The Wangsan Fault in the Gyeongju area shows the largest known displacement of about 28 m among the Quaternary reverse faults in South Korea. Recent optically stimulated luminescence (OSL) age data of the Quaternary deposits cut by the fault have been interpreted as suggesting that the time-averaged slip rate and maximum recurrence interval of the fault movement are 0.52 mma -1 and 50 ka, respectively. If considering the thickness of the Quaternary deposits exposed and assuming a uniform sedimentation rate, however, the slip rate and recurrence interval might be about five times higher and shorter, respectively.
