A newly discovered volcano replaces Hawaii's Mauna Loa as Earth's largest. Called Tamu Massif, the massive volcano sits 6,500 feet under water in the northwest Pacific ocean. The volcano is 400 miles wide and stands 2.5 miles tall. The mountain is part of an oceanic plateau called the Shatsky Rise.
Geologist believe Tamu Massif last erupted some 144 million years ago. To view a 3-D map and read more about the discovery, click: www.livescience.com/39447-biggest-volcano-earth-found.html
