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 south-southwestward in the morning then gradually shift to an east-southeastward trajectory in the afternoon.

Recent observations: Intermittent views of the crater under partly cloudy skies reveal the volcano emitting a steam plume from the actively growing lava dome. Overnight glow visible from the USFS VolcanoCam along with our instrumental records clearly show that lava continues to extrude and grow the dome. Seismicity continues its ongoing procession of tiny “drumbeat” earthquakes every several minutes, punctuated by the occasional larger earthquake. Overall, the rate of seismic energy release remains relatively low, and other monitoring data are within the range of their typical recent values.
