Tsunamis occur most often in the Pacific Ocean and Indonesia because the Pacific Rim bordering the Ocean has a large number of active submarine earthquake zones. 2  However, tsunamis have also occurred recently in the Mediterranean Sea region and are expected in the Caribbean Sea as well.
Tsunamis can also occur because of landslides. When land subsides into water bodies (usually extremely large landslides), they can create a wave that resembles a tsunami. The wave of these kinds of tsunamis will not be very high, unless a huge volume of rock or ice is involved. Tsunamis can also occur when asteroids fall into the water bodies.
