Mt. Fitzherbert
USGS Update 2005-Jul-27 08:15
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 generally southward to eastward, except at low altitudes where they could also drift westward.
Recent observations: Rockfalls continue to topple the steep spine on the growing lava dome, and its height has been now been greatly diminished. Crews had a busy and productive field day yesterday, and are out again today to make more GPS measurements on the volcano's flanks, to continue geologic mapping of the mountain, and to measure volcanic gases.
