Re: [Geology2] Volcano News 1-23-2013



Nope, Vic. Didn't miss it. And somehow, I managed to not post the following yesterday morning. Doh. Not enough coffee, is all I can say. :-)

Russia's Kamchatka Peninsula has the highest concentration of active volcanoes on Earth. Separated by only 180 kilometers (110 miles), Shiveluch, Bezymianny, Tolbachik, and Kizimen were all erupting simultaneously on January 11, 2013.

The activity of these four volcanoes was captured during a single orbit by the Advanced Spaceborne Thermal Emission and Reflection Radiometer on NASA's Terra satellite. These four false-color (near infrared, red, and green) images show Shiveluch, Bezymianny, Plotsky-Tolbachik, and Kizimen in detail.

The Shiveluch and Bezymianny eruptions are both characterized by a growing lava dome—thick, pasty lava that forms a mound as it is extruded. Tolbachik, one of the few shield volcanoes on Kamchatka, is erupting in a dramatically different manner. The thin, runny lava flows easily, forming low and broad flows similar to those in Hawai'i. In this image the lava remains hot enough to glow in near-infrared light.

Kizimen's lava is not as viscous as that at Shiveluch and Bezymianny, but not as fluid as Tolbachik's. The intermediate lava forms thick, blocky flows bordered by tall levees. Rocks and ash frequently fall from Kizimen's summit and the fresh lava flow on its eastern flank, creating dark, fan-shaped debris deposits.

Lin, you totally missed the news of whats happening in Russia.


There are three volcano's in intense eruption in their NE.

I had three separate articles on these i was going to forward you Lin for your comment and I lost it all when my wife used an iPad to read our email.
That bloody iCloud automatically removes them from all our other  devices when she deletes messages that we both have read.


The sheer intensity of the eruptions in the same general area surprised me, probably the Russians too.
