USGS Update 2004-Dec-24 09:45

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 drift southeastward early in the day and northeastward later.

Recent observations: The VolcanoCam is again providing clear views of the volcano this morning. A moderate steam plume is rising from the new lava dome and drifting over the south rim of the crater. Yesterday field crews serviced several seismic stations and completed repairs to a key radio transmitter. They were successful in retrieving one of the Spiders (a portable seismic and GPS station slung into place by helicopter) from the old lava dome and replacing it with a newer version. The new lava dome was too steamy to permit placement of a new Spider there or to obtain clear photographs.
