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 today would drift south-southwestward early and south-southeastward later.

Recent observations: Ash and dust stirred by winds, a weak vapor plume rising from the growing lava dome, and minor ash plumes caused by rockfalls are drifting over the crater rim. Seismic and deformation data show no significant changes from trends of recent days.
