The March 28, 1787 (M∼8.6) earthquake on the Pacific coast, was the biggest known in Mexico. There are testimonies of damage caused by the tsunami waves at several different points along the southwest coast. Even though there have been several tsunamis known to have impacted this region, there are scarce tsunami observations. In this study, we generate a suite of 350 potential ruptures that we explore as candidates for the 1787 San Sixto earthquake. We focus this study in three coastal areas: Salina Cruz, Huatulco and the Mazunte-Puerto Ángel segment of the Oaxacan coast. We will discuss results of the homogeneous and heterogeneous slip models as input for tsunami simulations. The results obtained for every particular town and possible tsunami effects such as resonance, wave energy focusing and prone inundation areas are discussed. The scope of this work is to greatly expand on previous tsunami modeling efforts as an important tool for studies of tsunami hazards for future events in order to increase resilience in coastal populations.

1787 年 3 月 28 日（M∼8.6）太平洋沿岸的地震是墨西哥已知的最大地震。在西南海岸的几个不同地点都有海啸造成破坏的证词。尽管已知有几次海啸影响了该地区，但海啸观测资料却很少。在这项研究中，我们生成了一组 350 个潜在破裂，我们将这些破裂作为 1787 年圣西斯托地震的候选者进行探索。我们将这项研究集中在三个沿海地区：Salina Cruz、Huatulco 和 Oaxacan 海岸的 Mazunte-Puerto Ángel 段。我们将讨论均质和异质滑移模型的结果作为海啸模拟的输入。讨论了针对每个特定城镇获得的结果以及可能的海啸效应，例如共振、波能聚焦和易受淹没区域。这项工作的范围是大大扩展以前的海啸建模工作，作为研究未来事件的海啸危害的重要工具，以提高沿海人口的复原力。
