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 eastward early in the day and northeastward later.

Recent observations: A low layer of clouds obscures views of the lava dome in both the JRO VolcanoCam and the USGS DomeCam. Seismicity remains unchanged over the past few days, but the rate of motion of a GPS unit on the north end of the new dome has slowed slightly; it continues to creep eastward and northward at a rate of several inches per day, but it is no longer rising vertically. The lava spine, however, continues to grow. Yesterday, clouds prevented a field crew from making measurements of gases. If the cloud layer breaks sufficiently today, that crew may try again to make the measurements.
