Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds that rise above the crater rim today would drift southeastward, although low altitude winds would carry some ash westward.

Recent observations: The volcano is clear this morning, and crews are in the field. If wind conditions permit, we will install two instrument packages on and near the new lava dome. A GPS and seismometer on the new lava dome and a video camera and gas sensor between the new and old lava domes. We will also make visual and thermal-sensing observations and service a seismic station. The existing GPS “spyder” on the southeast part of the new lava dome continues to move southeastward about 2 meters per day.
