SEATTLE (AP) — Small earthquakes at the rate of one or two a minute on Monday had seismologists keeping a close watch on Mount St. Helens.
Scientists were not sure what was going on beneath the southwest Washington volcano and planned a full day of investigations.
Seth Moran, a seismologist with the U.S. Geological Survey at the Volcano Observatory in Vancouver, said that while a major blast was unlikely, there was potential for explosions within the crater that could throw rocks as far as the rim.
The earthquake swarms began Thursday and on Sunday the Geological Survey issued a notice of volcanic unrest, saying there was “an increased likelihood of a hazardous event.”
Glad we don't live any closer than 3 1/2 hours away!
