Mt. Fitzherbert
USGS Update 2007-Jan-23 08:35
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 mostly eastward.
Recent observations: Skies that are mostly clear this morning afford good views of Mount St. Helens from Johnston Ridge Observatory. A significant rockfall occurred around 9 PM last night, producing a strong seismic signal and leaving a visible trail of dust in the crater. Otherwise, earthquake activity remains very low. Field crews plan to take advantage of today's good weather to perform equipment maintenance, obtain thermal imagery, and make visual observations.
