1 . Some countries have a large number of earthquakes. Japan is one of them, while others do not have many, for example, there are few earthquakes in Britain.
There is often a great noise during an earthquake.
The ground vibrates (颤动).Houses fall down. Railways are broken, which causes trains to turn over. Sometimes thousands of people are killed in different ways. About 60,000 were killed in 1783 in the south of Italy. Some people say that earthquakes often happen near volcanoes(火山), but it is not true. The centres of some earthquakes are under the sea. The bottom of the sea suddenly moves. The powerful forces inside the earth break the rocks. The coast is shaken and great waves appear. These waves travel long distances and rush over the land when they reach it, breaking down houses and other buildings. Sometimes they break more buildings than the earthquake itself.
A terrible earthquake happened in Assam, India, in 1986.The land near Shillong suddenly moved 1.5 feet to one side, and then back again. It continued to act like this 20 times a minute.Few buildings could stand what was happening and the great stones flew four feet up into the air. What kind of building stays up best in an earthquake? The Americans carefully studied the results of the earthquake at San Francisco(1906) and believed it best for buildings to be made with concrete(混凝土) walls together by steel frames. Such are the buildings that can't burn or fall easily.
