THE RUPTURE MECHANISM OF THE ZHAOTONG EARTHQUAKE OF 1974 IN YUNNAN PROVINCE

ZHU CHENG-NAN CHEN CHENG-ZHAO (The Seismological Brigade of Kunming, National Seismological Bureau)  
On May 11, 1974, an earthquake of magnitude 7.1 occurred in the Zhaotong County, Yunnan Province. The epicenter is located in the mountainous region on the southern bank of lower Jinsha RiverIn this paper, by analyzing the geodetic data in and around the epicentral region, a thrust fault pattern of focal rupture has been established from the rela-tionship between rupture and strain. Based on intensity attenuation and after-shock distribution, we obtain the parameters of a rectangular slip fault model, and by applying the analytical expressions for the displacement field of a finit-slip inclined fault given by Mansiha and Smylie, the average dip-slip dislocation is calculated. The results are as follows: fault strike, N6°W; dip direction N84°B; dip angle, 60°; length of fault plane 20 kms, width 30 kms; depth of the top of the fault, 2.5 kms below the surface; average dislocation of dip-slip, 2.8 m; seismic moment, 5.4 × 1026 dyne · cm; stress drop, 51 bars; lower limit of the strain energy released, 1.2 × 1023 ergs.The authors also briefly discuss the nodal plane solution based on P waves and the tectonic conditions relating to the occurrence of the earthquake. Finally some macroseismic phenomena are explained.
