- Abstract:
- Using high score No.1 remote sensing image and Googleearth image data,we carried out the interpretation of remote sensing work of the micro-topography(river,alluvial fan,ridges etc. )of Lenglongling Fault which is the seismogenic tectonics of Menyuan MS6.4 earthquake on Jan.21,2016. The study results have shown that the Lenglongling Fault has characteristics of typical left-lateral and strike-slip. The fault occurred 4 periods of fault activity since the late Pleistocene,and their displacement are 4 565 m,2 252 m,1 327 m and 710 m from the old to the new,which reflects the activity of fault is strong,but the amplitude of fault activity gradually decreases. Combined with aftershocks distribution and focal mechanism solutions,we judge that the Lenglongling Fault is the control structure of this earthquake,however,the seismogenic tectonics may be the secondary thrust north fault of Lenglongling Fault.
