Sunday observations from the USGS
Recent observations: Clouds and rain obscure the volcano
this morning. Since midnight Saturday, nearly 8 inches of
rain have fallen at the mountain, raising river levels and
increasing flow from the crater. In the past few days, 8
large earthquakes (M2 to 3) have occurred. Similar
swarms of large quakes occurred in November and
December. Those in December were attributed largely
to breaking up of the whaleback. When weather allows,
crews will conduct observation flights and deploy more
equipment to the crater. On a historical note, today
marks the 25th anniversary of the first steam explosion
of Mount St. Helens in 1980, an event that unequivocally
showed its reawakening from a 123-year slumber.
