Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that any ash clouds rising above the crater rim today would drift southeast.

Recent observations: High winds have saturated the seismometers closest to the new dome as a winter storm develops. The result has been a small spike in the real-time seismic amplitude measurements this morning, albeit in the absence of notable volcanic activity. Our in-crater tiltmeter shows only the sparse small tilt events related to deformation in the shallow volcanic conduit, currently the main indicator that dome lava is extruding sluggishly and quietly. Videocam observations have been obscured by the weather during the previous 12 hours.
