Analysis of Tangshan Cross-Fault Deformation Using Particle Filter

Based on the dynamic system model of across faults deduced by YOU Li-lan,using particle filter based on residual resampling method, we analyze the cross-fault leveling data of Tangshan station combing with auxiliary observations such as temperature, precipitation and so on. Assuming that the deformation observations are influenced only by these observed environmental factors (such as precipitation and the temperature), the influence quantity of these environmental factors and the fault activity can be obtained.
