摘要
从震例总结的角度,介绍了2015年10月12日玛多5.2级地震发震构造背景、余震序列和利用数字地震波资料计算研究主震震源机制及余震序列视应力。结果表明,本次地震序列为孤立型地震,属左旋走滑类型,视应力值明显偏低。该结果有利于全面了解和认识玛多地震,也为今后的对比研究提供参考依据。
The seismogenic tectonic background and aftershock sequence of Maduo M 5.2 earthquake on Octo- ber 12,2015 are introduced in the paper, and main focal mechanism and the aftershock sequence apparent stress arc studied by the digital seismic data. Results show that the earthquake sequence is signal event, and its fault is sinistral strike-slip type, and the apparent stress value is lower. The result is helpful to fully research Maduo M 5.2 earthquake and also provide a reference basis for the comparison research in the future.
