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 eastward to east-northeastward, except at low altitudes later in the day when they could also drift southeastward.

Recent observations: Rockfalls continue to topple the growing lava dome. A rockfall associated with a minor steam and ash emission and M2.3 earthquake at 12:05pm yesterday lofted a photogenic ash plume above the rim. Crews are out again today continuing to make GPS measurements on the volcano's flanks, repairing communications systems, and retrieving and moving instrument packages in the crater.
