Ancient supervolcanic flow was actually rather slow, scientists say

An article in The Christian Science Monitor reports on research by Greg Valentine, professor of geology, that tried to quantify the speed at which hot volcanic debris and ash traveled following the explosion of a supervolcano, based on the massive volcanic deposit that erupted from the Silver Creek Caldera in Arizona 18.8 million years ago, and found that pyroclastic flows moved at speeds of about 11 to 44 miles per hour. “The character and speed of the flows will affect how much time you might have to get out of the way,” he said, but “the only truly safe thing to do is to evacuate before a flow starts.” Articles appeared in news outlets that include Huffington Post, Tech Times, KBET-AM in Las Vegas and Space Daily.
