NASA Earth Observatory: Klyuchevskaya Volcano eruption

After a respite of less than a month, Klyuchevskaya Volcano resumed erupting in late November 2010.

The Global Volcanism Program reported several ash plumes that rose up to 7.9 kilometers (26,000 feet) above sea level from November 25–29.

According to the Kamchatka Volcanic Eruption Response Team (KVERT) seismicity was “slightly above background levels” on November 26th and 27th, and they reported observations of strombolian activity on December 1st and 2nd.

A plume of ash, steam, and other volcanic gases streamed from Klyuchevskaya on December 4, 2010, visible in this natural-color image acquired by the Advanced Land Imager (ALI) aboard the Earth Observing-1 (EO-1) satellite.

In the large image, a much smaller plume is visible above neighboring Bezymianny Volcano.
