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 predominantly to the west.

Recent observations: Partly sunny conditions are expected again today at the mountain allowing visual observations from the ground and air. 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 is building with motion to the west at about 1 meter per day, consistent with the trend established over the last few weeks. Monitoring data are within the range of typical recent values.
