Why Do Earthquakes Happen Under the Sea?

Examples

  1. A big underwater earthquake caused by two plates sliding past each other creates a wave that travels across the ocean.
  2. Underwater earthquakes can cause huge waves called tsunamis, which hit coasts far away from where the shaking happened.
  3. Sometimes, a small underwater earthquake might not be felt at all, but it could still set off big waves in deep water.
