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 northeastward.

Recent observations: The weather is improving and field crews are hoping to visit the crater today for the first time since May 30 to make repairs and observations. Seismicity and photos from the Brutus camera on the northeast crater rim indicate that lava extrusion and rockfalls from the growing spine are continuing. Some of the larger rockfalls can be expected to cause dust plumes that could rise above the crater rim and be visible from Johnston Ridge Observatory and elsewhere in the vicinity.
