This research program considers the spatial variation and correlation of strong earthquake ground motion. It is common in earthquake engineering to focus on the time history of ground acceleration at a given location. However, the spatial variation of ground motion is potentially just as important as the time variation, and is the focus of this study. This research program includes analytical modeling of ground motions, and statistical analysis of closely spaced accelerograms, principally from strong motion instrument arrays, and especially the accelerograms recorded during the September 19, 1985 earthquake. It also involves a study of patterns of building damage and variations in local geology, all to obtain insight into the spatial variation of strong ground motion.

该研究计划考虑了空间变化和相关性 强烈的地震地面运动。 在地震中很常见 工程的重点是地面加速度的时间历史， 给定位置。 然而，地面运动的空间变化是 可能和时间变化一样重要， of this study研究. 该研究计划包括分析建模， 地震动，以及近距离地震的统计分析 主要来自强震仪器阵列的加速度记录，以及 特别是1985年9月19日 地震 它还包括对建筑物损坏模式的研究 以及当地地质的变化，所有这些都是为了深入了解 强地面运动的变化。
