Question

Why do the majority of tsunamis occur in the Pacific Ocean?

Answer 1

That's where the tectonic plates move the most and create more crust

Answer 2

Tsunamis happen most frequently in the Pacific Ocean because of the many large earthquakes associated with subduction zones along the margins of the Pacific Ocean basin, which is called the "Ring of Fire". Ninety percent of the world's earthquakes occur along the Ring of Fire.
