| Research Abstract |
We examined regional interaction among active reverse faults quantitatively, to better understand magnitudes and recurrence patterns of large earthquakes. We conducted intensive surveys on the WFZNB (western margin reverse-fault zone of the Nagano basin). Our results imply that recurrence intervals are relatively irregular for the latest four large earthquakes although coseismic vertical displacements are almost the same at individual sites. Further investigations are needed to examine paleoseismic relationship between the WFZNB and the northern part of the ISTL (Itoigawa-Shizuoka Tectonic Line) active fault zone.
