Scientists Confirm Largest Single Volcano on Earth

The largest volcano on Earth is not in Hawaii, but hidden beneath the western Pacific Ocean and covers an area the size of New Mexico, scientists announced on Thursday. The vast lump of lava is called the Tamu Massif and lies about 1,000 miles east of Japan. It is comparable, though somewhat less voluminous, than the enormous volcano Olympus Mons on Mars.
