Etna erupts again.

Posted in Italy with tags , , , on April 12, 2011 by italyicelandvolcanoes

It seems as though the regions of Iceland and Italy are having a fairly quiet season in terms of volcanoes. Mount Etna, however, erupted on April 10. This is the third eruptive episode of its type to occur in 2011 on the Southeast crater. The type of eruption is strombolian: there was a lava flow, the expulsion of tephra, a gas column and lava fountaining. There were also small pyroclastic flows due to the presence of snow. Though the eruption seemed to have more or less subsided after two days, little is known as to whether more activity will ensue.

This image can be found here. It is an image of a small pyroclastic flow, created as lava passed over snow.

Volcanic Activity for Russia March 30 to April 8

A Map of Kamchtka

KARYMSKY: Increased seismic activity between March 25 through April 1, with thermal anomaly being detected along with ash plumes reaching heights of 5km and drifting 55km in many directions.

KIZIMEN: Volcanic earthquakes continue at a high rate, with a possible eruption on April 1 producing an ash plume that rose to 4.3km and drifted East. Another possible eruption occurred on April 6.

KLIUCHEVSKOI: Possible eruption on the 30th of March, producing an ash plume rising to 5.2km and moving Eastward.

SHIVELUCH:Increased seismic activity with a multitude of ash plumes reported.


Guatemala Update

Posted in Uncategorized on April 7, 2011 by zaradaula

According to the Global Volcanism Program, Fuego in Guatemala has been erupting the last two days. It produced ash plumes that rose up to 700 m above the crater and lava flows that traveled nearly 200 m down the South West side of the volcano and created block avalanches.

Also in Guatemala, Santa Maria erupted on March 28, producing ash plumes that rose 800 m above the lava dome. This plume traveled North East and deposited ash on the town of Quetzaltenango, which is 10 km away. Then in the last couple of days, explosions created ash plumes slightly smaller (only 400-700 m) and drifted South. Avalanches were produced and traveled down the South West and Eastern flanks of the volcano.

I couldn’t find any current footage of either volcano, so I found photos instead.

In early March the Indonesian volcano Karangetang began to show signs of being active and potentially dangerous. By mid March the country’s National Disaster Management Agency had evacuated up to 1,200 people from the two villages built on the slopes of the volcano.

The 7,500 feet high volcano, Karangetang, being one of the country’s most active volcanoes had already erupted in August, killing four people. By March 21st lava flows had started to run down the flanks of the mountain.

Seismicity had decreased by March 24th, and the warning level was lowered to a 3.


Another volcano to have erupted on the same weekend as Karangetang was Mount Merapi. By that Saturday ( March 19th) it had already buried 21 houses. The eruption has claimed no lives, and few injuries.

Activity Spotted at Rabaul

Posted in Papau New Guinea on April 5, 2011 by the inevitable change

If readers recall, the first blog that I posted about Papua New Guinea highlighted two of the region’s infamous volcanoes. One of those volcanoes, Rabaul has recently been observed by the Darwin VAAC. On March 29, 2011 an ash plume was spotted coming from the caldera Tavurvur. The plume ascended to approximately 10,000 feet.


Ecuadorian/ Colombian Update!!

My favorite volcano in the world

Unfortunately there isn’t any new activity going on in my region. I thought maybe I might say some words about Ecuadorian Volcanism. Perhaps My favorite volcano in the world is Cotopaxi. I went there in 2008, and was amazed by its size and shape. It has erupted as recently as 1877. It was thought to be the tallest volcano in the world before the discovery of Mt. Everest.

