Map of the study area. Red and blue stars denote the hypocenters of the M 6.5 event (April 14, 2016, 21:26 JST) and the M 7.3 event (April 16, 2016, 01:25 JST), respectively. Red circles denote the hypocenters of events (M ≥ 1) in the period between the M 6.5 event and the M 7.3 event, which were determined by the NIED Hi-net. Blue circles denote the hypocenters of aftershocks (M ≥ 1) 1 month after the M 7.3 event, as determined by the NIED Hi-net. Violet lines denote the surface traces of active faults (AIST 2007). Gray lines denote the rough locations of the Hinagu fault zone (Takano-Shirohata segment, Hinagu segment, and Yatsushirokai segment) and the Futagawa fault zone (Futagawa segment, Uto segment, and north coast of Uto Peninsula segment) (ERC/HERP 2013)
