Understanding the kinematic rupture process of the Kumamoto earthquake

Using GPS, strong motion, Synthetic Aperture Radar images and surface offset data, this paper seeks to understand the kinematic rupture process of the 2016 Kumamoto earthquake. The authors use a joint inversion to resolve the kinematic rupture process of the mainshock and co-seismic displacement of the two major foreshocks. The results show an abrupt termination at the eastern end of the mainshock, chiefly constrained by the geodetic data, which is consistent with previous finite fault inversion results. The authors also analyze the possible mechanisms that govern the rupture termination. Overall, this paper not only offers insights into the Kumamoto earthquake but also offers a sophisticated modeling approach for understanding earthquake relocation.
