Nov. 18 – Active Alaska volcano calms down – for now

ANCHORAGE, Alaska (AP) — One of Alaska’s most active volcanos has calmed down since spewing ash up to 35,000 feet into the air over the weekend, but scientists said Monday the volcano has a pattern of prolonged eruptions of varying intensity. They’re not ready to consider this explosion over.
It is on an ORANGE ALERT from the USGS

Sunday – 4.5 quake at Soldotna, Alaska < MAP … it is 55 miles from the active Redoubt volcano

Alaskan Earthquakes affect Yellowstone

A brief excursion to Alaska illustrates the interactivity of tectonic plates, in this case the North American plate. According to reports in 2002 a major earthquake in Alaska set off a chain of smaller earthquakes in the Yellowstone National Park more than 2,000 miles away. Within hours geysers in the park changed their eruption patterns, according to the journal “Geology”. Researchers believe that earthquakes keep geysers alive by periodically shaking loose clogged channels. The Alaskan earthquake was one of the strongest in North America in the past 150 years.

Thousand smaller quakes
Robert Smith of the University of Utah says that this study shows that large earthquakes at large distances can have profound effects on the Yellowstone geysers and that they did not expect to see these prolonged changes in the hydrothermal system. The geysers showed changes just a few hours after the shock waves from the 3 November Alaskan earthquake passed through triggering more than a thousand minor local earthquakes with the shock waves, many of them near hot springs and geysers, altering water and steam pressure in the geysers, opening new channels and unclogging others.

“… his audio file was done on Friday, on the Byte Show. The guest is Aaron Kaplan. The first seven minutes got cut off by mistake. About three minutes into the audio, Aaron starts talking about Yellowstone, then the New Madrid and the Gulf. “

It is very shallow … Shakemap report

It has a link to an “uncertainty map” with 2 large blobs on it.  No USGS (zoomable) map out yet … it will go here when available.
