Fig. 4: Distributions of P axis plunges, T axes, and ΔCFS around the southern edge.
From: Stress relaxation arrested the mainshock rupture of the 2016 Central Tottori earthquake

a Filled circles indicate the P axis plunges of aftershocks occurring within a 2 × 2 × 1 km3 volume centred at the estimated fault edge at the depth of 5 km. Normal faulting aftershocks are characterised by P axis plunges greater than 60°. T axes are also projected onto the horizontal plane. ΔCFS are denoted for normal faulting aftershocks with a fault strike of N110°E, a plunge of 45°, and a slip direction of −90° with black contours of 3, 4, 5, and 6 MPa and grey contours of 0, −3, and −6 MPa. b ΔCFS for the same strike-slip fault as the mainshock. The other items in the figure are the same as for (a). The red line indicates the estimated fault plane at the depth of 5 km.
