抄録

The Arima-Takatsuki fault zone consists of a series of ENE-trending right-lateral strike-slip faults along the northern margin of the Osaka plain. This fault zone is considered to have ruptured during the 1596 Keicho-Fushimi earthquake based on paleoseismic trench excavations across the fault zone conducted by the Geological Survey of Japan and numerous liquefaction features on archaeological sites in Kobe-Osaka-Kyoto areas. The surface offset during the earthquake was estimated to have been about 3 m based on offsets of rice-paddy dikes at two localities. In order to search for more data on the surficial slip during the 1596 earthquake as well as evidence for prehistoric earthquakes, we have interpreted large-scale aerial photographs and conducted geomorphic field investigations. We have identified several localities along the fault zone where geomorphic and/or artificial features are systematically offset about 3 m, confirming previous estimates of the surficial slip during the 1596 earthquake. Larger displacements of older geomorphic features also suggest repeated right-lateral slip on the fault zone in late Holocene time.
