The ocean has erased entire civilizations, and history has buried the evidence. From the volcanic wave that may have inspired the Atlantis myth to the ghost boats that washed up on American shores decades later, these 10 devastating tsunamis did not just kill people — they deleted empires, rewrote borders, and changed the course of human history overnight.

Some were predicted by ancient stone markers that nobody listened to. Others left no bodies, no survivors, and no explanation. Every single one of them left a world that could never go back to what it was before.
