陕西高陵M4.4地震前后断裂活动垂直形变特征综合分析
Comprehensive Analysis of Fault Vertical Deformation before and after Gaoling M4.4 Earthquake in Shaanxi Province
摘要
Abstract
Before the Gaoling earthquake,cross-fault vertical deformation within 100 km ranges on the periphery of the epicenter showed no abnormal changes.Although the earthquake did not cause coseismic deformation of active faults,it led to fault instability.Fault creep intensified under the continuous action of aftershocks,and eventually caused about 3 mm permanent vertical deformation on the Lingkou cross-fault site.We speculate that the occurrence of earthquakes is connected with activities of Weinan tableland front fault.关键词
