2. Figure 2. Surface faulting of the 2016 Kumamoto earthquakes on known active faults. Along the Futagawa fault zone, about 30 km long, a series of surface faults are found. The maximum faulting is 2.2 m right-lateral slip at Mashiki town, Dozon area. Photo taken on 2016, May 14th by　Naoshi Hirata.
