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 eastward in the morning, changing to east-southeast by afternoon.

Recent observations: For the past 24 hours, the winter 2008 eruption mantra seems unchanged from previous updates: snowy weather allows few or no visual observations of the new dome, but sparse seismicity recorded by an in-crater seismometer, coincident with small tilt events every few hours on the NDM tiltmeter, are evidence that the active lava spine budges upward in miniscule nonhazardous pulses.
