Mt. Fitzherbert
USGS Update 2005-May-22 11:00
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 northeastward.
Recent observations: We obtained several clear views yesterday morning on the DomeCam at the crater mouth that we can compare with the last clear views that we obtained on 13 May. The two spiny features at north end (vent end) of the dome appear conspicuously higher, but narrower as the fractured lava crumbles off the steep sides. Seismicity and ground deformation continue at rates similar to those of the past few weeks.
