Scientist find the largest volcano on Earth - Sara Múnera B.



SCIENTIST FIND THE LARGEST VOLCANO ON EARTH

A volcano that could be the biggest on the Solar System was found in Japan at the bottom of the Pacific Ocean by Houston University scientists.

A volcano under water was identified by Huston University scientists in the Pacific Ocean about 1.600 kilometers at the east of Japan.

The Tamu Massif was discovered after several years of exploration. It was made by the eruption of other volcanoes and it has the same size than New Mexico (United States), making it the biggest volcano on Earth. It could be also the biggest of its type in the Solar System, next to the Olympus Mont in Mars and Rea Silvia in Vesta asteroid.

The Tamu Massif is not only the biggest but the oldest volcano ever discovered. Its structure developed from a chain of mountains that cover the ocean bed, and it has an area of 195.000 square kilometers. Even the largest active volcano of the world, the Mauna Loa in Hawai, represents only the 2% of the Tamu Massif.

This volcano erupted for a few million years during the early Cretaceous period, about 144 million years ago, and it has been extinct since then. However, there’s a permanent debate on scientific community because each group of them has different theories to explain its emergence.
