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 westward.

Recent observations: The mountain remains quiet with clear weather conditions and excellent visibility. Lava continues to extrude onto the crater floor with low seismicity, generating occasional rockfalls as talus sloughs off the flanks of the growing dome. Yesterday field crews finished all installations, retrieved some seismometers and winterized others, and everyone arrived back safely, though quite late.
