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 southeastward.

Recent observations: The mountain remains relatively quiet with clear weather conditions and superb visibility. A few small earthquakes and continued rockfall accompany the extrusion of lava onto the crater floor. Yesterday field crews installed a new broadband seismic station and fixed existing tiltmeter installations.
