地震是一种自然现象。据统计,全世界每年大约发生500多万次地震,绝大多数地震由于发生在地球深处,或者它所释放的能量小而难以被感觉到。人们能感觉到的地震叫有感地震,占地震总数的1%左右。造成灾害的强烈地震则更少,平均每年发生十几次。强烈地震会引起地面剧烈摇晃和颠簸,并会危及人民的生命财产安全和造成工程建筑物的破坏。另外,地震还可能带来火灾、水灾、山崩、滑坡以及海啸等各种灾难。 Earthquakes are a natural phenomenon. According to statistics, there are more than five million earthquakes in the world each year. The vast majority of earthquakes are difficult to be felt because they occur deep in the earth or because the energy it releases is small. Earthquakes that people can feel are called earthquakes, which account for about 1% of the total number of earthquakes. Strong earthquakes that cause disasters are even less, with an average of more than a dozen times a year. A strong earthquake can cause severe shaking and bumping of the ground and endanger people’s lives and property and cause damage to engineering buildings. In addition, earthquakes can also cause disasters such as fires, floods, landslides, landslides, and tsunami.
