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 east-northeastward.

Recent observations: There have been no significant changes in seismicity or ground deformation during the past few days. One consequence of the current westward growth of the new lava dome and its broad apron of rock debris is that the west arm of the glacier, which thus far has been much less severely affected than the east arm, is now being pushed northwestward and the glacier surface is beginning to rise and fracture.
