Mt. Fitzherbert
USGS Update 2006-Jul-17 11:00
Potenial Ash Hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds rising above the crater this morning would drift ENE throughout the day.
Recent observations: Another sunny day today, allowing good views of the crater. Late yesterday afternoon, a steam plume (accompanying a rockfall) rose about 1000 feet above the crater rim and dissipated within minutes. Multiple small rockfalls per day are the norm at present, and this pattern is likely continue, together with very low background seismicity. More rockfalls may produce a plume or cloud of ash that could rise a few thousand feet above the crater rim.
