Feb 24, 2006, Alaska Volcano Observatory Some of you know I have been following the activity of Augustine Volcano in Alaska, a 4134 ft high conical shaped stratovolcano located in southern Cook Inlet about 70 miles south west of Homer and 180 miles south west of Anchorage. It has been very interesting to watch and learn from - especially since there is NO danger to people on a totally uninhabited island.

Historically, Augustine is the most active volcano in the Cook Inlet region with significant eruptions in 1812, 1883, 1908, 1935, 1963-64, 1976, and 1986. These eruptions were primarily explosive events that produced volcanic ash clouds (to 30,000-40,000 feet above sea level), ash fall, pyroclasic flows, and and lava domes or flows.
They have a image library that dates back to 1896 - and especially chronicles the most eruptive period that recently occurred last Dec and this January. It is now in code orange and has been in the most active code red earlier this year. It is being monitored closely by the Alaska Volcano Observatory and updated 2x daily (Hourly when it was in code red), and weekly. You can see live webcams from the island and view seismic data from the webicorder. There are so many recording instruments on the island and the scientists at the University of Fairbanks Geological Institute are sharing their findings with the world on this website.
