Lava continues to erupt slowly at Great Sitkin Volcano, adding to a thick lava flow that fills most of the summit crater. Small earthquakes associated with the ongoing lava eruption continue. Nothing unusual was observed in mostly cloudy satellite and web camera imagery.
Alaska contains about 140 volcanoes and volcanic fields active within the last 2.6 million years (the Quaternary). About 90 of these volcanoes have been active within the last 11,000 years (the Holocene), and more than 50 have been very recently active, within the last 300 years or so.
For a vast trove of information about Alaska volcanoes, check out the Alaska Volcano Observatory. This easy-to-navigate website has current status of erupting volcanoes plus an atlas with maps, photographs, webcams , eruption history, scientific research and more.
Alaska contains over 130 volcanoes and volcanic fields that have been active within the last two million years. Of these volcanoes, about 90 have been active within the last 10,000 years (and might be expected to erupt again), and more than 50 have been active within historical time (since about 1760).
