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: Stormy weather has moved back into the region and clouds obscure views of the volcano. At 8:20pm local time Saturday evening, a M3.4 occurred at the mountain. This earthquake, the largest to have occurred in over two weeks, may be associated with crumbling of part of the actively growing spine. Such episodic large quakes, which occur amidst the constant background of very small earthquakes, are not unusual for the type of eruptive activity that is ongoing.
