Icelandic volcano warming up for eruption: Small glacier flood continues at Katla

This is going to be a short blog post. As I am going to be short of table and a cheer for few more days.

It seems that Katla volcano is warming up for a eruption. As I did mention in last blog post. But there is more to this. As the glacier flood that started on the 28. April 2012 continues according to a email that I got from an geologist working at Iceland Meteorological Office. But that suggests two things. That there is currently an ongoing melting of glacier taking place in Katla volcano, or there is a slow drainage taking place from some area in Mýrdalsjökull glacier. But given increased conductivity following this it is clear that this water has been in contact with magma. But that can be seen with the increased conductivity in the water.

There have not been many earthquakes following this events. But from the earthquakes that have happened. It seems that most likely source for current events is close to or the same area that erupted in July 2011. But at the moment this is just speculation based on limited data. It has not been confirmed so far.

Japan's Mt. Fuji a Ticking Time-bomb? Scientists Find 30 km Long Active Fault

Image
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.

Pagan Island Volcano Erupts in Mariana Islands

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.

Increased Volcanic Activity at Mt. Baekdu

© Korea Times fileCiting the rise of the surface temperature of Mt. Baekdu, geologists predict its eruption in a couple of years.
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.

Popocatepetl Volcano Threatens Millions with Gas and Ash, Mexico on High Alert

Mexico City just 40 miles away from volcano throwing poison gases a mile up into the air over Puebla state

Mexico remains on high alert as the Popocatepetl volcano continuous to spew gas and volcanic ash into the air.

Mexico's National Centre for Disaster Prevention raised the threat level in April to its third highest warning in a seven-step scale. This indicates the possibility of magma expulsion and eruptions of increasing intensity.

Mount Asphyxia Volcano Erupts - South Sandwich Islands

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.

Nicaragua Monitors Microseismic Activity Increase in Volcano

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 Masaya's 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.

Underwater Volcanism - Antarctic ice melting from below

"Underwater volcanism is also sublimating portions of the Antarctica ice mass from underneath. In 2004, a research team led by Eugene Domack, aboard the research vessel Lawrence M. Gould, made a remarkable discovery of a massive underwater volcano off the coast of Antarctica using a deep water submersible vehicle equipped with a cadre of sensors and video cameras. The volcano was 2300 feet (700 meters) tall. The British team findings confirmed the volcano was still active and was contributing to the melting of the ice sheet from beneath the Antarctica land mass." - The Extinction Protocol, page 160 - 2010

Long Valley super-volcano caldera rattled by earthquake swarm

Mammoth Lakes, California - A series of 6 tremors have erupted at the Long Valley super-volcano caldera over the last 24 hours- two yesterday, and four tremors today. The tremors today were a 1.1 mag (3.2 km), a 2.5 mag (4.5 km), a 1.6 mag (4.5 km) and a 1.2 mag (2.8 km). This could be the beginning of a swarm so we'll keep monitoring events and look for updates.

Strong activity continues at Indonesia's Mount Lokon volcano

Head of Data Center for Information and Public Relations of the National Disaster Management Agency (BNPB), Sutopo Purwo Nugrogo said Lokon was shaken by another volcanic tremor in Tomohon, North Sulawesi. In addition, the volcano is stirred by 1 to 3 shallow tremors every 5 minutes. If activity continues to increase at the volcano, officials fear an eruption could be imminent. The volcano remains at alert status 3 for now. The public is admonished to monitor the news for the latest updates about the volcano and a 2.5 kilometer exclusion zone remains in effect around the volcano's parameter.
