In 1997, two strong earthquakes occurred on March 26 (M j 6.6) and May 13 6.4) in the northwestern part of Kagoshima Prefecture, Japan (termed 1997 Northwestern Earthquakes).However no seismogenic faults associated with these had previously been recognized at surface.
The 2000 Western Tottori Earthquake (Mw 6.6, Mjma 7.3) in Japan occurred an area where no active faults are known to exist. We examined the distribution, occurrence, paleostress field, and K–Ar ages of minor aftershock region this earthquake understand tectonics deformation process a blind fault area. Five stress stages were identified: NW–SE compressional strike-slip NE–SW extensional normal faulting field Stage 1; clockwise rotation ~ 40° between 18 16 Ma 2; N–S 3; state with σHmin (σ3)...
