Precaution fault zones designated by Matsuda (1981) are reevaluated using recently-obtained data on the late Quaternary slip-rate and from the result of excavation studies for faults of historical earthquakes. The precaution faults were defined as those with elapse ratio, E=t/R>0.5 (t: elapsed years since the last activity. R: average recurrence interval).<BR>The following three fault z o nes can be excluded from the previously-denoted precaution zones: The Arima-Takatsuki tectonic line (t/R=0.1∼0.4), which have moved in 1596. The Rokko-Awaji fault zone (t/R=0.0∼0.5), of which southern part moved in 1995 and northern part probably in 1586. The Atera fault zone (t/R= 0.3∼0.5 for M8.0 ), which have moved in 1586.<BR>The following fault zones are ascertained to be precaution faults. Segments of the Median Tectonic Line of central Shikoku to central Kii (t/R=0.5∼2.5 for M7.8). The Inadani fault zone (t/R>0.6∼1.6). The central part of Itoigawa-Shizuoka tectonic line (t/R=0.9), which moved about 1200 years ago. The Fujikawa fault zone (t/R>0.9∼1.4). The Kozu. Matsuda-Kannawa fault zone (t/R>1.0∼2.8).

The Itoigawa-Shizuoka tectonic line (ISTL), which is located between the NE and SW Japan arcs, is one of the most major tectonic lines in Japan. The N-S trending Kamishiro fault located in the northern part of the ISTL active fault system is an east dipping reverse fault. Near the southern part of the fault, the alluvial fan formed by a river flowing toward the southeast is tilted to the west by faulting. To reveal shallow subsurface deformation structure above a depth of 5 m, we carried out ground penetrating radar (GPR) profiling along two survey lines, whose lengths are 50 m and 130 m, respectively, across the fault. The GPR data was collected by common-offset modes using the control unit SIR-3000 (Geophysical Survey System Inc.) and the 200 MHz antenna Model-5106(Geophysical Survey System Inc.), and the station spacing was 0.01 m. The depth converted GPR sections after careful data processing are very concordant with the geological section based on drilling and trenching surveys conducted near the GPR survey. The GPR sections show deformation structure of the fan deposits in detail. The vertical displacement of the top of the fan gravel deformed by the Kamishiro fault is over 3.0 m during the last faulting event.

The Kamishiro fault is one of the major active faults constituting the Itoigawa-Shizuoka Tectonic Line (ISTL) in central Japan. The Kamishiro fault is an east-dipping reverse fault. This fault cuts and warped the young lake deposits (late Pleistocene and Holocene in age) in the Kamishiro basin. The slip rate on the Kamishiro fault near the surface has been estimated by Geo-Slicer and shallow drillings survey, but was found to be significantly smaller than the vertical slip-rate that was estimated from the displacement of the AT volcanic ash. We carried out a 55 m deep drilling and a seismic reflection profiling using S-waves in this basin to clarify the subsurface structure of the Kamishiro fault. As a result, it was clarified that the Kamishiro fault is associated with drag folding near the surface. If we take the drag folding into account, the overall rate of slip on the fault would be as high as 4.4-5.2mmlyr during the past 28ka.

The Hitoyoshi Basin is located at the southern part of Kumamoto Prefecture, southwest Japan. The basin has been considered to be a fault angle depression bounded by fault at the southern margin of the basin, named here the southern marginal fault of the Hitoyoshi Basin. This fault extends NE-SW direction for about 22 km, and has a sense of right lateral strike-slip with a northwest downthrown vertical component of displacement.
