地震波是通过地表传播的波体，通常是由地壳震动或爆炸引起的。
Seismic waves are waves that travel through the Earth, most often as the result of a tectonic earthquake, sometimes from an explosion.
地震通常由断层的突然滑动所致，除了地壳震动外，更因释放能量引发其他灾难，例如火灾、滑坡及海啸。
Earthquake is usually caused by a sudden slip on a fault, resulting in ground shaking and release of seismic energy. Fire, landslide and tsunami are common hazards following an earthquake.
地震是一种穿过地壳的震动。
An earthquake is a vibration that travels through the earth's crust.
英国的地震都是由建筑物震动，是由地壳绷紧时最终移动引起的。
Earthquakes in the UK are all tectonic quakes, triggered when the Earth's crust is subjected to strain and eventually moves.
那些震动的强大力量到将会朝太空发出伽马射线释，让科学家们怀疑这些星球的地壳一定很难打破。
The awesome power of those quakes can blast gamma rays into space, leading scientists to suspect that the stars' crusts must be very hard to break.
当在边缘上的压力超过摩擦力时，能量通过地震以波的形式释放出来，穿过地壳造成我们所感觉到的震动。
When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.
震动图是地震仪的测量结果的纸质记录，是用来确定地震发生的地区和震级。它们记录了在过去一段时间里地壳的运动情况。
Seismograms are the records (paper copy) produced by seismographs used to calculate the location and magnitude of an earthquake. They show how the ground moves with the passage of time.
