Displacement (EW, NS, UD), differential stress (S-DIF), maximum principal stress (S-MAX), and minimum principal stress (S-MIN) distributions due to the 2016 Kumamoto Earthquake on the spherical surface of the Aso magma system. In this calculation, the magma system is assumed to be a 1-km-radius sphere 6 km beneath the Nakadake crater. The squares indicate the seismic faults (F1, F2, F3, and F4) obtained from the SAR analysis in the previous section. Thin lines indicate the axes of maximum and minimum principal stress, respectively
