Five things you should know about earthquakes.

關(guān)于地震你應(yīng)該知道的5點(diǎn)

Number one, an earthquake occurs when two blocks of the Earth slip fast each other. Now, for most of the time, those blocks are together with friction. But they are building up energy because they are moving in different directions. When one block decides to slip, all of a sudden, that energy is released by seismic waves, kind of like ripples on a pond, creating the earthquake.

第一，地球上兩個板塊相互滑動就會產(chǎn)生地震?，F(xiàn)在，多數(shù)時間，這些板塊在相互摩擦。但是，因為在向不同的方向移動，所以會積聚能量。當(dāng)一個板塊下沉，千鈞一發(fā)，這些能量就會以地震波的形式釋放，就像池塘中的漣漪，然后引發(fā)地震。

Number two, an earthquake can occur very near the surface of the Earth. Those earthquakes are typically very destructive, or as deep as 400 miles down into the crust. Now, where the shaking actually happens, that`s called the hypocenter. But directly above it, on the surface, that`s called the epicenter.

第二，地震可能發(fā)生在距離地表很近的位置。但一般而言，這種類型的地震非常具有破壞性，波及距離可深達(dá)400英里深?，F(xiàn)在，地震發(fā)生的位置，被稱為震源。但是其垂直向上的地表位置，被稱為震中。

Number three, the power of an earthquake is called magnitude. Now, the intensity of he shaking can vary depending on the geography, the typography, or even the depth of the quake. Now, the USGS says there are 500,000 detectable quakes every year. One hundred thousand can be felt and 100 will create damage.

第三，地震的能量級別被稱為震級?，F(xiàn)在，震動強(qiáng)度可能因地理位置、地形、甚至深度而有所不同?，F(xiàn)在，美國地質(zhì)調(diào)查局表示，每年可檢測到50萬起地震。其中人們可感受到10萬起地震，而有100起地震會造成傷害。

Number four, earthquakes themselves actually don`t kill that many people. It`s the natural and manmade structures that fall to the ground during the shaking that injure and kill.

第四，地震本身并沒有造成人員傷亡。是由于在地震時的自然結(jié)構(gòu)和人工建筑導(dǎo)致傷亡。

Number five, the majority of all earthquakes and volcanoes happen along plate boundaries. The largest is the Pacific plate and its series of boundaries all along the Pacific Ocean known as the Ring of Fire.

第五，大部分的地震和火山都是沿著板塊邊界發(fā)生。最大的是太平洋板塊及其沿太平洋的一邊界，被稱為“火環(huán)”。
