Abstract

Earthquakes induced by water injection appeared in the border area of Changning, Xingwen and Gongxian counties, Sichuan Province since April, 2006. Up to April 30, 2013, 16 M_L≥4.0 earthquakes occurred and the maximum is M_L=5.2 on April 25, 2013. In this paper, the earthquake focal mechanism changing process of Changning M_L≥3.0 earthquake sequence is studied by calculating correlation coefficient of body wave spectral amplitudes, and the results show that focal mechanisms of sequence events are scattering, furthermore, 12 M_L≥4.0 earthquakes' focal mechanisms are calculated by CAP method and they are in disorder also. The following analyses believe that water injection causes the pore pressure of rock body increasing as well as the friction coefficients of pre-existing fault planes decreasing, and those 2 factors lead to Coulomb stress change Δσ_f increasing, thus induce earthquakes' occurrence. Therefore, the earthquakes induced by water injection occur without obvious enhancement of regional tectonic stress intensity, and there are no obvious restraining effects on the rupture directions of the earthquakes. As a result, the focal mechanisms of those earthquakes appear scattering.
