Fig. 3From: Spatiotemporal evolution of tremor activity near the Nankai Trough trench axis inferred from the spatial distribution of seismic amplitudesEpicenters, vertical cross sections and the histograms of longitudinal, latitudinal, and depth distributions of tremor locations determined herein between 1 December 2020 and 31 January 2021. Circles are tremor locations, and inverted triangles are DONET stations. The longitudinal and latitudinal histograms have bin sizes of 0.1\(^{\circ }\), and the depth histogram has bin size of 2 km. Color contours describes the shear stress accumulation rate at the plate boundary estimated by Noda et al. (2018)Back to article page
