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 Mw 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 Mo(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.
期刊介绍：
Doklady Earth Sciences is a journal that publishes new research in Earth science of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
