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 southward in the morning and southeast in the later part of the day.

Recent observations: Visibility into the crater is good this morning, and scientists will attempt some fieldwork despite the strong winds today. The volcano continues slow extrusion of a lava spine, and seismometers are registering very small earthquakes periodically. At 3:45 PM yesterday, a magnitude 3.4 earthquake punctuated the regular pattern of magnitude 1-3 earthquakes. A resulting small plume of ash rose above the crater rim and quickly dissipated.
