Seismic moment of past M ≥ 6 crustal earthquakes from 599 to 2020. a Moment distribution of earthquakes in 0.2º cells. Red circles indicate epicenters of earthquakes. b Moment evolution of earthquakes. Note that the seismic catalogue is based on historical documents for 599–1918 (Utsu., 1990; 2002) and instrumental seismograms from 1919 (Japan Meteorological Agency 2022)
