Late Quaternary displacements along the Zunduk fault according to ground-penetrating radar and morphostructural analysis (northwestern coast of Lake Baikal)

The article considers the results of GPR studies Zunduksky fault section activated between Cape Oto-Khushun and Zunduk River, in late Quaternary. aim this work is to clarify kinematic type, determine vertical displacement amplitudes, dip angles active Quaternary, as well maximum magnitude earthquake that could occur a result activation fault. was carried out by OKO-2 with shielded antenna AB-90 ABDL-Triton. In addition main method, morphostructural analysis ledge used. As performed, it found Late Quaternary under tectonic extension predominant kinematics. one-act displacements along seismic fracture change from SW NE 6.9 1.6 m. When formed, plastic component had certain value, contribution which 18 78 % total displacement. Paleo-earthquake magnitudes calculated are Mw = 7.3 Ms 7.5.
