Exploring the Depths: Uncovering the World's Largest Underwater Lava Flow

A Japanese submarine discovered the world's largest underwater lava flow near Peru, stretching 40 km along the East Pacific Ridge. The Shinkai submersible, capable of reaching depths of 6500 meters, aided the research team. Equipped with high vision cameras and robotic arms, it can collect specimens during nine-hour missions. The lava flow, far from seismic plate edges, challenges current understanding of volcanic activity and continental drift.
