The authors used the h-value and b-value to trace the M_S5.8 Yingjiang earthquake sequence and found that: 1) h-value after the Yingjiang M_S4.8 earthquake on January 2 was 0.6, and the one after the Ms4.8 earthquake on February 1 was 0.8; and 2) b-value after the M_S4.8 Yingjiang earthquake on January 2 was 0.77, and the one after the M_S4.8 earthquake on February 1 was 0.82, according to these two high b-values. The M_S5.8 earthquake resulted from the left-lateral, strike-slip faulting of the Dayingjiang Fault. Calculating the focal mechanisms of thirteen M≥3.6 events of the sequence, the authors found that P-axis and T-axis greatly changed.
