1.How high can a tsunami be?
:In some places a tsunami may cause the sea to rise vertically only a few inches or feet. In other places tsunamis have been known to surge vertically as high as 100 feet (30 meters). Most tsunamis cause the sea to rise no more than 10 feet (3 meters).
2.What most often causes tsunamis?
:Most tsunami are caused by large earthquakes on the sea floor when slabs of rock move past each other suddenly, causing the overlying water to move. The resulting waves move away from the source of the earthquake event.
3.Where do most tsunamis occur?
:Most tsunamis–about 80 percent–happen within the Pacific Ocean's “Ring of Fire,” a geologically active area where tectonic shifts make volcanoes and earthquakes common.
4.What are two other ways tsunamis can be caused?
:Landslides. A landslide that occurs along the coast can force large amounts of water into the sea, disturbing the water and generate a tsunami. Volcanic Eruption.
5. What is the best defense against tsunamis?
The best protection is nature itself. This was the lesson to be learned from the Indian Ocean tsunami. Coral reefs provide a good defence. They weaken the tsunami on their way ashore.

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.
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 raises or falls, it displaces water and sends rolling waves that become a tsunami. Around 80 percent of tsunamis happen in the so-called
