| Abstract: | The 1933 M7.5 Diexi, Sichuan, earthquake in western China caused tremendous loss of human lives and property damage. Because of data shortage, the seismogenic structure and focal mechanism of this earthquake are still not well constrained. Having collected worldwide seismic records of this earthquake, among which some polarities of the first arrival phases were picked, we relocated this earthquake and obtained the fault plane solution through grid search. The relocated epicenter of this earthquake is at (31... |
