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-northeastward early in the day and eastward later.

Recent observations: Poor weather prevents visual contact with the volcano, and stormy weather is forecast for the next few days. Yesterday, field crews were able to conduct a thermal-imaging flight, complete repairs to a voice communication system, and bring a seismic communication link back online. However, lingering fog in town and continuous bursts of small ash clouds from the base of the lava dome prevented crews from installing a new spyder on the lava dome and measuring volcanic gases. For the week, crews successfully installed, repaired, and maintained GPS sites, seismic and voice communication links, and remote field cameras, and made critical visual observations.
