcano's seismic network detected nine volcanic quakes. Measurement of sulfur dioxide emission rate yielded an average value of 36.56 tons per day. Weak emission of white steam was observed from the northwest thermal vents from 8:35 to 10:35 a.m. (Monday)," the NDRRMC said in its 8 a.m. bulletin.

Volcano Forces Airport Shut in Indonesia

Ash eruption from Indonesia's Mount Bromo volcano has forced nearby airports to close, leaving several passengers stranded in the east Java region.

Officials say civilian flights to and from Abdurahman Saleh Airport in East Java Province will remain grounded for at least five days. Tourists were not allowed to visit Mount Bromo on Friday.

Volcanic eruption from this mountain killed two tourists in 2004.

Indonesia is home to about 130 active volcanoes.

This follows the deaths of hundreds of people after Mount Merapi started its volcanic activities in late October.

Eruption Alert: More Indonesian Volcanoes Getting Restless

As if things weren't already bad enough in Indonesia, another volcano may be about to blow.

Indonesia straddles the Pacific Ring of Fire - and lately, this nation of islands has been living up to the region's fiery reputation. A number of so-called minor ash explosions from Mount Bromo on Sunday (Nov. 28) caused a nearby airport to close as scientists upgraded the volcano to its highest alert level, according to the Indian newspaper The Hindu. On the same island, Java, Mount Merapi's recent eruptions killed hundreds and prompted mass evacuations.

The eruption watch also continues in the straight just west of Java where Anak Krakatau has also been increasingly active lately.

Still want to visit Indonesia? Try virtual tourism.

The heightened eruption alerts come just a couple weeks after Mount Merapi's relentless erupting killed more than 300 people.

Mount Merapi's devastation has been estimated at $611 million and pyroclastic flows have destroyed huge swaths of forest (and one unfortunately placed golf course), according to the People's Daily Online.

Philippines: 'Explosion-type' earthquake reported at Bulusan Volcano

Legazpi City -- An "explosion-type" earthquake was recorded by the Philippine Institute of Volcanology and Seismology in in Sorsogon Friday night.

In its latest bulletin, Phivolcs said that the quake occurred at around 7:27 p.m. and lasted for about 11 minutes. Clouds, however, prevented state volcanologists to visually observe it.

The statement did not say what distinguished an "explosion-type" earthquake from any other volcanic tremor.

Sulfur dioxide emission rate was measured at 13 tons per day.

About 11 volcanic quakes were also recorded by the seismic network around the volcano during the past 24-hour observation period.

Phivolcs said Bulusan's status remained at alert level 1 and the public was reminded not to venture into the four-kilometer permanent danger zone as sudden steam and ash explosions may occur.

Indonesia's Mount Bromo Volcano Spews Ash into Sky

Jakarta -- Officials say one of Indonesia's dozens of volcanos has shot ash into the air in a minor eruption that caused no injuries.

Earlier this week the government raised the alert level at Mount Bromo to its highest level, telling villagers and tourists to stay off the rumbling slopes.

Government volcanologist Agus Budiono says the mountain, a popular tourist attraction, spewed ash more than 1,600 feet (500 meters) in the air Friday.

Mount Bromo typically erupts about once a year but unlike nearby Mount Merapi rarely spits debris and hot gas far from its crater. However, two people were killed in a 2004 eruption.
