...Gerardo Suárez; J. M. Espinosa‐Aranda; Armando Cuéllar; Gerardo Ibarrola; Armando García; Martín Zavala; Samuel Maldonado; Roberto Islas ABSTRACT The Mexican Seismic Alert System (SASMEX) initiated operations in 1993. It was the first to broadcast seismic early warnings to the general population...

...Armando Cuéllar; Gerardo Suárez; J. M. Espinosa‐Aranda Abstract A performance evaluation of the detection and classification algorithm for earthquake early warning 2 ( t S – t P ) was conducted to test its reliability and robustness. The Seismic Alert System of Mexico (SASMEX) has used...

.... They have been designed for low-impact damage due to adverse climate and lightning. All systems operate in an inert atmosphere to avoid corrosion failures and are solar energy–powered thanks to their low energy consumption ( Espinosa-Aranda and Rodriguez 2003 ). The SASMEX also aims to achieve the best...

... algorithms used by the Mexican seismic early warning system (Seismic Alert System of Mexico [SASMEX]). It was designed to alert earthquakes within the subducted Cocos plate. The t P + 3 algorithm was based on a training dataset of 76 accelerograms of 25 Mexican in‐slab earthquakes, with focal depths > 40...

The final section, “Engineering with Earthquakes,” focuses on the engineers behind the SASMEX system, exploring how they understand earthquakes, their engineering priorities, and their experiences in the field. While there is something...

... Mexicano [SASMEX]) was installed and in full operation by 1993, in order to provide earthquake warning within 60 s for portions of central and southern Mexico ( Aranda et al. , 1995 ). During the normal‐faulting M w  8.1 earthquake (Fig.  1 ), which struck off the Chiapas coast of southern Mexico...
