Strain and ΔCFS by dike intrusion and faulting. a Dilatation by the Eq1 faulting at the depth of 0 km. Red and blue arrows denote the theoretical extensional and compressional strain axis, respectively, which were calculated from the dike intrusion and faulting model. The white bold rectangle shows the fault of the Eq1. b ΔCFS at the depth of 15 km by the Eq1. c The same as a but for the 2002 afterslip. The notation at the right side of the panel shows the parameter of the receiver-side fault, which was used for the calculation of the ∆CFS. d The same as b but for the 2002 afterslip. e The same as a but for the SW1. The fault parameters (strike, dip, length, width, and degrees of intrusion) are the same as the SW2. The white circles show the epicenters of earthquakes (M > 2.0 and depth < 30 km) that occurred on October 2002. The black solid line shows the dike of the SW1. f The same as b but for the SW1. The white solid line shows the dike of the SW1. g The same as a but for the SW2. The open circles show the epicenters of earthquakes (M > 2.0 and depth < 30 km) that occurred on April 2013. The black solid line shows the dike of the SW2. h The same as b but for the SW2. The white solid line shows the dike of the SW2
