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.

Recent observations: Outages to a satellite communications link continue to plague receipt of data streams from some of the crater seismic and deformation instrumentation. However, data streams from key seismic and deformation stations continue to be received, and those instruments show no significant changes in seismic or deformation trends of recent weeks. With good weather expected to hold, field crews have plans this week to install a new tiltmeter, deploy a new GPS instrument and new cameras, retrieve and repair a seismometer, and collect new aerial photography and thermal imagery.
