Crustal Deformation Near the White Wolf Fault, Greater Los Angeles Region Using Global Positioning System Observations and Viscoclastic Modeling

9706690凯洛格使用全球定位系统测量、历史数据和粘弹性模型的组合，PI将确定南加州白狼断层的形变。该断层是1952年克恩县7.8级地震的罪魁祸首。研究计划包括：(1)重新占用以前研究过的大地测量网络，以建立长期形变速率并检查北岭地震的影响；(2)占领断层北端附近的大地测量站点，以确定与该地区地震活动有关的应变；(3)分析1952-1953年的现有大地测量数据，以确定与克恩县地震有关的形变；以及(4)使用断层粘弹性介质的数值模型模拟形变，以确定地壳流变性。***

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. ***
