Latest rupture event of the Mino Fault, in the Median Tectonic Line active fault system, east Shikoku, southwest Japan



Latest rupture event of the Mino Fault, in the Median Tectonic Line active fault system, east Shikoku, southwest Japan



Chigaku Zasshi = Journal of Geography 111(5): 661-683



The Median Tectonic Line (MTL) active fault system is one of the most active intraplate faults in Japan. The fault system, which is more than 300 km long, is a right-lateral strike-slip fault with an average slip rate of 5-10 mm/y in east Shikoku. The 13.5-km-long Mino fault of the MTL active fault system is located at the western part of Tokushima Prefecture in east Shikoku. We carried out trench excavation surveys of the Mino fault at Ueno in Mino Town and Ikenoura in Mima Town. Both sites are situated at fault depressions formed on the middle and lower terrace surfaces by the activity of the Mino fault. Fault depression deposits consist of younger and finer grained layers with abundant (super 14) C dating samples. We inferred the dates of faulting events from upward fault terminations on the trench walls. At Ueno, it is recognized that the latest rupture event occurred between 1,295-1,390 cal A.D. and 1,660-1,950 cal A.D. (190+ or -50 years B.P.). Multiple faulting events are also suggested after K-Ah ash fall (about 5,200 B.C), because the ash layer steepens to near vertical. At Ikenoura, the latest rupture event is estimated to have occurred after 1,525-1,660 cal A.D.
