Integrated study of source, path, and site effects on Kocaeli, Turkey, earthquake ground motions

1999年8月17日土耳其科贾埃利地震（M=7.4）的破坏性特别大，因为断层在一个人口稠密的城市地区破裂。 本项目是对控制地面运动性质的因素进行综合研究：震源、波沿沿着的传播以及记录地点这些运动的近地表变化。地面运动可能类似于美国走滑断层上这种震级地震的运动，特别是在旧金山弗朗西斯科湾地区和大洛杉矶地区。 这项研究的一个关键结果将是校准复合源模型的参数，用于与圣安德烈亚斯断层上的地震相当的走滑地震。

The Kocaeli, Turkey, earthquake (M=7.4) of 17 August 1999 was particularly destructive because the fault ruptured in a densely developed urban area. This project is for an integrated study of the factors that controlled the nature of the ground motions: the earthquake source, wave propagation along the path, and near-surface modifications of these motions at the recording sites.The ground motions may be analogous to motions from earthquakes of this magnitude on strike-slip faults in the United States; in particular for the San Francisco Bay area and the Greater Los Angeles region. One critical result of the study will be calibration of parameters of the composite source model for a strike-slip earthquake with slip comparable to an earthquake on the San Andreas fault.
