In today’s Science News, scientists have discovered one of the largest known volcanoes in our Solar System under the Pacific Ocean, about 1,000 miles east of Japan. That’s right, the new volcano, named Tamu Massif, is not only the largest volcano on Earth (by far), it is one of the largest in the Solar System. Quite a discovery, right here at home!

Tamu Massif covers an area of about 120,000 square miles - about the size of the state of New Mexico. That is 60 times bigger than Hawaii’s Mauna Loa, which up until now we had thought was the largest volcano on Earth.

Fortunately, the huge volcano is no longer active, but scientists are eager to study it and try to learn more about how these mega volcanoes form.

There is much that we are still learning, about Earth’s geology and about animals, under the oceans that cover 70% of the surface of our planet.
