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 westward at low altitudes and west-southwestward to southwestward at higher altitudes.

Recent observations: Field crews are taking advantage of today's clear weather to work on telemetry linkages and to make visual observations. The active part of the lava dome has become visually bigger, but as yet we cannot quantify the change. At 10:40pm Wednesday a relatively large earthquake punctuated the on-going procession of small “drumbeat” earthquakes. Otherwise, patterns of seismicity and deformation remain unchanged.
