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 north-northeast in the morning. In the afternoon the trajectory would be predominantly due east.

Recent observations: Unsettled weather including possible electrical storms will make visual observation of the mountain difficult today. Seismic, hydrologic and geodetic instrument streams show no significant change in patterns of earthquake activity or strain. Seismicity continues as periodic small earthquakes, recurring every few minutes. There are occasional larger events, typically < M3, e.g., an event at 7:12 am PST this morning. 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.
