119628474 Humphreys This research involves the completion of analysis of results from the Snake River Plain, Idaho, project. This project involved the emplacement and recording of seismic data from 28 PASSCAL portable seismic systems over a 10 month period in 1993-1994 to delineate the upper mantle and crust of the Snake River Plain, a volcanic feature that is the result of the passage of the Yellowstone Hot Spot across the northwestern U.S. The need for additional funds is in part a result of the success of the experiment and the acquisition of much more usable data than was anticipated because of a high success rate for data recording and a high number of usable seismic events during the recording interval. The results will bear on questions of what happens to upper mantle structure and earthquake occurrence when a hot spot traverses through a region of continental crust. This research is a component of the National Earthquake Hazard Reduction Program. ***

119628474 Humphreys这项研究涉及完成爱达荷州Snake River Plain项目结果的分析。 该项目涉及1993年至1994年10个月内28个密封式便携式地震系统的地震数据的汇总和记录，以描绘蛇河平原上的蛇河上的地幔和地壳，这是一场火山特征，这是跨越美国西北部的超级范围的范围，这是在美国西北地区的更多需要的结果，而不是更多的实验。由于数据记录的成功率很高，并且在记录间隔内有大量可用地震事件。 当热点穿过大陆地壳区域时，结果将涉及上地幔结构和地震发生的问题。 这项研究是国家地震危害计划的组成部分。 ***
