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 westward to west-northwestward.

Recent observations: The volcano is hidden by clouds this morning, but data from field instruments indicate no significant changes in seismicity or ground deformation overnight. Qualitative analysis of recent photographs suggests that the rate of extrusion at the north end of the new lava dome continues at about 2 to 3 meters (6 to 10 feet) per day. More precise measurements await installation of additional surveying targets on the dome. Good weather is forecast throughout the week, so field crews should be out on several days.
