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: Clear weather and only minor dust haze afford good views of the volcano today. Yesterday, two moderate magnitude earthquakes (the largest M3.6) generated rockfalls that produced dust plumes that rose well above the rim and were visible from the metropolitan area. These types of events are to be expected during the current eruptive activity, and will likely happen again. Overall, seismicity at the mountain is relatively low, and there have been no significant changes in seismicity or ground deformation in the past 24 hours.
