Fig. 1From: Estimation of convergence boundary location and velocity between tectonic plates in northern Hokkaido inferred by GNSS velocity dataTectonic map of northeast Asia. The red line indicates a plate boundary model (PB2002) by Bird (2003). Stars indicate the epicenters of large earthquakes along the eastern margin of the Japan Sea. The moment tensor solutions are from Fukao and Furumoto (1975) for (1) and (3), from Abe (1975) for (2), and from the Global CMT Project (2019) for (4)–(9). A black broken circle indicates the absence of large earthquakes. The study area is indicated by a black solid lineBack to article page
