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 northeastward.

Recent observations: Eruptive conditions remain unchanged as dome growth continues. Seismic signals generated by rockfalls from the crater walls and glacier snouts, as well as from the lava dome, dominate the seismic records.
