Scientists have identified the largest volcano on earth, beneath the Pacific Ocean roughly half way between Japan and the Hawaiian Islands. The giant shield volcano has been named Tamu Massif and it is roughly, 100,000 square miles or approximately the size of the British Isles or New mexico. Mauna Loa, on the island of Hawaii, now the second largest volcano on earth covers, by comparison, 2,000 square miles.
Underwater volcano is Earth’s biggest
<The megavolcano has been inactive for some 140 million years. But its very existence will help geophysicists to set limits on how much magma can be stored in Earth’s crust and pour out onto the surface. It also shows that Earth can produce volcanoes on par with Olympus Mons on Mars, which, at 625 kilometres across, was until now the biggest volcano known in the Solar System.
