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 northeast.

Recent observations: Partly cloudy conditions prevail this morning, but the mountain is visible from the Johnston Ridge Observatory. Similar conditions are expected for the remainder of the day. Seismicity continues as very small periodic earthquakes, recurring every few minutes, punctuated by occasional larger but still small events. The large earthquakes are typically less than M3 and occur at an average rate of less than 1 per day. 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.
