The Eastern margin of the Yokote Basin Fault Zone (EYBFZ) is one of the seismogenic reverse faults that developed in Northeast Japan, generating the 1896 Rikuu Earthquake (M7.2). The EYBFZ is divided into range boundary fault (Kawaguchi Fault) and frontal fault. The major segment of the frontal fault consists of three faults : the Shiraiwa Fault, the Ota Fault, and the Senya Fault, at which coseismic surface ruptures with irregular and highly sinuous traces, gaps and echelon steps occurred during the 1896 Earthquake. In the study area, the irregular coseismic surface ruptures probably originate from differences in fault geometries and sedimentary conditions, which are associated with thrust-front migration in the Quaternary. We discuss the relationships among fault traces, geomorphic displacements, and fault geometries on the Senya Fault and the Kawaguchi Fault, based on data from high-resolution seismic reflection profiling, investigations into tectonic geomorphology and structural geology with the help of the balanced cross-section method.<BR>The seismic image obtained shows changes of geomorphic and geologic features around the Senya Hills expressed as differences in faulting geometries along the Senya Fault and the Kawaguchi Fault. In fact, the Senya Hills are situated as an unsymmetrical ordering.The disparity in the timing of thrust-front migration affects the development of fluvial surfaces, which are related to the appearance of the fault scarp on the surface. That is why, in the central portion of the Senya Hills, the Senya Fault is a typical emergent thrust with flat-ramp structures associated with the uplifting and the back-tilting of late Quaternary fluvial terraces. On the other hand, in the northern portion, the Senya Fault is a concealed thrust with step-like geometry and prominent folding and small faults in the hanging wall. The small faults infer the structure of the tectonic scarp and short wavelength deformation on the surface. This means that the Senya Fault at the central portion preceded the northern portion as an emergent fault. Moreover, fault traces show different dips between central and northern portions. The dip of the central portion is lower than that of the northern portion.<BR>By restoring the balanced cross-sections and assuming the uniform net-slip rate, the initial thrusting along the boundary faults is retroactive to 2.02.6 Ma at the central portion and 1.8 2.3 Ma at the northern portion. The initiation of thrust front migration from the boundary faults to the frontal faults is ca.1.6 Ma at the central portion and 0.6Ma at the northern portion.

We conducted a tectonic geomorphological survey along the northern part of the Itoigawa-Shizuoka Tectonic Line (ISTL) with support from the Ministry of Education, Culture, Sports, Science and Technology of Japan as one of the intensive survey on ISTL fault system. This survey aims to clarify the detailed distribution of the slip rates of this fault system, which provides the essential data set to predict the coseismic behavior and to estimate the strong ground motion simulation. In order to achieve this purpose, the active fault traces are newly mapped along the northern part of the ISTL through interpretations of aerial photographs archived in the 1940s and 1960s at scales of 1: 10,000 and 1: 20,000, respectively. This aerial photo analysis was also supplemented and reinforced by field observations.<BR>One of the remarkable results by using this data set is a large number of, here 84, photogrammetrically measured landform transections to quantify the tectonic deformations. We could calculate vertical slip rates of the faults at 74 points, based on the estimated ages of terraces (H: 120 kyrs, M: 50-100 kyrs, Ll: 10-20 kyrs, L2: 4-7 kyrs, L3: 1-2 kyrs). The vertical slip rates distributed in the northern part of the study area show 0.2-5.5 mm/yr on the L terraces (less than 20 kyrs) and 0.05-0.9 mm/yr on the M and H terraces (more than 50 kyrs). The vertical slip rates of the faults located in the central and southern part of the study area are 0.2-3.1 mm/yr.

The North Matsuda fault in the Kozu-Matsuda fault zone is one of the active fault system, showing the largest vertical component of slip rate onshore Japanese islands. The Kozu-Matsuda fault system is considered as a part of the northern margin of the Philippine Sea plate. It is necessary to obtain the horizontal shortening component of slip rate of the North Matsuda fault for a better understanding of active tectonics in the northern margin of the Philippine Sea plate. To reveal the subsurface structure of the North Matsuda fault, high-resolution shallow seismic reflection survey with about 3.2 km line length was carried out across the fault, A kind of accelerated weight drop system named as Yuatsu Impactor (JGI Inc. ) was used as seismic source which has wide band frequency spectrum. Both the standard shot intervals and group intervals of geophones were 10 m. The Sakawa River near the center of the line obstructed both shooting and geophone setting, and the half of the line in the Matsudayama Mountains was severely crooked. Although such a bad survey conditions, the seismic section after careful data processing shows a drastic structural change and a north dipping thrust fault with 18 degrees near the Sakawa River, which is suggested as the North Matsuda fault. The fault trace revealed by a result of the seismic reflection survey is exactly located along the Sakawa River.
