Map showing study area. a Tectonic setting of Japanese islands. The Kinki region, which includes Awaji Island, is shown in blue. b Enlarged map of red rectangle shown in a depicting the 2013 Mw5.8 Awaji Island earthquake. Red lines show active faults after Nakata and Imaizumi (2002). Circles represent M0 + seismicity shallower than 20 km determined by the Japan Meteorological Agency (JMA) during the period from 1 January 2003 to 12 April 2013 (i.e., the day before the Awaji Island earthquake). The ‘beach balls’ represent the centroid moment tensor solutions by JMA. The surface projection of the fault model of the Kobe earthquake (Ide and Takeo 1997) is indicated by a rectangle. Topography is based on a 250 m grid digital elevation model published by the Geospatial Information Authority of Japan
