Earthquake focal mechanism catalog for Mexico

We present a focal mechanism catalog for earthquakes that occurred in Mexico and surrounding areas reported from February 1928 to July 2022. The magnitude of the events varies from -0.9 to 8.2. The hypocentral depth is in the range of 0 < Z < 270 km. Reported fault plane solutions were derived using different types of data at local, regional, and teleseismic distances and different methods such as first motions, composite solutions, waveform analysis, and moment tensor inversion. Our catalog consists of 5701 fault plane solutions, and we report all the available focal mechanisms obtained by different authors and seismological agencies for each seismic event.

我们构建了一份收录1928年2月至2022年7月期间墨西哥及周边区域已报道地震的震源机制（focal mechanism）目录。本次收录地震的震级范围为-0.9至8.2，震源深度区间为0 < Z < 270千米。本目录所包含的断层面解（fault plane solutions），基于近场、区域及远震距的多类观测数据，通过初动法、综合解分析、波形分析以及矩张量反演（moment tensor inversion）等多种方法推导得到。本目录共计收录5701条断层面解，完整留存了不同研究者与地震机构针对各地震事件获取的全部可用震源机制数据。
