USGS Update 2006-Apr-04 10:30

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 to the north.

Recent observations: Mostly clear skies allow views of the snow- covered volcano this morning. Crews are in the field taking advantage of this break in the weather to repair monitoring instruments, measure emissions of volcanic gasses, conduct infrared imaging of the growing lava dome, and hopefully to restore some of the remote cameras. Seismicity is quiet, with smaller earthquakes once every several minutes, and GPS receivers show that solidified dacite lava continues to extrude slowly.
