The heavily-damaged area of this earthquake should be located between Jugan township of Wudu County and Pingding township of Zhouqu County. Its epicenter should be in the vicinity of Lianghekou in Wudu County with a magnitude of about 7-7 1/4 and an intensity of about IX-X. The major axis direction of the heavily-damaged area should be in the WNW direction that is approximately consistent with the strike of the middle-east segment of Diebu-Bailongjiang active fault zone, and the origin time should match up to that of the latest paleoearthquake event [before (83±46) B.C.] obtained by the trench investigation. Certain seismic rupture evidences are still preserved on this fault segment. Therefore, we propose on the basis of comprehensive analysis that the causative structure of the M 7-7 1/4 Wudu earthquake in 186 B.C. should be in the middle-east segment of Diebu-Bailongjiang active fault zone.展开更多

It was overturned by leaders from the State of Chu in 680 B.C. This bronze basin, the only unearthed relic from the State of Xi, is 21 centimeters in girth, has a lid with a bugle-shaped handle and two symmetrical handles on the sides. The bottom of the basin is engraved with the characters meaning "Xing, the king of the State Xi has this as his food basin."展开更多
