  1. 1GPS displacement at ICNS station taken from (Ohta et al. 2008). 2Displacement and tilt (SUF tilt) measured by the surface accelerogram at IWTH25. 3Displacement measured by the borehole accelerogram at IWTH25. 4Tilt measured by the tiltmeter at IWTH25. 5Tilt measured by the spatial derivative of surface and borehole displacements at IWTH25 (DIF tilt). 6Tilt measured by the spatial derivative between ICNS and IWTH25 (borehole). 7–9Predicted displacements and tilts at IWTH25 by the fault models of Ohta et al. (2008), Takada et al. (2009), and Suzuki et al. (2010), respectively. 10Predicted displacements and tilts at IWTH25 by the fault model of Suzuki et al. (2010) with fault 3 (conjugate fault) of Takada et al. (2009).
