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 northward to westward at low altitudes and northeastward at higher altitudes.

Recent observations: Crews are on their way to the field to make thermal observations of the growing lava dome, to continue GPS measurements of a regional network of benchmarks, and to complete installation of a new time-lapse camera on the northwest crater rim. Eruptive conditions remain unchanged as lava continues to extrude slowly.
