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 eastward to southeastward.

Recent observations: No significant changes in seismicity or ground deformation have been detected in the past 24 hours, and seismicity remains generally low. Last Friday’s gas-sensing flight detected typically low values of volcanic gases, but final results await further analysis. Another clear day permits good views of the growing lava dome with occasional rockfalls producing small clouds of ash.
