- The moment magnitude scale measures the total energy released in an earthquake and it describes large earthquakes more accurately than does the Richter scale. 力矩量级可以测量地震释放的总能量,并且用它来描述大地震比用里氏震级要精确得多。
- Although large earthquakes are customarily re ported on the Richter scale, scientists prefer to de scribe earthquakes greater than 7.0 on the moment magnitude scale. 尽管大地震常以里氏震级来报道,但科学家喜欢用力矩量级来描述大于7.;0级的地震。
- Although large earthquakes are customarily reported on the Richter scale,scientists prefer to describe earthquakes greater than 7.0 on the moment magnitude scale. 尽管大地震常以里氏震级来报道,但科学家喜欢用力矩量级来描述大于7.;0级的地震。
- There are about 10 times as many quakes for every decrease in Richter magnitude by one unit. 里氏震级每降低一个单位,地震发生的数量就会增加10倍。
- The Richter scale measures the largest wiggle on the recording, but other magnitude scales measure different parts of the earthquake. 通过这个方式,那些(由于岩石层摩擦产生的)能量在地震中以冲击波的形式得以释放。
