Over one million earthquakes happen every year. But most of them are too small to notice. An earthquake can happen on land or under water. A major quake may last for only a minute, but it can kill thousands of people. It also may destroy a whole town or village. On 1 September, 1923, a huge quake hit two Japanese cities. Only about 1% of buildings were damaged. But great fires broke out in this disaster. The fire burned the wood and paper houses.
