| Abstract: | The typical earthquake disaster and its seismogenic mechanism in the meizoseismal regions of M7. 6 Lancangand M7. 2 Gengma earthquakes are introduced and analysed in this paper. Combining with the tectonic features in the earthquake regions, the difference of the tectonic activity between the two earthquakes is alsoshown in the paper: the strong strike offset feature of Muga fault for M7. 6 Lancang earthquake, while thedip-slip feature of Hanmuba fault for M7. 2 Gengma earthquake. The obvious difference in the displacementbetween Muga fault and Hanmuba fault probably related to the part adjustment and diversion for the principalcompressive stress axis in the focal area of M7. 2 Gengma earthquake. The M7. 6 Lancang earthquake triggered M7. 2 Gengma earthquake. |
