Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that any ash clouds rising above the crater rim today would drift eastward to east-southeastward.

Recent observations: Clear weather affords good views of the volcano today, although rockfalls and winds in the crater are creating a dusty haze that inhibits visibility. At 9:46am an earthquake and associated rockfall from the dome produced a very visible dust plume that rose above the crater rim. Other such events could happen again producing plumes visible from the metropolitan area. Imagery shows that extrusion of lava that is building the dome continues. Overall, seismicity at the mountain is low, and there have been no significant changes in seismicity or ground deformation in the past 24 hours.
