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.

Recent observations: We scientists continue to watch and wait, our armor red and thin with rust, our souls from sorrow freed. A network of 30s Guralp broadband seismometers and single component instruments record the occasional small earthquake and periodic rockfall, stainless steel borehole tiltmeters buried within the dacite debris of the crater floor reveal a 30-60 minute pulsation as lava is pushed up and out of the vent, and a network of geodetic grade L1/L2 GPS instruments linked to our satellite constellation track the velocity of the mountain and crater floor relative to North America in an ITRF2000 reference frame. We long for change, for action, to charge into space, but quiet did quiet remain (with apologies to Walter de la Mare).
