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 westnorthwest in the morning and northeast in the evening.

Recent observations: A magnitude 3.5 earthquake at 3:13 Saturday afternoon shook loose the top of the highest of the new lava spines, spine 7. The small collapse and avalanche of dome rock generated a short-lived ash plume that rose approximately 2000 feet over the west crater rim and rapidly dissipated. Lava continues to slowly extrude into the southern crater area and is accompanied by small earthquakes and occasional small rockfalls and avalanches. Viewing conditions today are clear.
