| Abstract: | According to thesection of the big trenching on the Xianshuihe fauh, the space and timefeatures of deposit and accumulation since the later period of Epipleistocene were researched inthis paper. Thereby,we analysed and determinged the occurrence time of each historicalearthquake. We found eleven historical earthquakes from the trenching(including the 1993 M= 7.6 Luhuo earthquake).Furthermore,we discussed the stable mark of historical earthquake,theformation of structure wedge and the history of the fault rub movement.The results are of goodsignificance for reseaching the repeat interval of historical earthquakes and eveluating the stabilityof an area. |
