El Infiernillo and La Villita earth dams in Mexico have been subjected to a number of earthquakes since their construction, but especially the Mexican earthquake of September 19, 1985. Measurements of strong-motion acceleration, crest displacements, and settlements were obtained during several of these earthquakes. This research program will utilize this information to verify numerical analysis techniques developed as a result of studies in the earthquake response of dams in the United States. In particular, the effects of successive earthquakes in changing the stress conitions, motion response, and performance of the foundation materials, will be examined.

墨西哥的 El Infiernillo 和 La Villita 土坝自建成以来遭受了多次地震，特别是 1985 年 9 月 19 日的墨西哥地震。在其中几次地震中获得了强震动加速度、坝顶位移和沉降的测量结果地震。 该研究计划将利用这些信息来验证美国大坝地震反应研究结果所开发的数值分析技术。 特别是，将研究连续地震对改变地基材料的应力条件、运动响应和性能的影响。
