USGS Update 2008-Jan-12 08:57

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 eastward early in the day, shifting to a more southeastward trajectory later in the day.

Recent observations: Poor weather precludes views of the mountain this morning. At abut 0711 and 0723 local time a pair of moderate sized, but raggedy, earthquakes occurred. Emergent, rather than sharp, onsets suggest that they could involve rockfalls, but the exact nature of these events is under review. Such events indicate that the dome is still active and growing and that the volcano remains in a state of eruption, but do indicate any significant change in eruptive activity.
