Mixed results for the Aleutians

The folks up in Alaska have a lot to watch these days in the Aleutians, with three volcanoes erupting right now. Just a quick update on the current activity:   Kasatochi: The eruption that started Thursday and produced 45,000 foot ash columns has quieted by Saturday, but there are still moderate (M=5) earthquakes being recorded…

Kasatochi erupts

Just a quick update if you haven’t been following the discussion: Kasatochi volcano in the Aleutians is now listed in “Red Alert” as it is erupting (see image above). Not many details beyond the typical description of ash columns, in this case reaching 45,000 feet, which is a pretty decent height. The Coast Guard warns…

The Okmok Caldera eruption is still going on, almost a month after it started. The latest USGS/SI Weekly Report states:    Strong volcanic tremor on 2 August prompted AVO  to raise the Volcano Alert Level to Warning and the Aviation Color Code to Red.

Currently, both Okmok and Cleveland are erupting, and now AVO has issued a warning about Kasatochi Volcano on the island of the same name (~100 kilometers east of Adak,…

Waiting game at Chaiten

So, August rolls in and who would have thought in early May we’d still be talking about the Chaiten eruption with such intensity. Jorge Munoz of the SERNAGEOMIN is wondering whether the current eruptive activity and seismicity at Chaiten is a precursor to the end of the “first cycle” (as he calls it) of activity…
