Mt. Fitzherbert
USGS Update 2004-Dec-20 08:45
Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds that rise above the crater rim today would drift southeastward early in the day, and more south-southeastward later in the day.
Recent observations: Morning clouds again obscure the mountain, but our field sensors indicate no significant change of activity. The recent swarm of large earthquakes (about magnitude 3) has diminished. A few large quakes (up to about M2.3) occurred overnight amidst the ongoing pattern of frequent smaller earthquakes, but the size and frequency of those larger quakes has declined. Data from the gas-sensing flight last Friday are still being processed. No field work is planned for today.
