英文摘要	We investigated space-time patterns of Quaternary fault activity of the Keumwang Fault developed in the Jincheon-gun and Eumseong-gun regions, Chungcheongbuk-do, using ESR dating method. The fault core which consists of 90 cm thick fault gouge was developed between the cataclasite derived from Cretaceous biotite granite and Cretaceous mudrocks in the study area. The fault plane developed between cataclasite and fault gouge strikes N66 degrees E and dips 70 degrees SE and the fault plane between mudrocks and fault gouge strikes N60 degrees E and dips 65 degrees SE. Some subsidiary faults including R-shear, R-shear, P-shear and Y-shear were developed in the damage zone of Cretaceous mudrocks. ESR dates from the main fault strand and subsidiary faults range from 560 ka to 140 ka. The result demonstrates that the long-term cyclic fault activity of the Keumwang Fault in the study area continued into the Pleistocene. Similar cyclic patterns of fault activity were presented in previous studies of the Northeast region of the Keumwang Fault. ESR ages also indicate that fault activities appear to migrate along the strike of the Keumwang Fault.
