Earthquake warning system covering portions of central and southern Mexico
A SASMEX receiver installed at the Museo Universum in Mexico City
The Mexican Seismic Alert System (Spanish: Sistema de Alerta Sísmica Mexicano or SASMEX) is the earthquake warning system covering portions of central and southern Mexico. It currently provides up to 60 seconds' warning of earthquakes to Mexico City, Acapulco, Chilpancingo, Morelia, Puebla City, Oaxaca City, Guadalajara, Colima and Toluca. SASMEX is administered by a non-profit civil association, Center for Seismic Instrumentation and Registry (Spanish: Centro de Instrumentación y Registro Sísmico, A. C. or CIRES).
The SASMEX sensor network serving Mexico City has been regarded as the first earthquake early warning system issuing alerts available to the public.[1]: 74 SASMEX supplies regular information of all kinds, including reports of earthquakes of all magnitudes, and drills, via Twitter, under the name AlertaSísmica SASMEX. All earthquakes are reported as #TenemosSismo (we have an earthquake); warnings of serious ones are delivered as #AlertaSismica (earthquake alert).[2]
