Mt. Fitzherbert

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

Recent observations: The crater is obscured by clouds this morning. The small "drumbeat" earthquakes accompanying steady lava extrusion have gotten smaller and less frequent over the past week, but previous decreases in magnitude and frequency have not been accompanied by any detectable slowing in extrusion rate. Rockfalls off the new dome continue to occur several times per day. Clouds of ash and steam may rise above the crater rim as the result of rockfall activity.
