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 early and east-northeastward later.

Recent observations: Winds are again stirring dust and ash in the crater and creating a stream of dust that is being carried northeast of the volcano. Seismicity remains at very low levels, and camera imagery shows that the central part of the new dome continues to sag and slump as the newest spine continues to grow. Today, crews are in the field measuring streamflow from the crater, servicing mudflow warning sensors, retrieving seismic data from self-recording seismometers, and continuing with geologic mapping of the volcano.
