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 south-southwest early, with a shift to the southeast later in the day.

Recent observations: A higher cloud ceiling affords the opportunity for fieldwork at the mountain today. Crews will be mapping, deploying and maintaining seismic instrumentation, and collecting samples over the next two days, weather permitting. Monitoring instruments continue to record small earthquakes, rock falls and steady ground deformation consistent with on-going extrusion of the lava dome. There have been no significant changes in conditions over the last 24 hours.
