Figure 3. Coulomb stress change imparted by the magnitude 7.4 earthquake to the surrounding faults, calculated using actual focal mechanisms. a) Coulomb stress change resulting from the magnitude 7.4 earthquake on the receiver fault that produced the magnitude 6.8 earthquake. b) Coulomb stress change resulting from the magnitude 7.4 earthquake on the receiver fault that produced the magnitude 5.8 earthquake. c) Coulomb stress change resulting from the combined effects of the magnitude 7.4 earthquake and the magnitude 5.8 earthquake on the receiver fault that produced the magnitude 5.2 earthquake. The colors of the focal mechanism solutions correspond to the calculated Coulomb stress changes. Data sources: Earthquake locations from GFZ; focal mechanisms and location of active faults and trenches from PHIVOLCS; SAR-derived topography from NAMRIA.
