9416214 Archuleta This research involves the inversion of strong motion accelerograms using empirical Green's functions to determine the source mechanism of the Northridge earthquake. The data to be used include specially installed digital instruments at existing accelerometer sites. Although empirical Green's functions have been used in earlier studies, they have been limited by a lack of station distribution. The data here represent the best combination ever of station distribution and large aftershocks recorded from the hypocentral region of a large main shock. This project is a contribution to the National Earthquake Hazard Reduction Program and is supported by the Northridge Earthquake Emergency Appropriation. ***

9416214阿克莱塔这项研究涉及利用经验格林函数对强震加速度图进行反演，以确定北岭地震的震源机制。将使用的数据包括在现有加速度计站点专门安装的数字仪器。虽然在早期的研究中已经使用了经验格林函数，但由于缺乏站点分布，它们一直受到限制。这里的数据代表了台站分布和从大主震的震中区记录到的大余震的最佳组合。该项目是对国家减少地震灾害计划的贡献，并得到了北岭地震紧急拨款的支持。***
