Abstract:
The study "Interplay of slow-slip faults beneath Mexico City induces intense seismicity over months" analyzes how slow-slip movements in underground faults beneath Mexico City interact and generate prolonged seismic activity. By combining geodetic and seismological data, the authors demonstrate that these slow-slip events can trigger minor earthquakes over months, revealing a key mechanism in the region’s seismicity.
Description:
"Interplay of slow-slip faults beneath Mexico City induces intense seismicity over months" is a 2025 article published in Tectonophysics that investigates the relationship between slow-slip phenomena (gradual fault displacements) and persistent seismicity in the Mexico City metropolitan area. Through the analysis of GPS data and seismic records, the study identifies how the interaction of multiple faults in the lower crust and upper mantle releases energy over extended periods, generating seismic swarms. The findings suggest these processes are critical for understanding seismic hazards in regions with complex subduction systems, such as the Cocos Plate. The research provides evidence to improve predictive models and risk assessments for vulnerable urban areas.
