An earthquake (also known as a quake,tremor or temblor) is the result of a sudden release of energy in the Earth's crust that creates seismic waves.The seismicity or seismic activity of an area refers to the frequency,type and size of earthquakes experienced over a period of time.Earthquakes are measured using observations from seismometers.The moment magnitude is the most common scale on which earthquakes larger than approximately 5 are reported for the entire globe.The more numerous earthquakes smaller than magnitude 5 reported by national seismological observatories are measured mostly on the local magnitude scale,also referred to as the Richter scale.These two scales are numerically similar over their range of validity.

地震(也称为地震、震颤或警报)的结果是一个突然的释放能量在地壳创造了震波.地震或地震活动面积是指频率、类型及大小的地震经验丰富的经过一段时间的.利用地震观测到的地震检波器测量.这是最常见的矩震级的地震规模上大于大约5所报道的上述产品销往全球.有更多的次5级地震的报道小于由国家地震观测站测量大都是在当地的量级,也被称为里氏震级.这两个天平是在他们的各种数值相似的有效性.
