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 north to northeastward.

Recent observations: Clouds partly obscure the volcano today although this morning the crater has been mostly clear. Although seismicity has been relatively quiet lately, recent observations of the dome indicate that an actively moving slab of solidified lava continues to extrude at a rate of about 2 meters per day, and a GPS unit on the western margin of the dome bounded by that slab continues to migrate westward at about a meter per day.
