| 摘 要： | 应用应力触发理论原理,基于断层相互作用理论,研究了川滇地区6级以上地震的库仑破裂应力变化。初步结果表明,后续强震大多发生在前一地震所触发的应力增长区,这证明了强震之间是相互作用、相互影响的。即强震是成组孕育、成组发生的,这对强震的地点预测有一定实际意义。

Preliminary study on strong earthquake occurred in groups based on the theory of fault interaction |
| |
| Abstract: | According to the principle of earthquake stress triggering theory, based on the principle of fault interaction, the authors studied Coulomb failure stress chang e of earthquakes with magnitude above 6 in the Southeast China area. The prelimi nary result indicates that subsequent strong earthquakes mostly occurred in the tress increasing area caused by the previous earthquakes. It proves the strong e arthquakes are interactive, that is to say, strong earthquakes are prepared and occurred in groups. It might be of practical significance in the prediction of e arthquake risk areas. |
