Keywords:ISTL, kamishiro fault, trench servey

The Kamishiro fault is located in the northernmost part of the 150-km-long Itoigawa-Shizuoka Tectonic Line (ISTL) active fault zone, central Japan. Immediately after the destructive Mj 6.7 earthquake of November 22, 2014, which occurred in the north-ern part of the Nagano Prefecture, we conducted trench survey across the northern part of the reverse-faulting Kamishiro fault.
