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 would drift eastward.

Recent observations: The mountain is presently enveloped in a strong winter storm that is depositing significant amounts of snowfall. As a result, all views are obscured. Our instrumental signals indicate that the procession of small earthquakes continues, punctuated by occasional larger quakes that may be related to rockfall activity. The GPS receiver on the new dome shows that new lava emerging from the vent is still plowing west-northwestward at about a meter per day.
