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 westward to northward at low altitudes and eastward to southeastward at higher altitudes. Wind speeds are forecast to be low so any ash clouds would move away from the volcano sluggishly.

Recent observations: Field crews got an early start this morning. One crew is currently installing another tiltmeter on the old lava dome. Others are getting ready to deploy an additional camera near the northwest crater mouth, recover and deploy seismic and GPS spiders on the new lava dome, and repair some telemetry equipment. Views from the camera installed on the south crater rim show continued growth of the active part of the new lava dome over the past three weeks.
