People have discovered several new giant craters in Siberia last summer which drew worldwide interest, launching wild speculation that meteorites or even aliens caused the gaping crevices. Now scientists have found even more of them. In July 2014, reindeer herders discovered a 260 foot wide crater in northern Russia Yamal Peninsula. Later in that month two more craters were discovered in Tazovsky district and Taymyr Peninsula.
Satellite images have revealed at least four more craters and the last one is surrounded by as many as 20 mini craters reported by The Siberian Times. A scientist at Moscow based Oil and gas Research said to The Siberian Times,
“We know now of seven craters in the Arctic area, five are directly on the Yamal Peninsula, one in the north of the Krasnoyarsk region near the Taimyr Peninsula.”
Now two of the craters have turned into lakes, satellite images reveal. A crater called B2 located 6.2 miles south of Bovanenkovo a major gas field in the Yamalo-Nenets autonomous district is now a large lake ringed by more than 20 smaller water-filled craters. Bogoyavlensky thinks there may be many more, he called for further investigation of the craters out of safety concerns for the region.
Although the origin of these craters remains somewhat mysterious many scientist think they were created by explosions of high pressure gas released from melting permafrost or frozen soil due to the warming of the climate. Vladimir Romanovsky a geophysicist who studies permafrost at the University of Alaska Fairbanks said,
‘In my opinion, it definitely relates to warming and permafrost.”
