Figure 3. Time-sequence Coulomb stress change maps using the method of Toda et al. (2011) of earthquakes with magnitude 6.0 or greater generated by different segments of the left-lateral Philippine Fault in 10-year intervals from 1973 to 2023. Refer to Figure 1 for other place names and labels. Data sources: Jarvis et al., 2008 for SRTM topography; Weatherall et al., 2020 for bathymetry; GCMT, USGS and PHIVOLCS for earthquake data. The Generic Mapping Tool (Wessel and Smith, 1995) was used to generate the map. See text for discussion. Credit: Aurelio, et al., 2025, CC BY-NC-ND 4.0
