Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that any ash clouds rising above the crater rim today would drift to the south-southeast or southeast.

Recent observations: The volcano is visible from Johnston Ridge this morning and a plume of condensed water vapor can be seen rising from the active lava dome and drifting to the southeast over the crater rim. Plumes such as this one form when water vapor, a gas that cannot be seen, rises above the hot dome, cools in the atmosphere, and condenses to form visible water droplets. They are more indicative of weather conditions than any change in the ongoing eruption. Seismicity remains at a low background level and a GPS instrument on the active dome continues to move away from the vent at a constant rate. If weather permits, field crews will make observations and service monitoring instruments at the volcano later this week.
