AB: By discriminating from the alluvial deposits in the excavations, we identify two events at the Rusui site in the Longitudinal Valley, eastern Taiwan. Radiocarbon dating revealed an earthquake event which occurred with an age equivalent to or younger than BP 500-330 besides the recent 1951 earthquake. The excavation has the amount of vertical displacement about 2.5 m by an east-dipping reverse fault, and the penultimate event shows 0.75 m vertical offset. The minimum vertical uplifting rate is 7 mm/yr.
