New eruption of Mount Etna, Sicily, Italy (08/09/2011)

On the morning of 8 September 2011, the New Southeast Crater of Etna has produced its 13th paroxysmal eruptive episode of the year 2011, generating a tall eruption column that moved south-southeast, and provoking ash and lapilli falls on numerous population centers including Trecastagni, Viagrande, San Giovanni La Punta, and the eastern part of Catania.
During this paroxysm, brief explosive events occurred also from various spots on the northern flank of the New Southeast Crater cone.

Earthquake swarm in Askja volcano and Katla volcano

During the night there was a earthquake swarm in Askja volcano and in Katla volcano. The earthquake swarm in Katla volcano might be ongoing, but it is hard to know that for sure at the moment.

The earthquake swarm in Askja volcano are signs that volcano is preparing for a eruption period. But it seems like that magma has been starting to collecting in Askja volcano last year (in March of 2010). This progress also seems to be moving along faster then I did expect last year. But the earthquake swarm that took place during night was because if a possible dike intrusion from Askja volcano that got into the crust inside Askja volcano fissure swarm. So far the pressure of the magma is not high enough to start a eruption and I am unsure how long this progress needs to continue before Askja volcano is ready for a eruption. The largest earthquake that happened during the night was ML3.4 and on around 1 km depth according to the news on Rúv.


The earthquake area in Askja volcano. It is outside the main Askja volcano, but inside Askja volcano fissure swarm, the star marks the location of the ML3.2 earthquake (automatic size). Copyright of this picture belongs to Iceland Met Office.

Earthquake activity continues in Katla volcano as before. Most of the earthquakes are as before just small ones. Currently the earthquakes do not appear to be from dike intrusion as happened last week (5 October, 2011) with the earthquakes that where up to ML3.9 in size (checked data). After this large earthquake swarm activity dropped considerably. But it has been picking up again slowly during the week. But earthquake observation has been difficult due to frequent storms during the past two weeks that have been passing over Iceland. This storms have had wind up to 30m/s and wind gusts up to 56m/s (recorded).

For the moment it is hard to know what happens next in Katla volcano or in Askja volcano. But it is clear that Askja volcano is preparing for a eruption (along with Kverkfjöll volcano). It is clear that Katla volcano is continuing to prepare for a eruption. But it is impossible to know when and how big that eruption might be. Until a eruption takes place, more dike intrusions with following earthquake swarms should be expected in Katla volcano.

Note: I am going to write more on El Hierro volcano (Canary Islands, Spain) later today. When I know more on what is going on in that volcano. But information gathering takes a little time when it is in a language that I do not properly understand yet.

Piparo mud volcano awakens after 14 years
Published: Sun, 2011-12-04 19:52
Kevon Felmine ... r-14-years

Residents of Piparo are living on the edge as the mud volcano that ravaged the village 14 years ago, has begun to threaten their community again. Residents are subjected to sleepless nights as they are haunted with memories of February 22, 1997, when steaming mud crushed houses and swept away cars, livestock and all else in its path. When the Sunday Guardian visited the site off Old Piparo Road yesterday, two new mounds had surfaced, spewing mud several feet into the air at five minute intervals. At the scene was Shammarine Kissoondath, 56, who lives nearby. He said he came to see what was happening as he had been kept awake by strange sounds issuing from the volcano.

He said: “It sounded like gunshots and this morning when I awoke it was still making noise. This is the same sound it made before it erupted in 1997. It is possible that we can have a repeat and maybe this time it could be worse.” He said it only took ten minutes on that fateful day for the massive amount of mud spewing from the volcano to wreak havoc. Boyie Suratt, who lives about 300 feet from the volcano said he, too, has been sleeping restlessly since Thursday. Suratt’s home is nearest the volcano and he said while he does not believe that it will erupt any time soon, no one can predict when and how severe another eruption might be.

