September 6, 2013. Recently, geologists from the University of Houston in the bottom of the Pacific Ocean was discovered the largest volcano on Earth, which is part of the oceanic plateau Shatsky, a 1 600 km to the south-east of Japan. The volcano is called Tam and completely submerged in the water.
Tama area mountain is 310 thousand km ², which is comparable to the size of the British Isles. Undertake a detailed measurements, the experts concluded that the Tamu, fully formed from lava that can safely assign the title of the largest volcano on the planet and one of the largest in the Solar System. He is only 20% less than a Martian volcano Olympus, the largest volcano in the mountains, our system.
Fortunately for Japan and other inhabited islands of this area of the ocean, Tam is one of the extinct volcanoes of the thyroid, a long time showed no signs of activity. Its internal structure continues to be studied, attempts to determine the origin of the mountain, which appeared about 145 million years ago.
By the way, the area of the largest terrestrial volcano, Mauna Loa in Hawaii, is 5,200 km ², and the name Tamu name is an acronym for the University of Texas (Texas A & M University), where he taught previously Professor W. Sager, who studies Tamu.
