Dear Friends:
It was forty years ago this week that I was visiting my sister out in Victoria B.C. when we heard a deep, remote, extensive boom that sounded a bit like distant thunder....... only different somehow!
When we heard about it on the TV everyone went out to look and ...... sure enough....... there it was!
Scientists knew that something wicked had been brewing beneath this stratovolcano in Washington State that lies between Seattle and Portland.
During a period of less than two months, a bulge the size of a town had appeared on its north flank, a vast pimple of unusually positioned magma. But the singular ferocity and unusual dimensions of the eruption took almost everyone by surprise, serving as a reminder of how much the science of volcanology had yet to learn.
“The 1980 event was really a landmark for volcanology writ large,” said Seth Moran, the scientist-in-charge at the U.S. Geological Survey’s Cascades Volcano Observatory.
