Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that any ash clouds rising above the crater rim today would drift south early in the day and south-southeast later in the day.

Recent observations: The crater is partly obscured by low clouds this morning. Volcano activity continues with on-going seismicity, deformation, and rockfalls from the crater walls and growing dome. Last week, crews installed a new GPS spider on spine 4 of the new lava dome, decommissioned the Yellow Rock seismic station, which was threatened by rock and ice fall from the advancing west lobe of the Crater Glacier, and removed no-longer-serviceable equipment from a monitoring site on the 1980-86 lava dome. There have been no significant changes in conditions over the last 24 hours.
