Mt. Fitzherbert

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

Recent observations: Weather at the volcano is clear this morning as a nearly full moon brushes the western horizon. Seismicity remains in the pattern of the past week, with a ~M-1 earthquake occurring every other minute or so. The three GPS receivers in the crater continue their slow rates of displacement, which suggests that the dome continues to be extruded, albeit slowly. Crews yesterday repaired the voice-communication system that enables our radios when working around the volcano.
