Fig. 8

Spatial relations of the NW-trending minor surface ruptures with aftershocks, focal mechanisms, and stress imparted from the Kumamoto main shock. a Aftershocks from the Japan Meteorological Agency catalog until September 18, 2016. b Focal mechanisms of the larger aftershocks determined from National Research Institute for Earth Science and Disaster Resilience (2016). c Coulomb stress change resolved onto NW-striking normal faults. d Coulomb stress change resolved onto NW-striking thrust faults. In both c and d, the source fault model of the Geospatial Information Authority of Japan (2016a) as gray rectangular is used for the stress calculation with apparent coefficient of friction 0.4 at a depth of 2.5 km. Receiver fault that Coulomb stress is resolved is shown as the red line on the beach ball and in the parentheses (strike/dip/rake) on each panel
