Scientists say that they have discovered the single largest volcano in the world, a dead colossus deep beneath the Pacific waves. A team writing in the journal Nature Geoscience says the 310,000 sq km (119,000 sq mi) Tamu Massif is comparable in size to Mars' vast Olympus Mons volcano-the largest in the Solar System.
