Before this discovery, scientists had known of the basalt and limestone rocks that exist there but weren’t sure how they got there. What they did know was that a volcano on the island of Fogo had crumbled and fallen into the ocean. The tsunami they had discovered was so powerful that it propelled elephant-sized boulders over 600-feet through the water and air and onto the plateau of the island.

The discovery of this mega-tsunami through studying the huge boulders provides additional information and explanation that legitimatize the possibility of other past disasters. Forty-nine boulders weighing up to 700 tons were lifted to their current position by a gargantuan tsunami.
