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 would drift north-northeastward early in the day, and shift to more southward to eastward trajectories later.

Recent observations: Dry conditions and rockfalls continue to stir ash within the crater, and a persistent, but lazy, gas and vapor plume rises from the dome. As has happened in the past, large rockfalls from the dome generate conspicuous ash plumes that can rise above the crater rim and drift downwind. Camera images show continued slumping of the central part of the dome and westward motion of the presently active area.
