Scientists studying the ocean floor were shocked when they stumbled
upon what they believe is the world's largest volcano. A megavolcano found at
the bottom of the Pacific Ocean is being reported as the largest single volcano
on Earth.
Tamu Massif, as the megavolcano is called, may be as
voluminous as Olympus Mons on Mars, which is regarded as the Solar System’s
largest known volcano.
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 as huge amounts of magma flowed onto
the ocean floor at a point where three microplates of Earth’s crust meet.
- The 400-mile wide Tamu Massif volcano sits 1,000 miles east of Japan
- It was originally believed to be part of the Shatsky Rise plate
