I was just at the Mount St Helens National Park this summer were a Ranger said that Harry went to talk to some school kids who begged him to leave so he agreed to. Then the media pressured him to return so they could have a story.
Camped on the shore of Spirit Lake as a Boy Scout. There's still a lake, but it's not where I left it.Just in case you think that I'm fixated on the Glacial Floods of the Last Ice Age - the subject of my dissertation for my Masters, I'm just as kooked by Fort Rock and the sandals found there, UNDER a layer of ash dumped by the former Mount Mazama - now known as Crater Lake. Just how spooky is that? Those people must have looked up from the fishing - and yes, Fort Rock was at the end of an extensive LAKE - that thought 'WT.........................................?' before the ash and pimice storm hit them. I'm betting that some day we'll find some human remains in the vicinity - those of early Americans who couldn't run fast enough to get under cover in the caves nearby.
As a Geology student, we used to talk about microseismicity in subduction and fault zones. We were talking 2.0 and smaller. Given the Richter scale is logarithmic, with each full number being one order of magnitude stronger, a quake of 6 or more is a great release of energy.I was wrong when I said that small earthquakes relieve the tension (I was right when I said I wasn't an expert); read an article where they said a bunch of small earthquakes could be a precursor - it depends on the type of earthquake.
Prior to the eruption of St. Helens, my GF was attending UW, and as she was talking on the phone with me, a 4+ earthquake happened. I could hear stuff rattle there in her dorm room (old copper phone lines were *way* better than cellular).
