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-southwestward.

Recent observations: The volcano is clear this morning. Overnight, a pair of rockfalls from the northeast side of the dome (at about 12:04 and 2:08 am) produced bright flashes visible on the JRO VolcanoCam, and this morning deposits from those events are plainly visible. Today, field crews plan to collect rock samples, gather new aerial photographs, and deploy GPS units on the new dome.
