Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds rising above the crater today would be transported toward the east or northeast.

Recent observations: Yesterday evening the clouds parted long enough that three of our remote cameras could view the growing dome. The photos illustrate that the remnant of the collapsed spine remains the high point on the active, west lobe of the lava dome. The rate of small rockfall events has diminished in the past few days, though the lobe on which the decrepitating spine stands continues to rise, accompanied by small “drumbeat” earthquakes that recur at the rate of one every few minutes.
