When two of the pieces move against each other or move in opposite directions, an earthquake happens. A large movement causes a violent earthquake, and a small movement causes a mild one. There are thousands of earthquakes every year, but most of them are very small.
The place where an earthquake begins is called the epicenter. When an earthquake happens, vibrations move outward from the epicenter. These rolling vibrations are called seismic waves. Usually, an earthquake is only strong enough to cause damage near its epicenter.
When the epicenter of an earthquake is at the bottom of the ocean, it can create huge sea waves as tall as fifteen meters. These waves cross the ocean in several hours. Rushing toward land, they destroy small islands and ships in their path. When they hit land, they flood coastal areas far from the epicenter of the earthquake. When a huge tsunami happened in the Indian Ocean in 2004,the wave reach two kilometer inland, killing 230000 people in eleven countries
After an earthquake happens, people can die from lack of food, water, and medical supplies. The amount of destruction caused by an earthquake depends on where it happens, what time it happens, and how strong it is. It also depends on the types of buildings in the area, the soil conditions, and the size of the population. Of the thousands of earthquakes in the world each year, only about one in 500 causes damage.
In 1556,an earthquake in northern China killed 830,000 people-the most in history. At that time, there was no way to measure its strength. In 1935, scientists started using the Richter Scale to measure seismic waves. A seriously destructive earthquake measures 6.5 or higher on the Richter scale (this has now been largely replaced by the Moment Magnitude scale which uses the same scale system, but is more accurate).
