Mexico expands seismic monitoring network with 58 new stations
The Universidad Nacional Autónoma de México (UNAM) is leading an expansion of the Mexican Seismic Network, adding 58 new monitoring stations nationwide. Of these, 38 will be operated by the Servicio Sismológico Nacional (SSN) and 20 by the Unidad de Instrumentación Sísmica of the Instituto de Ingeniería (II). The new sites cover previously under‑instrumented northern regions, including the Baja California peninsula, Sonora, Chihuahua, Coahuila, Nuevo León and the city of Tijuana.
Guerrero will host the largest concentration with 34 stations, while Oaxaca and Michoacán each receive two additional units, bringing their totals close to thirty. Mexico City already has about 100 stations, making its coverage comparable to major global hubs such as Tokyo and Los Angeles. The project, now in its third phase and funded by the federal Secretariat of Security and Protection, is slated for completion within the year. Data from the network are transmitted via fiber, UNAM's campus network and radio links to the Coordinación Nacional de Protección Civil and the Comisión Nacional del Agua within roughly 40 minutes of a tremor, and are displayed on a publicly available digital platform that maps intensity and acceleration minutes after an event.
