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 to the east-southeast early in the day and to the east later in the day.

Recent observations: The snowy base of the volcano to the crater breach is visible in the JRO volcano cam, with the upper flanks obscured by clouds. The recent storm has affected the telemetry of many of our seismic stations, but those operating show very few earthquakes. Small perturbations in deformation from our in-crater tiltmeters indicate that slow extrusion of the lava dome continues.
