USGS Update 2007-Sep-21 10:31

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that any ash clouds rising above the crater rim today would drift to the east-southeast.

Recent observations: Clear weather this morning affords a spectacular view of the volcano, from which a small gas plume can be seen near the top of the new lava dome. Seismicity levels remain low and consistent with continued slow extrusion of new lava. Field crews yesterday had their work day cut short by inclement weather. Today crews are hoping to continue geologic mapping efforts, repair/move several pieces of monitoring equipment, retrieve rock samples from the new lava dome, and measure gas compositions in the plume.
