8. Tamu Massif
Tamu Massif is considered the largest volcano in the world, surprisingly it is located deep under the Pacific Ocean. "The newly discovered volcano is called Tamu Massif. It surpasses the volcano holding the world's largest record, Mauna Loa in Hawaii, USA. Tamu Massif is only 25% smaller than Olympus Mons on Mars , the largest volcano in the solar system," said William Sager, a geographer from the University of Houston, leader of the research team.
Tamu volcano is 650km wide but only about 4km high, with a volume of about 2.5 million square kilometers. Tamu was active about 144 million years ago, at the beginning of the Cretaceous period. This volcano has an area larger than England. Like other volcanoes, Tamu Massif operates in a central cone structure, from which lava erupts onto wide slopes. Seismic surveys and lava samples collected from research vessels several years ago have proven this.
Lying quietly beneath the immense ocean waves, the Tamu Massif volcano is like a giant secret of the ocean, sleeping peacefully for millions of years. Making everything around it seem small, this is one of the largest and most spectacular volcanic clusters the world has ever known.
