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 northward at low altitudes and northwestward to northeastward at high altitudes early in the day and northward to southeastward at all altitudes later in the day.

Recent observations: Two notable rockfalls occurred yesterday, one just before noon and another shortly after 3:00 PM. Both produced a dilute ash cloud that rose to a couple of thousand feet above the crater rim. These types of events are common during dome growth. Seismicity remains unchanged with earthquakes occurring on average about every one to two minutes. Yesterday, field crews made airborne gas measurements and finished installing the new tiltmeter.
