MECHANISM ANALYSIS OF VERTICAL UPLIFT OF CRUST IN THE WEST OF LONGMENSHAN BEFORE WENCHUAN Ms8.0 EARTHQUAKE
|
Abstract:
The mechanism of the vertical uplift of crust in the west of Longmenshan before Wenchuan Ms8.0 earthquake has been debated through constructing the 2-D FEM model for the profile across Longmenshan fault,which is based on the velocity field that had calculated from the GPS observations and the result of seismic tomography obtained by Wu Jiangping et al.In addition,the effect of crustal inhomogeneity on the vertical uplift has been discussed as well.We concluded that the existence of the low velocity anomaly ...
