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 eastward to east-northeastward early in the day and southeastward later in the day.

Recent observations: Over the past few days, seismic energy release has increased slightly, mostly because of minor increases in earthquake sizes and occurrence frequencies of larger quakes. Minor increases in seismicity such as this have occurred repeatedly throughout the eruption and do not indicate any significant change in the character of the eruption. Field crews are out today obtaining new thermal imagery, winterizing the broadband seismometers that have been deployed, conducting routine maintenance on some hydrological warning systems, and measuring rates of water flow from the crater.
