China is one of the most earthquake-prone countries in the world and has suffered many disasters. During the last twenty years, especially since the Tangshan earthquake of July 1976 which killed 242,000 people and disabled almost 200,000 people, the Chinese government and the whole society have paid more attention to and made a huge effort to deal with earthquakes. Earthquake engineering became an essential project in the whole country and much more progress has been made since then. In this paper, some brief information about Chinese earthquakes and earthquake engineering is given. It is a simple introduction only, to give a general understanding of China's earthquake problems.

The effects of earthquakes are well known. Less known are their causes, hidden in the shifting pressures of the substrata of the earth. Their an nual number has been estimated at from 50,000 to 1,000,000; accurate instru mental locations date from about 1918. At present, seismographic stations register 600 to 700 a year, over a hundred of which are of major intensity. They cluster in two zones, one bordering on the Pacific Ocean and representing 80 per cent of the total energy released, the other running from Burma through the Himalayas westward through Europe's Alps. However, earthquakes may occur anywhere. They seem to run in cycles, but accurate prediction is impos sible. Planning can do much to reduce damage, but their relative rarity and unpredictability make planning difficult; it encounters barriers in inertia, self- interest, and long-term costs.—Ed.
"Earthquakes can be a slight shake almost no one notices. Or, they can be catastrophic events that level city blocks. In this book, readers learn how and why earthquakes happen as well as how scientists predict and measure them today. Some of the worst earthquakes in history-and their destruction-are discussed, as are safety tips readers can easily remember should they find themselves in an earthquake. Full-color photographs highlight the reality of a terrible earthquake accompanying achievable text full of earth science content"--
