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: Sunny weather again prevails and the crater is clear this morning. A small rockfall at 0927 PDT generated a small ash cloud that drifted slightly above the crater rim and was captured on the volcanocam. The small “drumbeat” earthquakes are still very small and less frequent than is June, occurring up to 10 minutes apart. However, previous decreases in earthquake magnitude and frequency have not been accompanied by any detectable slowing in extrusion rate. Rockfalls off the new dome and few somewhat larger earthquakes continue to occur several times per day. Clouds of ash and steam will continue to occasionally rise above the crater rim as the result of rockfall activity.
