| 摘 要： | Basined on comprehensive prospecting and investigation, the authors have ascertained that the 1679 San-he-Pinggu M = 8 earthquake occurred in the intersection region of active faults having deep-seated structural background. The NE-trending New Xiadian Fault, which was characterized by dextrall tensile-shear dislocation, was the seismogenic fault of the 1679 M = 8 earthquake. It is suggested that the macroscopic epicenter of the earthquake should be located in Pangezhuang area, where the vertical displacement of seismic faul' was up to 3.16m. According to the average seismic slip rate in this area, and the displacement value of earthequake with a certain magnitude, the recurrence interval of M = 7.5, M=7.0 and M = 8.5 earthquakes in the magistoseismic area of 1679 M = 8 earthquake on Xiadian Fault Zone have been estimated to be 3800,1750, and 800 years (the lower limit), respectively

The NE-trending New Xiadian Fault, which was characterized by dextrall tensile-shear dislocation, was the seismogenic fault of the 1679 M = 8 earthquake. It is suggested that the macroscopic epicenter of the earthquake should be located in Pangezhuang area, where the vertical displacement of seismic faul' was up to 3.16m. According to the average seismic slip rate in this area, and the displacement value of earthequake with a certain magnitude, the recurrence interval of M = 7.5, M=7.0 and M = 8.5 earthquakes in the magistoseismic area of 1679 M = 8 earthquake on Xiadian Fault Zone have been estimated to be 3800,1750, and 800 years (the lower limit), respectively. |
