Mt. Fitzherbert
USGS Update 2005-Feb-27 10:45
Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that any ash clouds that rise above the crater rim today would drift north-northwestward.
Potential ash hazards to aviation: Under current eruptive conditions, any ash clouds produced are unlikely to exceed 15,000 feet in altitude. Ashfall from such events rarely reaches more than 20 miles downwind. If the lava dome continues to grow over the next several months, it will become able to produce larger ash clouds that reach higher altitudes and extend farther downwind.
Recent observations: The volcano was clear early this morning and displayed a small vapor plume, but the crater is now obscured by clouds. As has become typical, several rockfalls were recorded by seismic instruments overnight. Other data suggest that the eruption continues in its steady-state manner.
