Earth Science for Kids: Tsunamis - Ducksters.
How Tsunamis are Formed Do you know how Tsunamis are formed? This worksheet diagrams the physics behind tsunami formation, which starts with an earthquake or volcanic eruption under the ocean.
This essay will address the factors that affect the quality of human life in the 2011 Japan and 2004 South Asia tsunamis, and what made them become two of the word’s biggest disasters. Tsunamis become disasters when they result in loss of lives, injuries, and displacement of human population.
Tsunami - What is it? A tsunami is a huge volume of moving seawater. These giant waves can travel for thousands of miles across the sea and still have enough energy and force to destroy buildings, trees, wildlife and people. If you throw a stone in a pond it will create a series of ripples.
A volcano is an opening in Earth ’s crust. When a volcano erupts, hot gases and melted rock from deep within Earth find their way up to the surface. This material may flow slowly out of a fissure, or crack, in the ground, or it may explode suddenly into the air. Volcanic eruptions may be very destructive. But they also create new landforms.
A 2011 earthquake off the coast of northern Japan, for example, sparked a tsunami that reached as high as 40.5 meters (133 feet). It destroyed entire towns. And a 2004 earthquake in Indonesia sent tsunami waves throughout the Pacific, Indian and Atlantic Oceans. That tsunami killed some 230,000 people in 14 countries. There’s no stopping a.
Tsunami waves are not like the usual waves that you catch for surfing. They can be hundreds of feet high in shallow water and as fast as 500 miles per hour! Some of these violent waves have enough force to flip cars around, wreck houses and buildings, and wipe out entire villages in a matter of a few minutes!
Unfortunately, the earthquake also caused a tsunami. A tsunami (pronounced “soo-nom-ee”) is a “giant sea wave caused by an earthquake or volcano.” As you know, Japan is an island. The earthquake happened just off the coast, in the water near the city of Sendai.
