Eruption of such a volcano could be ten thousand times more powerful than that of an ordinary one
Scientists have discovered caldera of an ancient supervolcano at Kamchatka. "The eruption of the Kamchatka supervolcano took place more than about a million and a half years ago." Now the volcano has "cooled off," so some specialists say it would be incorrect to speak of any possibility of new eruptions. But the eruption of such a volcano could be ten thousand times more powerful than that of an ordinary one. The discovered caldera is a giant oval 35 kilometres long. The caldera is stretched between the head of the Paratunka River and Banniye hot springs. Scientists suppose that these particular springs might be heated by the warmth of the ancient super-volcano. The Yellowstone Caldera measures about 55 by 72 kilometres. The last supervolcano eruption occurred 74 thousand years ago in the region where Sumatra is located today. Then the average temperature in the Northern Hemisphere fell 21 degrees Centigrade.
