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 northeastward.

Recent observations: The lava spine continues to grow, accompanied periodically by rockfalls and moderate-size rock avalanches. At night incandescence associated with hot rockfalls may be visible. The west part of the new dome continues to deform as fresh lava extrudes from the vent. Seisimicity remains at levels typical of the past few days. Large rockfalls and avalanches caused by the growing spine can generate ash clouds that rise above the crater rim.
