TWO weeks ago Ruichang City in Jiangxi Province was hit by an earthquake measuring 5.7 on the Richter scale. It killed 18 people and left hundreds homeless.

　　兩周前，江西省瑞昌市遭遇了一場(chǎng)里氏5點(diǎn)7級(jí)的地震，有18人喪生，數(shù)百人無(wú)家可歸。

　Earthquakes are one of the most deadly natural disasters in the world. They happen more frequently than you would expect.

　　地震是地球上最具毀滅性的自然災(zāi)害之一。它的發(fā)生比你想象的要更頻繁。

　In the 24 hours after you read this, 400 to 500 earthquakes will shake the earth. You won't notice most of them because you live in a relatively stable area or the quake is too far away or because the quake will be too small to notice.

　　就在你讀到本文之后的24小時(shí)之內(nèi)，地球上就會(huì)發(fā)生400到500次地震。大多數(shù)地震你不會(huì)注意到，原因在于，你居住的地區(qū)相對(duì)來(lái)說(shuō)比較平穩(wěn)，或者你距地震很遠(yuǎn)，或者地震太小而注意不到。

　Earthquakes are caused by sudden breaks in rock masses deep in the earth. Rock masses are always under very high pressure. If the pressure in a certain area become too much and the rock masses break, an earthquake happens. But exactly when the rock masses reach the breaking point is a mystery.

　　地震是由于地球深層的巖層突然斷裂而引發(fā)的。巖層長(zhǎng)期處于地應(yīng)力的作用下。如果某處的地應(yīng)力太強(qiáng)使巖層斷裂，就會(huì)發(fā)生地震。但是，巖層承受的最強(qiáng)地應(yīng)力究竟是多少，卻仍然未知。

　China is located on the Eurasia plate, where earthquakes happen frequently due to the earth's plates knocking against each other. Up to 17,139 earthquakes have taken place in China in the past 44 years, according to scientific research.

　　中國(guó)處于亞歐板塊，這是板塊之間互相撞擊的區(qū)域，因此地震活動(dòng)頻繁?？茖W(xué)調(diào)查顯示，在過(guò)去的44年中，中國(guó)一共發(fā)生了17139多起地震。
