Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that any ash clouds rising above the crater rim today would drift northward in the morning and eastward in the afternoon.

Recent observations: Monitoring instruments on Mount St. Helens have remained operational throughout the recent heavy snow fall. A shallow magnitude 1.9 earthquake occurred in the crater at 05:51 AM this morning. Slow ground deformation, measured with tiltmeters and GPS, indicates that ongoing extrusion of the lava dome continues.
