Eyjafjallajökull Eruption – 2nd Update Apr 15

Posted by feww on April 15, 2010

Eyjafjallajökull eruption intensifies

Eyjafjallajökull eruption 10 times more powerful than Fimmvörduháls Eruption in March: Iceland volcanologist

The eruption which occurred 200 meter beneath the Eyjafjallajokull glacier has intensified after ejecting a 6.7-km plume of ash and smoke into the air and causing extensive flooding south of Iceland,  volcanologist Armannn Hoskuldsson at University of Iceland  said. He noted that the eruption was 10 times more powerful than the March 20 Fimmvörduháls eruption.

“It’s becoming more intense, but there will be no lava—this is purely an explosive eruption,” Reuters quoted him as saying.

Airport operator BAA said on Thursday it expected all flights in and out of London’s Heathrow and Stansted airports to be suspended from 12:00 p.m. due to a cloud of volcanic ash from an eruption in Iceland.

Non-Stop Eruption

Eyjafjallajökull has been erupting for more than 24 hours,  disrupting air traffic throughout northern Europe. Britain’s National Air Traffic Service (NATS) declared Britain’s airs pace a no-fly zone. Only emergency flights are allowed in British air space.

The situation is pretty much the same across the region. Airlines have canceled or diverted thousands of flights from Norway, Switzerland, France, Belgium, Holland, Denmark, Finland and Sweden.

Markarfljót river located to the west of Eyjafjallajökull glacier flooded for the second time last night, a local report said, describing the second flood as “completely unlike the first one.”  The earlier floodwater measured about 4 degrees Celsius and was ice free. The second flood, however, was said to have a high ice content with large quantities of ice chunks measuring up to 15 cm thick The latter flood water was also colder than the first measuring degrees Celsius C. The floodwaters have caused extensive damage to roads and bridges.

The ash fall from the eruption has covered thousands of hectares of land to the east of the glacier Iceland’s fifth largest, in a thick blanket of ash.

Up to 800 people have fled their homes or been evacuated by the authorities.

Earthquakes in Alaska

Posted by feww on July 15, 2008

Earthquake History of Alaska

The earth’s most active seismic feature, the circum-Pacific seismic belt, brushes Alaska and the Aleutian Islands, where more earthquakes occur than in the other 49 States combined. More than 80 percent of the planet’s tremors occur in the circum-Pacific belt, and about six percent of the large, shallow earthquakes are in the Alaska area, where as many as 4,000 earthquake at various depths are detected in a year. Excerpt from USGS.
