The Median Tectonic Line (MTL) is the largest crustal break in southwest Japan, which bisects the island arc into the old terranes intruded by igneous rocks in the Inner Zone and partly metamorphosed accretionary complexes in the Outer Zone (Figure 1;). It has a period of activity as long as m.y. and highly complicated change in slip by: 3.   The Median Tectonic Line has intensified dextral motion since 2 Ma, with a northward shift of its active trace of as much as 10 km, accompanied by the formation of rhomboidal basins in Central Kyushu. Crustal rotation and incipient rifting has also occurred in South Kyushu and the northern Okinawa Trough over the past 2 million by: The Median Tectonic Line has intensified dextral motion since 2Ma, with a northward shift of its active trace of as much as 10km, accompanied by the formation of rhomboidal basins in Central Kyushu.

Abstract. The origin of the curvature of the Median Tectonic Line (MTL) in southwest Japan is still controversial. In order to investigate its formation, we carried out a paleomagnetic study in the Nohi area, north of the curved part of the MTL in the eastern part of southwest Japan. More than paleomagnetic samples were collected at 35 sitesCited by:   The relationship between the slip activity and occurrence of historical earthquakes along the Median Tectonic Line (MTL), together with that of the fault systems extending eastward has been examined. The MTL is divided into three segments, each containing diagnostic active faults. No historical earthquakes have been recorded along the central segment, although the segment has faster Cited by: Since the Hyogo-ken Nanbu earthquake, the importance of estimating strong seismic motion near a fault has been more keenly recognized. Therefore, some evaluating methods of strong seismic motion have been proposed and improved in a decade. To assume a precise fault model is one of the most essential factor in the process of evaluating strong seismic motion. We need the precise 3-D fault Author: M. Ikeda, T. Takahashi, Y. Ohno, N. Nishizaka, S. Kobayashi, T. Hasegawa, K. Hatakeyama, S. Hasegawa. The Median Tectonic Line active fault system (MTLAFS) is the longest and most active arc-parallel, right-lateral, strike-slip fault system in Japan. The stress conditions along the MTLAFS change from transpression on eastern Shikoku Island to transtension on Kyushu Island.

The Median Tectonic Line (MTL), SW Japan, is the largest on-land fault in Japan with a length of > km. Application of Raman CM thermometry to pelitic schist adjacent to the fault reveals the.   The Median Tectonic Line (MTL) in Southwest Japan, a major east‐west trending arc‐parallel fault, has been defined as the boundary fault between the Cretaceous Sambagawa metamorphic rocks and the Ryoke granitic and metamorphic rocks, which are unconformably covered by the Upper Cretaceous Izumi : Y.

The MTL, which has a length of more than km, is the largest tectonic line in southwest Japan, and its eastern portion has moved as a right‐lateral fault with a reverse‐fault component during the : Shigekazu Kusumoto, Keiji Takemura, Yasuto Itoh.
