Frequency Domain Inversion of Earthquake Ground Motion Along the Mexican-Subduction Zone

本提案的主要目标是利用墨西哥太平洋沿岸格雷罗阵列的强震记录，对近源和远源地震波形式进行反演，以确定近期中等规模地震期间滑动的时空行为。这个阵列在记录强震波方面非常有价值，包括1985年的8.1级地震。本工作将应用研究者开发的频域源反演方法。研究结果可直接应用于国家防震减灾工程。

The major objective of this proposal is an inversion of both near-source and teleseismic wave forms to determine the temporal and spatial behavior of slip during recent moderate-sized earthquakes utilizing strong-motion recordings of the Guerrero array on the Pacific coast of Mexico. This array has been extremely valuable in the recording of strong-motion waves from earthquakes including the 1985 magnitude 8.1 event. This work will apply the frequency domain source inversion method developed by the investigators. The research has direct application to the National Earthquake Hazard Reduction Program.
