Hi all, I'm new to this forum, but not new to volcano-watching.
dgavin - I believe you'll find that much of the water stored in this area is embedded in alluvial till - deep sand and gravel deposits from receding glaciers. Hope that helps a little.
I have a question that someone here might be able to answer: The geologists mentioned "repeating earthquakes" that showed up at 23:52 3/28. I cannot find a reference as to what they mean, that is IF the scientists know. Does anyone here know what they are and what they signify?
BTW - the 1966 eruption lasted for 2 1/2 years and low frequency sound waves were picked up at seismographs outside Fairbanks.:surprised
