汶川地震孕震背景与同震变化的铲形断层位错模拟
The Simulation on Listric-fault Dislocation Background and Co-seismic Deformation of the Wenchuan Earthquake
摘要
Abstract
Using long-leveling section observation data crossing Longmenshan fault during the period of 1983-1997 and 1997 (or 2007)-2008, aided by positive and negative dislocation model of pure thrust and spade-fault, in combination with the method for grid-searching and testing, the authors simulated the locked energy background before the Wenchuan Ms8.0 great earthquake of Sichuan Province on 12 May, 2008 and its co-seismic deformation. The energy accumulation before this earthquake and co-seismic rebounding of Central Longmenshan fault are revealed to some extent.关键词
