Mt. Fitzherbert

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 south-southeastward early in the day and southeastward later.

Recent observations: Once the lowland clouds dissipate, we may be able to see a vapor plume drifting southeastward over the crater rim. The level of eruptive activity remains unchanged from that of recent weeks. A reanalysis of late September repeat photographs of the active part of the new lava dome indicates that points on the dome are moving northwestward and upward at about 5.5 meters (18 feet) per day as extrusion continues.
