Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds that rise above the crater rim today would drift northward to north-northeastward.

Recent observations: The volcano is visible on the VolcanoCam this morning below high clouds. The crater is clear with only a small steam plume rising off the new lava dome. Since last Sunday's explosion, the GPS stations on the old lava dome have moved northward several inches and the rate of seismicity has increased slightly. Such changes have been detected in the past and define broad cycles of slightly higher and lower rates of activity.
