震级

A magnitude 8.7 earthquake is 794 times BIGGER on a seismogram than a magnitude 5.8 earthquake.

译：8.7级地震在地震记录仪上比5.8级大794倍，震级是用对数计算出来的，计算如下

Probably the best-known gauge of earthquake intensity is the local Richter magnitude scale, developed in 1935 by United States seismologist Charles F.

或许最著名的地震强度测量是区域里氏震级，是由美国地震学家查尔斯·里希特1935年确立的。

An earthquake with a magnitude of less than 2.0 is so slight that usually only a seismometer can detect it.

小于2.0震级的地震非常轻微，通常只有地震检波器才能探测到。

Geological Survey National Earthquake Information Center said the quake had a preliminary magnitude of 7.6 and was centered 145 kms (90 miles) south-southwest of Taipei.

美国地质勘探局国家地震信息中心说，这次地震进行了初步的震级为7.6，被毁坏145公里(90英里)西南偏南台北。

It is found that the off west coast of South Island of New Zealand earthquake has several basic characteristics as follows:① Moment magnitude is about M 7.8; Rupture duration time is about 40 s;② The static slip distribution is simple and the whole rupture process contains only one slip concentrated patch; This earthquake is mainly a unilateral rupture event with the rupture propaga ting southwestward.

结果表明。这次新西兰南岛西海岸近海地震的破裂过程具有如下基本特征：①矩震级约为M7.8；②地震主要破裂持续时间约为40 s；③滑动量在断层面上的分布比较简单，整个地震破裂只包含一个滑动量较大的区域；④这次地震基本上是一次单侧破裂事件，破裂主要朝向西南方向。

The results also show that the module of state vector is more sensitive than other parameters stat...

研究结果还表明，相对于态矢量增量的模、态矢量方向的改变等参量，态矢量的模在震前的变化更为敏感，此外，对于相同震级的地震，最佳扫描区域尺度大小不一，并对这些现象进行了一定的解释。

The USGS has already measured more than 40 aftershocks above a 4.0 magnitude (including a 5.9 and 5.5 magnitude) and many more below that, Bedwell said.

贝德威尔说。美国地质勘探局已经估计将有4.0级以上（包括5.9级和5.5级）余震40多次，还有许多震级更低的余震。

Degrees epicentral intensity, and the scope of damage radius of 380 kilometers.

这是北京附近地区历史上最大的一次地震，震级估计为8级。

It reported the large number of earthquakes, with "the largest being M 4.7," and slight damage in what was to become the epicentral area.

它报告已发生了许多地震，&其中最大的震级为M4.7&，在后来成为震中的地区造成了轻微的破坏。

For earthquakes between M6.5-7.0 and the largest potential earthquake in the region,we should account for other two models including geodetical model and fault model.From physical aspect,we can constrain seismicity parameters by utilizing GPS data and fault slip rate.

对于震级6.5或7.0级以上的地震危险性分析，可以考虑另外两种模型，即大地测量和断层模型，从物理的角度，利用GPS数据和断层滑动速率来约束地震活动性参数。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
