Fig. 4From: Estimation of convergence boundary location and velocity between tectonic plates in northern Hokkaido inferred by GNSS velocity dataSeismicity map of northern Hokkaido. The epicenters of earthquakes from 1997 to 2016 are plotted based on the catalog obtained from the Japan Meteorological Agency (2019). The solid lines indicate the estimated location of the boundary in each area (same as in Fig. 3a)Back to article page
