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.
