Amazing images of Pavlof Volcano erupting in Alaska!

These pictures of Pavlof Volcano in Alaska were not taken by satellite, but rather were taken by astronauts living on board the International Space Station on May 18, 2013. Pavlof volcano is located in the Aleutian Islands about 625 miles southwest of Anchorage, Alaska.

Activity in Kamchatka

Four active volcanoes located on the Kamchatka Peninsula in Russia were caught erupting simultaneously on January 11, 2013! This is no real suprise as the Kamchatka Peninsula has the highest concentration of active volcanoes on Earth, but to have images of Shiveluch, Bezymianny, Plosky-Tolbachik, and Kizimen volanoes (see map below) erupting at the same time is quite spectacular. The activity of the four volcanoes was captured by the Advanced Spaceborne Thermal Emission and Reflection Radiometer on NASA's Terra satellite during a single orbit. An amazing satellite photo of Tolbachik volcano is shown below, which is one of the few shield volcanoes on Kamchatka. The photo shows the thin, runny lava flows forming low and broad flows much like those formed in Hawai'i and the hot lava actually glowing in near-infrared light. The image above is of a lava fountaining on Polsky Tolbachik courtesy of Kamchatka Volcanic Eruption Response Team (KVERT). 

Activity at Tungurahua Volcano, Ecuador

 

There has been an increase in activity at Tungurahua volcano, a steep-sided, 16,479-foot stratovolcano located in Ecuador in August 2012. The volcano is one of Ecuador's most active volcanoes (the volcano has erupted periodically since 1999) and sits roughly 140 km south of the capital city of Quito. The most recent avticity at Tungurahua included 16 large explosions on August 20th. As nearby villagers heard the explosions, avalanches of incandescent material rolled 1.5 km down the flanks of the volcano during that evening.
