            The authors investigated fault interaction through elastic stress transfer among a
          sequence of moderate-magnitude main shocks (5 < Mw < 6) which ruptured distinct
          normal fault segments during a seismic sequence in the Umbria-Marche region
          (central Apennines).They also model the spatial pattern of aftershocks and their
          faulting mechanisms through Coulomb stress changes. They found that of the 1517
          available aftershocks, 82% are located in areas of positive stress changes for
          optimally oriented planes (OOPs) for coulomb failure. However, only 45% of the
          322available fault plane solutions computed from polarity data are consistent with
          corresponding focal mechanisms associated with the OOPs.
            Kuo-Fong Ma also used Coulomb stress changes in Chi-Chi, Taiwan, earthquake.
          We may compare two with the similar method to the different area and takes
          advantage of this understanding Coulomb stress changes
