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 southward to south-southeastward.

Recent observations: Seismicity at the volcano remains very low, and the lava dome continues to shed rockfalls. Tomorrow, field crews plan to continue mapping the geology of the volcano, conduct routine servicing of gaging stations and mudflow warning systems, and retrieve data from an array of broadband seismometers deployed at the mountain.