“I was home in my gallery around 3 am on Thursday and I heard this sound like people bursting bamboo. We usually get a little noise now and then, especially when it rains because gas is trying to escape. But now the noise has been coming frequently like it have plenty gas down there.” He explained that the rain softens the mud which causes minor explosions. However, he admits that over the past few days the noise levels had increased significantly occurring at an alarming rate. He, too, recalled the drama that unfolded in 1997, saying that a wave of mud several feet high was crumbling any house in its path. Suratt said his home was saved as another house that crumbled was able to forge a barrier in front of his. He said on February 22, 1997, he awoke to mud spewing some 200 feet into the air.

Indonesia closes airport after volcano erupts: official
5 Nov 2011 ... 9a2033.181

JAKARTA — Indonesia closed a domestic airport in eastern Indonesia on Monday after a volcano spewed ash 2,000 metres into the air, an official said.

Mount Gamalama, which forms the entire island of Ternate in North Maluku province, erupted late Sunday and forced an airport in Ternate town at its foot to close Monday, transport ministry spokesman Bambang Ervan said.

“It’s a safety measure. The volcanic ash may pose a risk to planes. If there is no more eruption, the airport may be opened tomorrow,” he added.

The 1,715-metre (5,630 feet) volcano caused some panic when it erupted, Darno Lamane, a scientist monitoring the peak told AFP.

“It shot ash and dust particles 2,000 metres into the sky. There were no reports of casualties or injuries but people did panic for a while, screaming as they ran out of their homes,” he said.

“The situation has calmed and many residents have gone back home. We will continue to monitor the volcanic activity,” he added.

Lamane said that the volcano last erupted in 2003, when no fatalities were recorded.

Indonesia sits on the Pacific “Ring of Fire” where continental plates collide, causing frequent seismic and volcanic activity. The archipelago nation is home to 129 active volcanoes, including 21 on Java.

Europe's tallest and most active volcano, Etna, erupted for the sixth time in 2012, spewing hot lava and ash on Thursday.

The smoke and flames were clearly visible. The Sicilian volcano has erupted three times in the past month, with regular 12-day pauses.

The main eruption is located at the south-eastern crater, not far from Zafferana Etnea village, but so far Italian authorities have not issued any warning of danger to houses and people.

The southeastern crater, born in 1971, has been the most active in recent years. Etna, which is located above the Sicilian town of Catania, often erupts but rarely causes damage.

'Lord of the Rings' volcano erupts in New Zealand

The dormant volcano erupted Monday night in a New Zealand national park, where many scenes from the 'Lord of the Rings' movies were filmed.

Wellington, New Zealand

A volcano quiet for more than a century erupted in a New Zealand national park, spreading thick ash for several miles and causing some residents to evacuate their homes. Some domestic flights were canceled Tuesday.

Mount Tongariro spewed ash and rocks for about 30 minutes late Monday night after a few weeks of increased seismic activity. It didn't cause any injuries or damage in the sparsely populated central North Island region. Tongariro National Park has three active volcanos, is a popular tourist destination and was the backdrop for many scenes in the "Lord of the Rings" movies.

RELATED World's most active volcanoes

Some residents left their homes as a precaution, and authorities temporarily closed roads. National carrier Air New Zealand canceled or delayed domestic flights to towns near the mountain, though by Tuesday afternoon, it said it was resuming service to locations where the ash cloud had cleared. No international flights were affected.

Police said a witness to the eruption described flashes and explosions followed by a cloud of ash coming from a hole in the north face of the mountain. The Department of Conservation said three hikers were staying in a hut on the opposite slope of Mount Tongariro when it erupted but they walked out of the area safely.

Steve Sherburn, a volcanologist at the government agency GNS Science, said the eruption spread a layer of ash one or two inches thick for several miles. He said he'd heard reports of ash traveling on wind currents to coastal towns 60 miles away. He said the eruption was likely caused by steam pressure building within the mountain.

The nation's civil defense ministry said eruption activity was subsiding though it still urged caution for people who were in the vicinity of the volcano. The park has closed hiking trails and sleeping huts on the mountain for now.

New Zealand is part of the Pacific's "Ring of Fire" and has frequent geothermal and seismic activity.

