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 eastward to southeastward.

Recent observations: Weather permitting today several crews will head to the field to deploy GPS spiders on and near the new lava dome, repair a seismic station, conduct a gas-sensing flight, dredge rock samples from the dome, and take aerial photographs. Seismic and GPS data show no significant changes.
