双震型地震

双震型地震b值低、k值为0.1，能量比介于99.0%&99.4%之间。

For the earthquake with the double earthquake type in Jiashi earthquake sequence , the value of b is low , the value of k is 0.1 , and the energy rate of them is in ( 99.0 ) % & ( 99.4 ) % .

研究表明在某些方面，8月15日中强震序列反映出其前震特征，而11月6日强震序列则明显反映出双震型地震的特征。

Whereas the strong earthquake sequence on Nov. 6 obviously presented features of twin shocks .

本文对一九七六年龙陵、松潘、盐源三组双震型强震，从地震地质、余震分布结合前人模拟实验的成果和震源机制解的分析，对它们的成因机制作了探讨。

In the light of seismogeology , the fault plane solutions , the distribution of aftershocks and the previous simulation experiments , this paper makes a brief discussion on the genetic mechanism of three groups of strong double earthquakes , i.

讨论了1965年以来云南地区强震孕育过程中地震类型的动态变化，发现：云南地区发生6.7级以上强震前数月至数年，云南省内均有2次以上5级双震或群震型地震发生；

The dynamic changes of earthquake types during strong earthquake preparation processes since 1965 in Yunnan were discussed . It was found that more than two M5.0 double earthquakes or swarm earthquakes occurred several months or years before M ≥ 6.0 strong earthquakes .
