Most of the volcanic eruptions on planet Earth happen in the ocean! In 2009, marine scientists discovered the deepest ocean eruption ever found in the West Mata volcano in the Pacific Ocean. The kind of lava that it was spewing, called boninite lava, is some of the hottest lava on Earth and you can see some of the explosions of molten rock in this video. Scientists compare it to a spectacular underwater fireworks display at nearly 4,000 feet deep. They also found shrimp living near the volcano's most active areas. This glimpse into undersea volcanic activity and life helps scientists understand how processes deep within Earth shape the surface and how life adapts to some of the harshest conditions on our planet.
