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. Later in the day ash clouds at low altitude would also drift northward.

Recent observations: Yesterday, scientists were able to gage the flow rate of a crater stream, collect water samples, and download data from sensors placed in several springs. Clouds stymied other planned work. Strong winds late in the day and evening made lots of noise on flank seismometers such as Studebaker, June Lake, and Cedar Flats, but a magnitude 2+ earthquake is embedded in the storm noise shortly after 8 pm PDT. The level of eruptive activity remains unchanged from recent trends.
