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 broadly southward to westward early, and shift to broadly southward to eastward trajectories later.

Recent observations: Dry conditions and rockfalls continue at the mountain, and the crater is veiled with a haze of dust and ash. As the central part of the new dome sags and the active part migrates westward, frequent rockfalls expose hot material, which contribute to conspicuous and persistent glow visible at night. Seismicity remains largely unchanged over the past few days and is characterized by a low level of small earthquakes punctuated several times per day by larger earthquakes associated chiefly with ongoing dome collapse.
