This research attacks one of the most difficult seismological problems - predicting strong high-frequency ground motion from complex faulting, and inverting observations for a source model. The analysis will use extensive seismic data sets from the California Whittier Narrows earthquake of October 1, 1987, and from earthquake areas in Taiwan. The research has direct and important application to the National Earthquake Hazards Reduction Program in predicting the particularly damaging local high-frequency ground motions during an earthquake.

这项研究解决了地震学中最困难的问题之一--从复杂的断层作用预测强烈的高频地面运动，并对震源模型进行反演观测。分析将使用1987年10月1日加州惠蒂尔纳罗斯地震和台湾地震区的广泛地震数据集。该研究对国家防震减灾规划中预测地震过程中特别具有破坏性的局部高频地震动具有直接而重要的应用。
