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 south-southeastward.

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 clear this morning and a minor amount of steam is rising from several spots around the growing lava dome. Seismicity remains unchanged from levels of the past few days. Field work this week awaits the completion of new seismometers and GPS units to replace those lost during last week's explosion.
