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 broadly southwestward at low elevations and southward to southeastward at higher elevations.

Recent observations: Another large (M3.2) earthquake occurred at 6:10pm yesterday. The quake generated a small rockfall and associated ash plume. Images from a camera at the mouth of the crater show that the new lava spine continues to emerge from the ground at a rate of several meters per day. To clarify a point made yesterday, although measured volcanic gases are down slightly since the last measurement in July, the change is insignificant. Thus there has been no substantive change in levels of gases recently emitted by the volcano.
