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 northwestward to northeastward at low elevations and eastward at high elevations early in the day, then northward to north-northeastward later in the day.

Recent observations: Clear conditions show the volcano emitting a moderate steam plume this morning. There have been no significant changes in seismicity or deformation over the past several days. A glitch following a server upgrade at the PNSN site yesterday caused a temporary outage of the display of seismic records on the web. This glitch affected only the display, and not the collection, of seismic data. Results of a gas flight on Tuesday show that SO₂, CO₂, and H₂S emissions were similar to those measured during the previous flight a few weeks ago and remain very low. Analysis of recent camera images indicates that the dome continues to extrude at a linear rate of about 2 to 3 meters per day (6 to 10 feet per day).
