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 primarily to the northeast.

Recent observations: The clear weather continues to offer a good view into the crater today. Seismic activity continues at a low level. Many of the events recorded by crater seismic monitors are due to rockfalls and glacier activity associated with continued slow dome growth. Yesterday was a successful field day for working on monitoring sites, making field investigations, and placing two GPS spiders.
