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 northeastward, but owing to shifting winds by this afternoon, such ash clouds would drift predominantly northward.

Recent observations: Clouds limited visual observation of the volcano this morning. Field investigations scheduled for today were cancelled. This morning’s seismicity is quiet, with smaller earthquakes once every several minutes. One earthquake larger than magnitude 2 occurred last night at 11:29 pm PST. Periodic loss of seismic signals at some stations is probably the result of burial by snow.
