Abstract

The accurate investigation on the coseismic displacement attenuation pattern plays an important role in seismic intensity zoning. A new model combining the Logistic Power and Cosine model is proposed in this paper to evaluate the correlation between coseismic displacement and epicentral distance and rupture angle. The presented model is tested and validated using the high-rate GPS array displacement observables associated with Japan Mw 9.0 earthquake. The computation results show that the Logistic Power model is feasible to characterize the pattern between the coseismic displacement and epicentral distance, and the Cosine model between the coseismic displacement and rupture angle.
