摘要
Abstract
With multifunction instrument V8 generated by Phoenix Company in Canada, the authors carried out magnetolelluric sounding study in the middle section of Longmenshan structural belt, and used advanced data processing and interpretation of electromagnetic technology to analyze magnetoteiiuric sounding (MT) profile data. At the same time, the profile was analyzed by the qualitative analysis method (Mohr circle analysis, polarization diagram analysis) and the interpretation of magnetoteiiuric sounding, ft is concluded that the overall performance of the profile is two-dimensional, and the anisotropy and three-dimensional nature are relatively strong in the fracture sub-region. It is also inferred that the source location of the Wenchuan Magnetude-8 Earthquake that occurred in May 12, 2008 was in the footfall of Yinxiu fault.关键词
