An earthquake is caused by a sudden slip on a fault (断层). A fault is a fracture in the crust (地壳) of the earth along which rocks on one side have moved relative to those on the other side. Stresses in the earth’s outer layer push the sides of the fault together, build up, and then the rocks slips suddenly, releasing energy in waves that travel through the rock to cause the shaking that we feel during an earthquake.
Earthquakes tend to be concentrated in narrow zones. There are 7 major crystal plates on earth, about 80 km thick, all in constant motion relative to one another. They move at a rate of between 10 and 130 mm per year.
It is estimated that there are several million earthquakes in the world each year. Many of these earthquakes go undetected because they occur in remote areas or have very small magnitudes (震级). The USGS Earthquake Information Centre locates 12, 000 to 14,000 earthquakes each year (about 35 per day). On average, about 60 earthquakes p

[单项选择]Earthquake is a shaking of the ground caused by the sudden breaking and the shifting of large sections of the earth’s rocky outer shell. Earthquakes are among the most powerful events on earth, and their results can be terrifying. A severe earthquake may re-lease energy 10,000 times as great as that of the first atomic bomb. Rock movements dur-ing an earthquake can make rivers change their courses. Earthquakes can trigger landslides that cause great damage and loss of life. Large earthquakes beneath the ocean can create a series of huge, destructive waves called tsunamis that flood coasts for many miles.
Earthquakes almost never kill people directly. Instead, many deaths and injuries in earthquakes result from falling objects and the collapse of buildings, bridges, and other structures. Fire resulting from broken gas or power lines is another major danger during a quake. Spills of hazardous chemicals are also a concern during an earthquake.
