Read the text about tsunami. Tsunamis are a series of waves in the ocean that create surges of water. These walls of
water can reach up to 100 feet high and cause widespread destruction when they reach shore.
Earthquakes on the sea floor are the usual cause of tsunamis. When the ocean floor at a plate
boundary rises or falls, it displaces water and sends rolling waves that become a tsunami. Around
80 percent of tsunamis happen in the so-called "Ring of Fire" in the Pacific Ocean. This is a
volcanically active area were tectonic plate shifts and earthquakes are common. Underwater
landslides and volcanic eruptions can also start tsunamis. In Earth's ancient past, tsunamis were
caused by a meteorite crashing into the ocean. People's best defense against tsunamis is early
warnings that allow people to evacuate areas near the ocean.
