Mt. Fitzherbert

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

Recent observations: Small earthquakes accompanying lava dome extrusion continue to occur every 1-2 minutes, punctuated by occasional rockfall signals on seismic records. With clear weather forecasted it is possible that ash clouds from large rockfalls will on occasion be visible. Today, field crews are installing a new tiltmeter on the north side of the 1980- 86 lava dome and continue to harden the GPS network around the volcano. Tomorrow, crews will finish installing the tiltmeter, do a thermal imagery flight and look for a new camera site on the southeast rim of the volcano.
