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 to the southeast.

Recent observations: More clouds and precipitation are expected today at the mountain. Monitoring instruments show no significant change in patterns of earthquake activity or deformation. Seismicity continues as very small periodic earthquakes, recurring every few minutes, punctuated by occasional larger but still small events. The larger earthquakes are typically less than M3. The active dome continues to build with motion to the west at about 1 meter per day. Monitoring data are within the range of typical recent values.
