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 northeastward.

Recent observations: The volcano continues to quietly erupt, slowly extruding spines of solidified lava amidst a background of low-level seismicity. Field crews out yesterday installed new, higher-resolution cameras on the mountain, repositioned seismometers in the crater, installed gas-detection devices near the new dome, and did maintenance on telemetry systems. Crews are out again today doing further maintenance work on instrumentation, installing infrastructure for another still camera, and surveying river channels to document changes caused by the floods in November 2006.
