This research program will investigate the source, progapation path, and basin effects that produced the strong ground motion observed during the Mexican Earthquake of September 19, 1985. This earthquake occurred in the Michoacan "seismic gap," and a high probability exists that a large earthquake will occur in the nearby Guerrero seismic gap within the next decade. Such an event could be as damaging to Mexico City as was the September 19,1985 earthquake. This research program will seek to obtain practically useful estimates of the strong ground motion shaking that would result from this event. Given the high probability of occurrence, there is therefore a good chance that these estimates can be checked against measured data in the near future. Such an estimate, and comparison with measured data, is expected to result in signficant advances in the techniques for estimating seismically generated strong ground motion.

该研究计划将调查 1985 年 9 月 19 日墨西哥地震期间观察到的强烈地面运动的来源、传播路径和盆地效应。这次地震发生在米却肯州的“地震间隙”，并且很可能存在大范围的地震。未来十年内，附近的格雷罗地震间隙将发生地震。 此类事件对墨西哥城的破坏可能与 1985 年 9 月 19 日的地震一样。 该研究计划将寻求获得对该事件可能导致的强烈地面震动的实际有用的估计。 鉴于发生的可能性很高，因此很有可能在不久的将来可以根据测量数据来检查这些估计值。 这种估计以及与测量数据的比较预计将导致估计地震产生的强地面运动的技术取得重大进步。
