We present the first parametric catalog of historical earthquakes in Mexico from 1469 to 1912 composed of 323 historical earthquakes. The historical earthquakes were assigned to specific seismotectonic provinces, and attenuation relations of seismic intensity versus distance were calculated using instrumental earthquakes. The intensity data were inverted using a linear regression for the best‐fitting magnitude and source location. From the 323 events identified in the historical record, magnitude and source location were determined for 40 earthquakes from 1568 to 1912. The historical subduction earthquakes are distributed uniformly along the coast. There is, however, a conspicuous absence of subduction earthquakes where the great 1985 Michoacán earthquakes took place. The data also show a large number of earthquakes Mw>7 in the presumed Guerrero gap in the past 320 yr. The source parameters of in‐slab earthquakes were obtained for 10 earthquakes that took place in the nineteenth and early twentieth centuries. The analysis of completeness of the historical and instrumental International Seismological Centre‐Global Earthquake Model catalogs of subduction earthquakes Mw>7.0 show similar values of the slope of the Gutenberg–Richter relation between 1.62 and 1.95. The large b‐values appear to reflect the apparently anomalous large number of earthquakes in the magnitude range Mw 7.4–7.7 and an absence of events Mw∼7⁠. This magnitude distribution suggests that the seismicity in the Mexican subduction zone is dominated by characteristic earthquakes in the magnitude range Mw 7.4–7.7, with larger earthquakes Mw>8 showing longer recurrence times. The catalog of historical subduction earthquakes appears to be complete for Mw>7.5⁠. The catalog of crustal earthquakes in the Trans‐Mexican volcanic belt is complete since 1568 for events Mw>6.4⁠. Completeness of the catalog of in‐slab earthquakes was not estimated due to the short record for this type of event.

墨西哥中部仪器前地震目录：基于大地震数据的震中和震级估计

我们介绍了1469年至1912年墨西哥的第一个历史地震参数化目录，其中包含323个历史地震。将历史地震分配到特定的地震构造省份，并使用仪器地震来计算地震强度与距离的衰减关系。使用线性回归对强度数据进行反演，以获得最合适的幅度和源位置。根据历史记录中确定的323个事件，确定了1568年至1912年的40次地震的震级和震源位置。历史俯冲地震沿海岸均匀分布。但是，在1985年的米却肯大地震中没有明显的俯冲地震。数据还显示大量地震Mw> 在过去的320年中，假设的格雷罗差距为7。板内地震的震源参数是针对19世纪和20世纪初发生的10次地震获得的。对历史地震和仪器地震国际地震中心-全球地震Mw> 7.0地震模型目录的完整性分析表明，古腾堡-里希特关系的斜率值在1.62和1.95之间相似。较大的b值似乎反映了在Mw 7.4-7.7范围内明显异常的大量地震，并且没有Mw〜7⁠的事件。这种震级分布表明，墨西哥俯冲带的地震活动主要发生在Mw 7.4-7.7范围内的特征性地震中，较大的Mw> 8地震表现出更长的复发时间。Mw>7.5⁠的历史俯冲地震目录似乎是完整的。自1568年以来，对于Mw>6.4⁠事件，跨墨西哥火山带的地壳地震目录已完成。由于此类事件的记录很短，因此无法估算板内地震目录的完整性。
