Activity at Pavlof, Alaska

For the third time this century, Alaska’s Pavlof Volcano is erupting. The Alaska Volcano Observatory first detected earthquakes associated with the movement of magma and heat at Pavlof’s summit on May 13, 2013.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite captured this true-color image of a small ash plume and lava flow on the morning of May 14. The red “hotspot” marks where the thermal detectors picked up temperatures higher than background, and, in this case, indicates most likely indicates hot lava at the site of the eruption.
