Mt. Fitzherbert
USGS Update 2005-Jul-20 08:30
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.
Recent observations: Another notable (M3.3) earthquake occurred last night at 10:20 pm. As has been common with these events, an associated rockfall generated a small ash plume that rose slightly above the rim of the volcano. After the event seismicity returned to the usual level of one small earthquake every 4 to 7 minutes.
