Learning from the Mexican Earthquake of September 19, 1985: Estimation of Strong Ground Motions

这项研究计划将调查的来源，迁移路径， 以及盆地效应，产生了观测到的强烈地面运动 1985年9月19日墨西哥地震。 这次地震 发生在米霍坎“地震空区”， 附近的格雷罗地震间隙将发生大地震 在未来十年内。 这样的事件对墨西哥的破坏可能与 就像1985年9月19日的地震一样。 这个研究项目 将寻求获得实际有用的估计， 这一事件可能导致的震动。 考虑到高 发生的概率，因此，有一个很好的机会， 在不久的将来，可以根据测量数据对估计数进行核对。 这种估计以及与测量数据的比较预计将 导致技术的重大进步， 地震产生的强烈地面运动。

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.
