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 east-northeastward at low elevations, and east to east-southeastward at high elevations.

Recent observations: Clouds continue to obscure the mountain this morning. Heavy snowfall has blanketed the mountain and is causing episodic and temporary disruptions of transmitted seismic signals. The monitoring network is highly redundant, however, and such outages do not significantly degrade detection of earthquakes. The steady background of small crater earthquakes and slow westward movement (about one meter per day) of a GPS station on the active dome continue, and indicate ongoing extrusion of solidified lava.
