Mt. Fitzherbert

Aerial views taken on 2005-Aug-10

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 southward to south-southwestward.

Recent observations: Despite a large (M3) earthquake and an associated rockfall at 5:11pm yesterday, seismicity and deformation within the crater remain largely unchanged over the past several days. Images from a camera at the mouth of the crater show the new lava spine continuing to emerge from the ground at a rate of several meters per day. Results from yesterday's field work show that temperatures of the new dome remain as hot as 660 degrees C (1220 degrees F) in cracks and on faces newly exposed by rockfalls, and that the amounts of volcanic gases being emitted appear to have declined about 2 fold since they were last measured at the end of July.
