Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds rising above the crater today would be transported toward the east or northeast.

Recent observations: Over the past day, a few small rockfall events followed the large event on June 13, 2006, as indicated by small signals on crater seismic stations. Thus the processes breaking apart the spine that grew between March and May of this year continues. The lobe on which the decrepitating spine stands continues to rise, accompanied by small “drumbeat” earthquakes that recur at the rate of one every few minutes.
