When the active volcano Tolbachik erupts in the east of Russia, lava got in contact with the snow. The view of this interesting encounter of these elements reveals amazingly different ways of interaction, which depend mainly on the type of lava.
Ben Edwards of college “Dickinson” in Carlisle, Pennsylvania, and his colleagues observed lava during the eruption of the volcano in the winter of 2013 year. Dug a pits for observation before the lava to watch how it moves through the snow. As you can see on the video, the lava progressing through solid snow. The lava forms thick “tongue” and can cross a hundred to a thousand meters.
On the other hand, while the lava is progressing, front part moves over into the snow up to two meters below the surface. The lava spread beneath the snow, causing steam to rise while is mixing with water. It also pushes up the snow, making snow domes that turn into blocks.
The only phenomenon that occurs as a result, can serve as an example for the identification of ancient lava that came in contact with the snow, revealing more about the distant past of our country – and even some details of ice history on Mars.
