With a strong explosion in 1831, the average annual temperatures of the Earth began to change. It caused a decrease in the northern hemisphere. About 200 years have passed. It was mystery which volcano caused this change. Until a few months ago.
Earlier this year, a study published in the National Academy of Sciences of the National Sciences, indicating that the Zavaritskii volcano in Simuşir, one of the Kuril Islands, could be the sought -after volcano.
There are 3 more volcanoes in this region, which causes tension between Russia and Japan: Milna, Prevo and Uratman.
The volcanic island was once a secret Soviet military base. It was even used as the base of Soviet nuclear submarines until recently. This ended in 1994 and the island became deserted.
Looking at the satellite photographs of the island, 4 volcanoes are listed in line.
Milan, the highest volcano, exploded in 1914. 1540 meters high. Then the 1360 meters high prevo comes. Uratman, which is 678 meters high, is third. Uratman has not shown any signs of explosion in the last 12 thousand years. The Gulf of Brouton around him was used as a shelter of nuclear submarines.
The fourth and lowest volcano is 624 meters Zavaritskii. The last volcano, which exploded in 1957, caused the world to cool 200 years ago.
