9706690 Kellogg Using a combination of Global Positioning System (GPS) measurements, historical data, and viscoelastic modeling, The PI will determine the deformation on the White Wolf Fault, southern California. This fault was responsible for the 1952 Kern County Earthquake (magnitude 7.8). The research plan includes: (1) reoccupation of the previously studied geodetic network to establish the long-term deformation rates and examine the effects of the Northridge earthquake; (2) occupation of geodetic sites near the northern end of the fault to determine the strain associated with seismic activity in this region; (3) analysis of available geodetic data from 1952 and 1953 to determine the deformation associated with the Kern county earthquake, and (4) simulation of the deformation using a numerical model of a faulted, viscoelastic medium to determine the crustal rheology. ***

凯洛格 PI将使用全球定位系统（GPS）测量、历史数据和粘弹性建模的组合，确定加州南部白色沃尔夫断层的变形。1952年克恩县发生7.8级地震。 研究计划包括：（1）重新使用以前研究过的大地测量网，以确定长期变形率，并检查北岭地震的影响;（2）在断层北方端附近使用大地测量点，以确定与该地区地震活动有关的应变;（3）分析1952年和1953年的现有大地测量数据，以确定与克恩县地震有关的变形， (4)使用断层粘弹性介质的数值模型模拟变形，以确定地壳流变学。 ***
