A new sampling technique using ten meter long geo-slicers in addition to drilling was applied across the Kamishiro fault, northern part of the Itoigawa-Shizuoka Tectonic Line. Slip rates of the Kamishiro fault in the Kamishiro Basin is estimated be ca.1.5mm/yr since about 18,000 years B. P., based on the interpretation of geological section in size of 20m×25m and 14C dating of woody and peaty materials sampled.
