Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that any ash clouds rising above the crater rim today would drift mostly southeastward.

Recent observations: The view of the crater and lava dome from Johnston Ridge Observatory is clear this morning. A few small earthquakes occurred in the last 24 hours, all less than magnitude 3. Occasional rockfalls are seen in the seismograms from crater stations. Continued growth of the lava dome is accompanied by very small “drumbeat” earthquakes.
