Identification of multiple faulting events of the Median Tectonic Line active fault system in the Tokushima Plain, Japan, based on close-interval radiocarbon dating

Close-interval radiocarbon dating of terrestrial macrofossils from sediment cores across a fault is an instructive tool for identifying timing of multiple faulting events. We performed accelerator mass spectrometric (AMS) 14C measurements and high-resolution sedimentological analysis. At least six p...

Description
Summary:Close-interval radiocarbon dating of terrestrial macrofossils from sediment cores across a fault is an instructive tool for identifying timing of multiple faulting events. We performed accelerator mass spectrometric (AMS) 14C measurements and high-resolution sedimentological analysis. At least six paleoseismic events of the Median Tectonic Line active fault system in the Tokushima Plain, Japan, are detected during the last 16000 years: around 850 cal BP, 2850 cal BP, 5300 cal BP, 7500 cal BP, 9000 cal BP, 16000 cal BP.
