Mt. Fitzherbert

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 chiefly drift west-northwestward.

Recent observations: The volcano is shrouded in clouds this morning. New instrumentation packages installed on the dome Friday are transmitting data that will be used to more closely track movement of the north end of the new dome. Seismicity suggests that small rockfalls are occurring from the dome. Such rockfalls may generate ash plumes that drift over the crater rim.
