This article presents stratigraphic data and radiocarbon dates combined with Bayesian modeling from San Andrés in the Zapotitán Valley, El Salvador, focusing on the Campana Structure, the largest and longest-used monumental structure at the site. These data refine the regional chronology of the valley and provide insights into the emergence, development, and abandonment of this pivotal center in southeastern Mesoamerica and its potential links to three related volcanic eruptions: Ilopango, Loma Caldera, and El Boquerón. These distinct volcanic events had pronounced effects on local people who innovated new monumental construction projects and used new volcanic debris as construction material after major eruptions. It is suggested that these monumental public building projects played an important role in the post-disaster recovery of societies by helping foster a sense of corporate identity. The use of volcanic material in constructions at San Andrés and the building of these massive structures may also have helped keep these events alive in the communal memory.

本文介绍了地层数据和放射性碳日期以及来自萨尔瓦多萨波蒂坦谷的圣安德烈斯的贝叶斯模型，重点关注坎帕纳结构，这是该地点最大和使用时间最长的纪念性结构。这些数据完善了山谷的区域年表，并提供了对中美洲东南部这个关键中心的出现、发展和废弃及其与三个相关火山爆发的潜在联系的见解：Ilopango、Loma Caldera 和 El Boquerón。这些独特的火山事件对当地人产生了显着影响，他们在重大喷发后创新了新的纪念性建筑项目并使用新的火山碎片作为建筑材料。建议这些具有纪念意义的公共建筑项目通过帮助培养企业认同感，在社会的灾后恢复中发挥了重要作用。在圣安德烈斯的建筑中使用火山材料以及建造这些巨大的结构也可能有助于使这些事件在公共记忆中保持鲜活。
