Keywords:Itoigawa–Shizuoka tectonic line active fault system, East Matsumoto Basin fault, active fault, seismic reflection profiling, subsurface structure

We carried out P-wave seismic reflection profiling to reveal the subsurface structure across the northern central Itoigawa–Shizuoka tectonic line active fault system. Obtained migrated depth-converted section has shown a steeply (about 75 degree) eastward dipping fault.
