US Air Force to Move Aircraft as Alaskan Volcano Escalates /Yellowstone EArthquake Swarm/Mega Earthquake Risk for West Coast, US & Canada

Alaska's Mount Redoubt continues to show signs of a full eruption. As a precaution, Elmendorf Air Force Base near Anchorage - 100 miles northeast of Redoubt - was moving some of its aircraft to McChord Air Force Base in Washington. Officials said the base was starting with five C-17 cargo planes and could relocate other aircraft if deemed necessary. "We're just trying to be proactive and protect our assets," said 1st Lt. Erin Slaughter. "Our aircraft support other missions, such as delivering supplies to Iraq and Afghanistan, and this relocation will allow them to still do all those missions even if the volcano does erupt."

The laboratory said the swarm began Dec. 26 and continued into January but that it subsided rather quickly on Jan. 5. The swarm under the north end of Yellowstone Lake consisted of almost 1000 earthquakes with magnitudes ranging up to 3.9. The sequence contained 19 earthquakes of 3.0 or higher. A number of the quakes were felt in the park itself and in surrounding areas, said the observatory. For the entire month of January, 315 earthquakes were located, with 205 associated with the Yellowstone Lake swarm.

The slip events coincide with regular occurrences of what scientists call nonvolcanic tremor, which showed up clearly on seismometers but for which the origins were uncertain. "We are now more confident that the tremor and the slip are both products of the same slip process," said Kenneth Creager, a UW professor of Earth and space sciences and a co-author of a paper describing the research being published Jan. 30 in Science. The findings could have major implications for megathrust earthquakes in the Cascadia subduction zone, an area along the West Coast from northern California to southern British Columbia. Megathrust events are huge earthquakes, often in the range of magnitude 9, that occur in areas where one tectonic plate is forced beneath another.
