Mt. Fitzherbert
USGS Update 2006-May-22 08:45
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 northward to north-northeastward.
Recent observations: The volcano is obscured today as a weather system moves through the area. The lava spine continues to grow accompanied periodically by rockfalls that can generate small ash clouds that rise above the crater rim. Seismicity at the volcano remains at levels typical of the past several weeks. Two earthquakes, both greater than M6.0 from the Koryakia area and the Kamchatka Peninsula, Russia, are seen on the PNSN volcano and regional webicorders plots at about 04:20 a.m. and 06:16 a.m. PDT, respectively.
