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 early today would drift south-southeastward.

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. The volume of the dome measured on October 24, 2005, was 70 million cubic meters—about 90% of the volume of the 1980-to-1986 dome.
