RESEARCH ON METHOD TO SOLVE FAULT MOVEMENT AND
FAULT ZONE STRAIN USING CROSS-FAULT DEFORMATION DATA
First Crust Monitoring and Application Center, CEA, Tianjin 300180
Abstract A new method which could obtain the crustal horizontal strain and fault deformation from crossfault data is proposed. Using the crossfault baseline and leveling data at Tangshan seismostation during 1999 to 2012, the vertical deformation of the Tangshan fault is calculated with a presumption that the fault vertical activity is rigid body movement. And then assuming that the fault zone and its surrounding areas are uniform strain fields, the fault horizontal movement and the strain characteristics of the fault zone from the crossfault baseline data are separated, then the horizontal and vertical activity rate of the Tangshan fault, the strain characteristics and principal stress direction of the fault zone are solved.
Key words :
Tangshan fault
cross-fault deformation
baseline
leveling
strain stress
