The Outcrop of the Median Tectonic Line Shobudani Fault which Appeared in the Construction Spot of Hashimoto City in Wakayama Prefecture, Southwest Japan

Abstract

Median Tectonic Line outcropped at Suda town in Hashimoto City, Wakayama Prefecture. In this outcrop, Izumi Group thrust up Shobudani Group. This thrust fault is Shobudani fault that acted at Early Quaternary. The short paper describes this outcrop, and is an examination of continuousness and the activity of the fault. The Shobudani fault perhaps converges with northern Gojodani fault in a deep part under the ground, and probably the fault activity becomes dull in about 0.8-0.7 Ma.
