Present crustal deformation and stress-strain fields of North China revealed from GPS observations and finite element modelling

North China is located on the N–S seismic belt of mainland China and is characterized by dense faults and intense seismicity. We analyzed the current regional crustal deformation using GPS observations from 1999 to 2007 and 2011–2017. We then established a dynamic finite element model based on the geological structure, geophysical parameters, and GPS velocity constraints to analyze the strain-stress features. Finally, we discuss the rationality...
