Unraveling Seismic Complexity: Repeating Rupture Patterns and Varied Seismogenic Environments in the Mexico Subduction Zone
Description:
Accurately determining the locations of repeating or quasi-repeating large earthquakes allows for a more reliable estimation of recurrence periods and the identification of seismic gaps. In this study, we systematically investigate the complexity of earthquakes within the Mexico Subduction Zone. Using waveform comparisons, we identify six sets of repeating rupture patterns, and subsequently refine the slip models of historical events through joint finite fault inversion method. Our findings indicate significant differences in tectonic activities between the northern (Jalisco-Michoacan) and southern (Guerrero-Oaxaca) segments of the Mexico Subduction Zone. By clarifying these differences, we provide valuable insights for future seismic risk assessments along the Mexico Subduction Zone, enabling a more accurate and region-specific understanding of the potential impact of earthquakes. This research serves as a foundation for enhancing preparedness measures and resilient infrastructure development, particularly in regions where the seismogenic environment poses unique challenges.
