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 follow variable trajectories with altitude and time. Early in the day, clouds would drift south-southeastward. As the afternoon progresses, winds will shift and clouds would drift weakly northward at low altitudes, but strongly eastward at higher altitudes.

Recent observations: Despite clear skies to the south, the volcano remains mostly obscured by clouds again this morning. It appears that recent snowfall has covered the crater. Seismicity continues at roughly the same rate as that of mid-December. Small earthquakes (M<1.5) occur 2-3 times per minute beneath the new dome. The GPS receiver located on new dome rock continues its remarkably steady east-southeastward progression. GPS receivers on the 1980-86 dome, which lies to the north, continue their trifling northward travel.
