" This event dramatically reshaped the coastline and provided scientists with a rare opportunity to study active volcanic construction. The volcano itself is a massive stratovolcano built upon the seafloor, with its summit currently located approximately 200 meters below sea level.
This generates magma that rises through the crust, eventually reaching the seafloor. Its location along the boundary where the Pacific Plate dives beneath the Philippine Sea Plate creates the conditions for its persistent activity.
