| 摘 要： | 利用从IRIS上获取的11个台站震相清晰的P波波形记录资料对2000年姚安MS6.5地震的震源破裂过程进行了反演,结果表明:(1)地震破裂持续时间为5.6s,破裂主要集中在破裂开始0.2s后的时间段内,由两次2s多的破裂组成,而且后一次破裂的强度超过了前一次;(2)静态滑动位移和应力降分布图均显示存在震中区和震中以东区两个变化比较明显的区域,破裂沿北西向断裂进行。 |
| 关 键 词： | 震源破裂 反演 姚安地震 |

| Abstract: | Source rupture process of the clearly P waves of 11 stations adapted from IRIS about Yaoan M_S6.5 earth-quake taking place in 2000 is inversed. The results indicate: ①The rupture time is 5.6 seconds and the rupture mainly focuses on the first 0.2 second. The total rupture is consisted of two ruptures lasting for over two seconds separately, and the latter is more strong than the former. ②Two regions can be seen from the static slip distribu- tion map and the stress drop distribution map, and the rupture developed along the Northwest direction. |
