MCS profiles (time sections) for ECr6 and ECr22 near the active seismic area around Miyako Seamount. Black dots show epicenters with focal depths ≤ 30 km determined by the JMA (1923–2018, February) in the bathymetric map. Pink focal mechanisms are from the F-net CMT Catalog by NIED (1997–2018, February), and blue are from the GCMT Catalog (1976–2018, February). Black squares and a red asterisk in the topographic maps (center) are positions of the OBSs and the epicenter of the 1938 M7.2 Miyako-jima–Hokusei-oki Earthquake, respectively