Sherburn said it was too early to determine whether the latest eruption was the start of a renewed cycle of activity. ... ew-Zealand

Groot cluster vulkanisch gesteente drijft in Stille Oceaan

WELLINGTON - In de Stille Oceaan drijft een groot cluster van vulkanische steen, met de omvang van bijna 26.000 vierkante kilometer.

Het lijkt op een ijsberg en bestaat uit lichtgewicht puimsteen, dat is uitgestoten door een vulkaan onder water, aldus de marine.

.De 'stenen ijsberg' werd donderdag door een vliegtuig van de luchtmacht ontdekt, ongeveer 1000 kilometer uit de kust van Nieuw-Zeeland. De marine werd gewaarschuwd en die stuurde er een schip op af.


''Het was het vreemdste wat ik heb gezien in 18 jaar op zee'', concludeerde luitenant Tim Oscar van het marineschip Canterbury. ''Zo ver als ik kon zien, lag een veld puimsteen dat op en neer bewoog met de deining.''

Wetenschappers die met het marineschip meevoeren, denken dat de puimsteen afkomstig is van de vulkaan onder water Monowai, die onlangs actief was. ... ceaan.html

The pumice "island" floating in the South Pacific, spanning an area bigger than Israel, may be the result of an underwater volcano spewing lava.
CREDIT: YouTube Screenshot, NZ Defense Force

An "island" of floating pumice rocks bigger in area than Israel has been spotted in the South Pacific, New Zealand's Royal Navy said.

Officers on a Royal New Zealand Air Force ship saw the rock raft southwest of Raoul Island yesterday (Aug. 9). It measures an astounding 300 miles (482 kilometers) in length and more than 30 miles (48 km) in width, the Navy said.

Lieutenant Tim Oscar, of the Royal Australian Navy, described the rocks as "the weirdest thing I've seen in 18 years at sea," according to the Australian Associated Press.

"The rock looked to be sitting two feet above the surface of the waves, and lit up a brilliant white color in the spotlight," Oscar told AAP. "It looked exactly like the edge of an ice shelf."

Pumice forms when lava from a volcano cools rapidly. Trapped gas in the hardening lava creates pores in the rocks, which allow them to float. The Navy said scientists believe these chunks off New Zealand's coast were likely spewed to the surface by an underwater volcano, possibly the Monowai seamount, which has been active along the Kermadec arc. Officials said the phenomenon is probably not related to the eruption at New Zealand's Mout Tongariro, which sent ash 20,000 feet (6,100 meters) into the air earlier this week.

A group of researchers from GNS Science, a government-owned firm, were traveling nearby on another military ship. That group changed course to collect samples of the pumice, which will be analyzed to determine where the rocks came from, the Navy wrote on its Facebook page.

Recent studies have suggested that pumice floats played an important role in the evolution of life on Earth since these "islands" can drift over long stretches of ocean, ferrying animals, plants and even colonies of microbes across water barriers. ... cific.html

A new survey suggests that the chamber of molten rock beneath Santorini's volcano expanded 10-20 million cubic metres – up to 15 times the size of London’s Olympic Stadium – between January 2011 and April 2012.

The growth of this 'balloon' of magma has seen the surface of the island rise 8-14 centimetres during this period, a team led by Oxford University scientists has found. The results come from an expedition, funded by the UK's Natural Environment Research Council, which used satellite radar images and Global Positioning System receivers (GPS) that can detect movements of the Earth's surface of just a few millimetres.

The findings are helping scientists to understand more about the inner workings of the volcano which had its last major explosive eruption 3,600 years ago, burying the islands of Santorini under metres of pumice. However, it still does not provide an answer to the biggest question of all: when will the volcano next erupt?

Japan's Mount Sakurajima volcano dramatically erupts live on camera

Described as "a stronger than usual explosion" by volcanic activity specialists, the Sakurajima eruption was captured by four live cameras set up by the Japanese Ministry of Land, Infrastructure and Transport.

The volcano, located in Japan's southern Kagoshima region, erupted at 20:42 local time (11:42GMT) on Tuesday and sent a plume of ash 15,000ft in the air, according to Japanese authorities.
