AbstractThe tidal Coulomb failure stresses (TCFS) on various kinds of seismic faults are calculated and their latitudinal variation characters are studied. We compute tidal Coulomb failure stresses at shock‐occurring times on 20395 earthquake faults and analyze the latitudinal distribution of various kinds of real seismic faults that are slip‐encouraged by TCFS. The results show that the features of tidal failure stress are closely correlated with fault type, fault strike and fault location. The TCFS variation properties are different on various kinds of fault during the same period. And there are obvious differences in amplitudes and signs of TCFS on same kind fault in different latitudinal regions. For normal faults, the tidal slip‐encouraged effects are outstanding in low and middle latitudinal regions; for thrust faults, the tidal slip‐encouraged effects are obvious in middle and high latitudinal region; for strike‐slip fault, the tidal slip‐encouraged effects are reducing with latitude increasing.
