Volcanic Eruption Reshaped Earth's Plate | Science News

Scientists uncovered how Earth’s biggest volcanic event—110 to 120 million years ago—didn’t just build the massive Ontong Java Plateau, but also rewired the oceanic plate beneath it. Using seismic waves, researchers found a layered, magma-scarred foundation with vertical tunnels called dikes, where magma didn’t just flow but chemically altered the rock. This colossal eruption, likely fueled by a superheated mantle plume, may have triggered global environmental shifts and mass extinctions. The discovery reveals that giant volcanic events reshape not just the surface, but the deep, enduring structure of our planet.
