GPS约束下川滇地区主要断裂现今活动速率的估算方法
GPS-constrained estimate method of present-day slip rate along major faults of Sichuan-Yunnan region in China
摘要
Abstract
In order to obtain the long-term motions of blocks and contemporary slip rates along major bounding faults in Sichuan-Yunnan region, we built a GPS-constrained linear elastic block model with 24 blocks and eliminated the effect of internal deformation of each block. After the elimination of internal deformation effect, the results show that the RMSE of residual velocities decreased from 1.46 mm/a to 1.15 mm/a. Therefore, one should consider the elastic internal deformation effect when analyzing the motion characteristics of tectonically complicated region using block model.关键词
