Why do earthquakes happen? Scientists believe that the surface of the earth is covered by a number of moving plates. Sometimes two plates move towards and push against each other. Sometimes they stop for years but at other times they jump and an earthquake is felt. Because of the movements of these plates, California, China and Japan have a lot of earthquakes. You can see the result in San Francisco where the Pacific plate meets the North American plate. When the 1906 earthquake happened, the Pacific plate jumped 5 to 6 metres to the north.
China is a country where many earthquakes happen. The Pacific plate is pushing China from the east and the Indian plate is pushing China from the southwest. The power of this movement created the Himalayas and Mount Qomolongma. It now causes earthquakes in China. We cannot stop earthquakes but we can do things to make sure they do not destroy whole cities. First it is not a good idea to build houses along the line where two plates meet. Second, if you think there may be an earthquake, make sure to build houses on rock rather than sand. Third, you must make the houses as strong as possible. Weak buildings will fall down in an earthquake, but strong ones may stay up.
