【Abstract】 Based on the regional structural background and the active structure in Gonghe basin, the distribution characteristics and many kinds seismic parameters of outhquakes occurred in Gonghe basin weresynthetical analysed. And proceed to discuss the seismogenic structure. The authors think that the F1and F2 hidden faults in the direction of NW are two seisthogenic faults mainly in Gonghe basin.更多还原
