The webcam is a treat together with the ones from Spurr and Veniaminof. One little correction: Katmai did not erupt. It collapsed as Novarupta erupted. It is a common misconception that Katmai erupted.
AUGUSTINE VOLCANO (CAVW#1103-01-)
59.3633°N 153.4333°W, Summit Elevation 4134 ft (1260 m)
Current Level of Concern Color Code: YELLOW
On Friday evening about 3:21 UTC (6:21 PM AST), a sharp increase in seismicity lasting for about 15 minutes occurred and was detected by all of the seismic instruments on the volcano. A lower level of seismicity continued for about one hour, but was detected only at the two seismic stations closest to the summit. It is likely that this event was a small steam explosion. A similar but smaller event occurred at about 6:30 UTC (9:30 PM AST), but no additional events have occurred since then. AVO received a report of steaming at the summit of Augustine from people aboard a fishing boat who first observed the activity at about 19:00 UTC (10:00 AM AST) on Saturday, December 10. Although clear views of the lower half of the volcano were possible by web camera today, clouds obscured the summit from the vantage point of the web camera. AVO has received no additional reports of activity since the report of steaming this morning. There are no indications that an eruption is imminent
