Something Is Causing Siberia’s Tundra to Literally Bubble Underground

Now, the frozen tundra on Siberia’s remote Belyy Island is home to the region’s newest aberration: eerie, rippling, underground bubbles.

In a video released today by the Siberian Times, researchers Alexander Sokolov and Dorothee Ehrich investigate a seemingly nondescript tract of grass that turns out to be a large, concealed pocket of… something. 

Kind of like a trampoline, the subterranean bubble forcibly undulates as Sokolov puts pressure on one side using his foot. According to the Russian scientists, a total of 15 blister-like patches were discovered on the island.
