Key Points

To describe the design, operational framework, and deployment of the Mexico City Seismic Alert System (Sistema de Alerta Sísmica, SAS) for providing advance warning against strong earthquakes originating along the Guerrero coast.
Field instrumentation utilizing a coastal network of digital accelerometers deployed along the Guerrero subduction zone to detect impending large-magnitude earthquakes.
Radio telecommunication relays integrated to transmit real-time trigger criteria and wave detection data to central processing facilities.
Rapid calculation algorithms engineered to estimate magnitude within seconds and broadcast automated alert signals to vulnerable metropolitan areas.
Established a functional seismic alert architecture capable of providing metropolitan Mexico City with roughly 60 seconds of early warning before destructive S-waves arrive from the Guerrero coast.
Successfully integrated automated broadcast mechanisms across schools, public transit systems, and radio broadcast networks to facilitate prompt emergency actions.
Demonstrated reliable system performance in distinguishing significant seismic events from minor tremors to prevent false alarms during operational monitoring.
