2017年8月9日精河MS6.6地震余震序列精定位及发震构造分析

Dizhen xuebao, 2019
为确定2017年8月9日精河MS6.6地震的发震构造，本文使用双差定位方法对发震时刻至2017年10月震源区所发生的余震进行了精定位，同时利用CAP波形反演方法，得到了主震的震源机制解，同时使用GPAT方法反演得到了部分余震的震源机制解，并基于两者对本次地震的发震构造予以分析。结果显示：精定位后主震位于（44.27°N，82.85°E），震源深度为17 km；主震最佳双力偶解对应的节面Ⅰ的走向为260°、倾角为51°、滑动角为84°，节面Ⅱ的走向为89.5°、倾角为39.4°、滑动角为97.4 ...
