Fig. 1From: Shear wave splitting and seismic velocity structure in the focal area of the earthquake swarm and their relation with earthquake swarm activity in the Noto Peninsula, central JapanGeological map modified from Sawada et al. (2011). Red thick and thin lines denote the active and non-active faults, respectively. The rectangle denotes the spatial range of Fig. 5b. The ellipse with broken line shows the approximate location of the inherited caldera suggested by the gravity anomaly (see Fig. 3a). The moment tensor solution (NIED, 2023) of the M6.5 earthquake is shown on the rightBack to article page
