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 east-southeastward.

Recent observations: Seismicity and ground deformation continue at rates similar to those of the past few weeks. Several crews are headed to the field to make visual observations, to collect samples, to place a GPS-spider on the growing lava dome, and to perform several maintenance chores to seismic and radio-telemetry sites.
