A volcano of the size of New Mexico or the British Isles has been identified under the Pacific Ocean, about 1,000 miles (1,600 kilometers) east of Japan, making it the world’s largest volcano on Earth and also one of the largest in the solar system.
Called Tamu Massif, the giant shield volcano had been thought to be a composite of smaller structures, but now scientists say they must rethink long-held beliefs about marine geology.
Scientists studying the ocean floor were shocked when they stumbled upon what they believe is the world’s largest volcano.
Gigantic Tamu Massif sits one mile deep beneath the Pacific ocean several hundred miles away from Japan.
The site was believed to be made up several different volcanoes but now scientists discovered it is in fact one huge supervolcano that erupted some 145 million years ago.
Spanning some 120,000 square miles, Tamu Massif is a similar size to the British Isles and is now thought to be the second largest volcano in our solar system – behind Olympus Mons on Mars.
It is believed to sink some 18 miles deep into the Earth’s crust.
You can rest easy however, as researchers believe it is inactive and it is ‘unlikely’ to erupt again in the near future.Tamu Massif is a single, immense volcano, constructed from massive lava flows that emanated from the volcano centre to form a broad, shield-like shape.It could be the largest single volcano on Earth and that it is comparable in size to the largest volcano in the Solar System, Olympus Mons on Mars.”
Previously, the largest volcano on Earth was Mauna Loa in Hawaii.
