Earthquake swarm activity. a Thin lines show a northeastern corner of the SSE fault assumed in Fig. 4a. A rectangle drawn by a bold line indicates the area where the earthquake swarm activity was observed. Dots within the rectangle are the epicentres determined by the Japan Meteorological Agency between 2000 and 2022. b The cumulative number of earthquakes within the rectangle in (a). (c) Magnitude−Time plot of the earthquakes within the rectangle in (a). d Space−Time plot along AB in (a). e Space−Time plot along CD in (a). Broken lines in red color show the migration of earthquakes from 2004 to 2006
