Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds rising above the crater rim today would drift northeastward.

Recent observations: Lava extrusion continues marked by frequent small drumbeat earthquakes and occasional larger ones. Views this morning from a camera on the south crater rim show that the narrow pointed top of the spine is still largely intact and was not toppled by earthquakes up to magnitude 3.3 over the weekend. Small rockfalls continue to be recorded in seismic records and show up in camera views. Such events produce small ash clouds that sometimes are large enough to rise above the crater rim and drift off downwind.
