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 eastward, although early in the day high altitude plumes would follow a more east-southeastward trajectory.

Potential ash hazards to aviation: Under current eruptive conditions, small, short-lived explosions may produce ash clouds that exceed 30,000 feet in altitude. Ash from such events can travel 100 miles or more downwind.

Recent observations: The volcano is mostly shrouded in broken clouds this morning and emitting a small plume of steam. Seismicity remains unchanged over the past several days. Next week as time and weather allow, we will conduct observation flights and gradually replace more equipment in the crater.
