Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds that rise up to about 15,000 feet above the crater rim (about 23,000 feet above sea level) today would drift to the northwest. Higher-altitude ash clouds would also drift to the northwest early in the day, shifting to the north to northeast later in the day.

Recent observations: Small rock falls continue from the growing lava dome. Larger ones may produce ash plumes that are visible above the crater rim. Patterns of earthquakes and ground deformation remain unchanged from recent trends.
