震级是地震释放能量的大小。震级小于3级的地震为弱震;震级大于或等于3级,小于或等于5级的地震为有感地震;震级大于5级小于6级的地震为中强震;等于或大于6级的地震为强震,
Magnitude is the amount of energy released by an earthquake. Earthquakes with magnitudes lower than 3 are weak earthquakes; earthquakes with magnitudes greater than or equal to 3 and less than or equal to 5 are sensible earthquakes; earthquakes with magnitudes greater than 5 and less than 6 are moderate earthquakes; earthquakes with magnitudes equal to or greater than 6 are Strong earthquake,
