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 northeast.

Recent observations: The dome's active spine 7 grows sluggishly. Lacking a GPS receiver on the spine or fixed sites that might be surveyed, we track 7's incremental progress only by assembling sequential camera images into time-lapse sequences. Seismicity remains low, and yesterday's early-morning shallow M2.9 earthquake is now a fading highlight among the chatter of periodic rockfall and glaciogenic seismicity.
