A Japanese submarine discovered the world's largest underwater lava flow near Peru, stretching 40 kilometers along the East Pacific Ridge. The research team used the Shinkai submersible, capable of diving 6500 meters, to survey the area. The submarine is equipped with advanced cameras and robotic arms for specimen collection. The lava flow's location, far from seismic plate edges, challenges existing theories on volcanic activity and continental drift.
