Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds that rise above the crater rim would drift to the southeast in the morning, shifting to a more easterly drift in the afternoon and evening.

Recent observations: The dome-building eruption continues today at a slow and steady pace. Small earthquakes, occurring on average every one to three minutes, reflect the slow lava extrusion, although there was a slightly larger earthquake at 7:09 am. Progress of the eruption currently can only be tracked by instruments (seismometers, GPS receivers, and tiltmeters) because of the low clouds and stormy conditions.
