Tsunami
A tsunami is a series of ocean waves that send surges of water, sometimes reaching heights of 30.5meters onto land. These walls of water can cause destruction when they crash ashore.
These awe-inspiring waves are typically caused by large undersea earthquakes al tectonic plate boundaries.
The most tsunamis, about eighty percent happen within the pacific ocean ring of fire. A geologically active area where volcanoes and earthquakes are common.
The best defense against any tsunami is early warning that allows people to seek high ground.