One Year Later, Eyjafjallajökull

Posted in Iceland, Uncategorized with tags , , , , on March 30, 2011 by italyicelandvolcanoes

With April fast-approaching, we are now reaching the one year anniversary of the 2010 Eyjafjallajökull eruption. Eyjafjallajökull is a volcano located in Southern Iceland which took the global spotlight when its ash plumes shut down air travel across Europe. Many were surprised when the volcano erupted, because it has been historically less active in comparison to Iceland’s numerous other volcanoes. The last eruption took place over the course of 14 months from 1821-1823. Yet, regardless of what was or was not expected, Eyjafjallajökull certainly erupted, and the media and various governments responded in a multitude of ways. With many sources having covered the eruption in detail, I saw it fit to take a look at the reaction to the eruption, and plume that surpassed 8 km on numerous occasions throughout April and May across Europe.

One of the many ways that the media responded was through political cartoons.

The worry proposed in this cartoon is that the ash plume would do serious damage to the environment. Though this provides an interesting topic for a cartoon, in the end, climatologists determined that the atmospheric effects would be short lived. This is not to say that the immediate effects were not devastating. Some stunning photographs of the eruption can be found here.

The reality painted in this cartoon, however, was far more real. Over three-quarters of European airspace was closed for a week. Thousands of flights and millions of airline passengers were affected. The financial loss for airline companies was approximately $2.8 billion. This does not even include the drop in tourism and other economic issues. Like the cartoon says, Eyjafjallajökull happens, and we can only hope that it doesn’t in the future, though that hope is likely fruitless.

Recent Volcanic Activity in Hawaii, March 9th-24th

Posted in US/Mexico on March 29, 2011 by sarahnye1

As of March 10th, the East Rift Zone eruption  had a lack of activity.

The video link above is from March 5th, but it is a very interesting look at the Kilauea crater collapsing.

The Kamoamoa fissure eruption was probably the most exciting thing Hawaii has seen recently. These pictures show the thickness of the flow produced by the eruption.

Since March 9th, the end of the Kamoamoa fissure eruption, no lava has been erupted on the east rift zone. The floor of Pu`u `O`o is still filled with rubble, and there is no active lava in the area. The summit of the mountain has been active this week, as the inflation and deflation of the lava lake in the Halema`uma`u Overlook vent has caused it tto disappear.

This week, some small rock falls have also been observed. The volcanic gas emissions have decreased over this past week but still remain high, resulting in high concentrations of sulfur dioxide downwind, from March 16th to 18th.

Two earthquakes were also felt beneath the Hawaii island this week, one on the 18th and the other on the 20th.

Earthquake in Japan!

Posted in Japan/Philippines on March 29, 2011 by nallurihp

As we all know, there’s been a great deal of activity in Japan. Many of us have been following the news, and unless you’ve been living under a rock, you know that there’s been a massive earthquake in Japan. The earthquake warranted a 9.0 on the Richter scale, the second biggest earthquake recorded. This earthquake had some devastating consequences for the people of Japan. The estimated damages alone could cost up to 309 billion US dollars. The earthquake was so strong that it moved Japan nearly 8 feet closer to the States, and it caused a tsunami that caused even more damage. As of now there are 11,004 deaths, 2,778 injured, and 17,339 missing. To add insult to injury the earthquake caused explosions at multiple nuclear power plants, and the radiation contaminated much of their food supply.

However the people of Japan can’t relax just yet, the worst is not yet over. It is possible that the earthquake could trigger some of the many active volcanoes that are in Japan. Kirishima has already had a small eruption.

Here are some images of destruction the earthquake has caused:

And above ^ you can watch as the tsunami comes in.

An image of Shiveluch from the 25th of February, 2011

KARYMSKY: Moderate amounts of seismic activity were detected between the 10th and 18th of March according to KVERT, with ash plumes rising to heights of 5.8km.

KIZIMEN: KVERT also reported of seismic activity increased between March 11th through the 18th, with many earthquakes and seismic activity being detected today. ash plumes traveled  about 219km SE and W, and the march 20-22 eruptions reaching heights of around 6 to 7km.

SHIVELUCH: Seismic activity occurred between the 11th and 18th of March with ash plumes reaching heights ranging between 3 to 8 km. Ash Plumes drifted approximately 312 km W and NW.
