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 southeastward early in the day and southward to southwestward later.

Recent observations: Numerous rockfalls continue from the lava dome, but there have been none of the larger (magnitude about 3) earthquakes during the past 24 hours. Successive images from the Sugar Bowl DomeCam show that the lava spine at the north end of the dome continues to extrude at a rate similar to that of the past few weeks. But the rate of rockfall is greater and the altitude of the top of the spine is decreasing. Crews plan to work in the field on Tuesday and Wednesday of this week.
