Alaska Shaking and Rattling Like a Popcorn Pan

Posted by feww on February 12, 2010

BAD NEWS for Oil Companies!

Long Waves of  Seismic Activity Striking Alaska

Large swarms of low to medium strength quakes have been striking Alaska since early February.

The current seismicity in the region could translate into enhanced volcanism in the region or very large eruptions from Alaska’s more active volcanoes.

Both the ongoing seismicity and the prospect of enhanced volcanic activity in Alaska bode ill for the oil companies that are operating in the face of the fragile ecosystems in the region.

Week 33 Volcano Watch

Posted by feww on August 21, 2008

13 August-19 August 2008

New Activity/Unrest:

Piton de la Fournaise. The massive Piton de la Fournaise on the island of Réunion is one of the world’s most active volcanoes. It is seen here in 1977 with a fresh black lava flow descending the outer NE flank of the shield volcano to the sea. An unvegetated summit lava shield (upper left) was constructed within an 8-km-wide caldera that is breached to the sea. Its sloping northern rim is marked by the diagonal vegetation line at the left. More than 150 eruptions have occurred since the 17th century, mostly from vents within the caldera. (Caption:Global Volcanism Program ).

Ongoing Activity:

The Weekly Volcanic Activity Report is a cooperative project between the Smithsonian’s Global Volcanism Program and the US Geological Survey’s Volcano Hazards Program. This page is updated on Wednesdays, please see the GVP Home Page for news of the latest significant activity.
