Mexico’s City seismic alert system, created to warn inhabitants about earthquakes in time enough for evacuation onto the street, failed twice over the weekend, once due to human error and the other due to technological malfunction.

Following a 5.7 magnitude earthquake on he evening of Friday, March 19, the alarm system let out an incorrect warning announcing a drill rather than an actual physical seismic event.

The other warning went off Saturday , March 20, at 8:16 a.m., leading to the evacuation of thousands of citizens from their homes, and was blamed on “old infrastructure” due to certain areas not having yet been connected to the country’s new digital system.

Mexico City Mayor Claudia Sheinbaum requested the resignation of two officials who were designated in charge of issuing the false alerts.
