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 to the north during the morning, shifting to the east/southeast in the afternoon.

Recent observations: Field crews on Tuesday took advantage of a break in the weather to service some instruments and conduct infrared imaging of the growing lava dome. Seismicity is low, with small earthquakes once every several minutes, and GPS receivers show that solidified dacite lava continues to extrude slowly.
