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 early in the day would drift to the northeast. Later in the day ash would drift to the south and east.

Recent observations: Cloudy conditions with showers prevail this morning and rain is expected to continue into the afternoon. 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, e.g., a M2.7 at 12:28 PDT yesterday afternoon. The active dome continues to build with motion to the west. Monitoring instruments show no significant change in patterns of earthquake activity or deformation from those established over the past few months.
