摘要

摘要介绍了 2016 年 11 月 25 日在中国木垒附近发生的 Mw 6.6 级阿克陶强烈地壳地震震中区的应力应变状态建模结果。本文采用有限元法对震中区的应力应变状态进行建模，并随后绘制了地震前后的应力强度图。图中显示了确定断裂起源位置及其范围的可能性，包括标量地震力矩和震级的估算。根据破裂（地震焦点）的应力-应变状态模型，首次提出了计算地震力矩率作为时间 Mo(t) 函数的可能性，从而可以获得未来潜在地震的合成地震图和加速度图。

Seismotectonic Model of the Focal Zone of the November 25, 2016, Aketao Earthquake MW 6.6 (China)

Abstract

The results of modeling the stress–strain state of the epicentral zone of the strong crustal earthquake Aketao, which occurred near Muji (China) on November 25, 2016, with magnitude M_w 6.6, are presented. The finite element method is used to model the stress–strain state in the epicentral zone with subsequent construction of stress intensity maps before and after the earthquake. The possibility to determine the location of the rupture origin and its extent, including estimation of the scalar seismic moment and the earthquake magnitude, is shown. The possibility to calculate the seismic moment rate as a function of time M_o(t) based on the model of the stress–strain state of rupture (earthquake focus) is presented for the first time, which allows obtaining synthetic seismograms and accelerograms of a potential earthquake in the future.
