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 above the crater rim today would drift eastward to northeastward.

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. Poor weather conditions this week have prevented any field work. There have been no visual observations of the new dome growth since December 18.
