Scientists continue to keep a close eye on Alaska's Mount Redoubt volcano. The 24/7 monitoring is intended to make sure aviators and residents of the area, including nearby Anchorage, have plenty of time to prepare if the volcano repeats its destructive eruption of 1989-90.
The Alaska Volcano Observatory has mounted a webcam on Redoubt's north flank, at about 7.5 miles from the crater at the summit. Observers now have noted some new muddy debris flow along the glacier located on Redoubt's downslope.

Several volcanic earthquakes are occuring every hour. The USGS has a website offering information about ash fall and how to keep yourself safe.
Redoubt's last explosion coated Anchorage and nearby areas with ash, disrupted international air traffic, and days later, damaged airplanes in Texas.
