1·Earthquake magnitude: 7.7.

震级：7.7。

2·What are the earthquake magnitude classes?

地震震级如何划分？

3·Sometimes the earthquake magnitude is reported by different networks based on only their recordings.

有时，不同地震台网仅仅使用自己的记录来报道地震震级。

4·That being said, damage does not usually occur until the earthquake magnitude reaches somewhere above 4 or 5.

不过一般来说，4或5级的地震通常代表着明显的破坏和损失的开始。

5·And the conventional least-square method is extended to deal with fuzzy earthquake magnitude by the vertex method in the analysis.

在分析中应用顶角法把传统的最小二乘法加以延伸来处理模糊地震震级。

6·This paper presents a methodology for determining earthquake recurrence relationships using fuzzy information of earthquake magnitude.

本文采用地震震级的模糊信息提出确定地震重现关系的一种方法。

7·With the existing seismic monitoring network, it is not a problem that we confirm the earthquake magnitude and epicenter location in a short time.

借助于现有的地震监测台网，在短时间内获取地震的震级和和震中位置已不成问题。

8·According to the calculating principle of wind scale and earthquake magnitude, the concepts of magnitude and disaster degree of storm surge are put forward.

根据风级和震级的计算原理，提出了风暴潮等级和灾度的概念。

9·And the upper limit of reservoir earthquake magnitude is estimated according to the structural reservoir earthquake, the sections which earthquake occurred are also estimated.

从发生构造型水库地震角度，对水库地震的震级上限进行了估算。

10·According to the calculating principle of wind scale and earthquake magnitude, the concept of the magnitude of self-purification capacity of water environment of area was put forward.

根据地震等级和风力等级的计算原理，提出了区域水环境自净能力等级的概念。
