Mexico is a seismically active country Earthquakes with magnitudes larger than 7 0 happen, on average, every other year This fact requires a rapid and consistent response from the national monitoring agency, the Servicio Sismológico Nacional, SSN (Mexican National Seismological Service) For this purpose, in 2014, the SSN created a set of procedures for the daily operations and rapid response called “Protocolo de Respuesta Inmediata ante Sismos Amenazantes” (PRISA, protocol of immediate response to threatening earthquakes) This protocol has been triggered for 292 events with a magnitude larger than or equal to 5 0 that occurred between April 2014 and July 2020 Here we present the response of the SSN, based on this protocol, to three significant earthquakes: the 8 and 19 September 2017 events (Mw 8 2 and 7 1, respectively) and the 23 June 2020 (Mw 7 4) The first two quakes caused severe damage in southern and central Mexico, whereas the third occurred during the coronavirus disease 2019 pandemic and confinement in Mexico Having PRISA in place contributed to the efficient SSN response in the three events, even though some activities for the 2020 earthquake were performed remotely © Seismological Society of America

墨西哥国家地震局在正常和 COVID-19 大流行情况下对重大地震的响应

墨西哥是地震活跃的国家 平均每两年发生一次 7 0 级以上的地震 这个事实需要国家监测机构 Servicio Sismológico Nacional、SSN（墨西哥国家地震局）做出快速和一致的响应 为此目的2014 年，SSN 创建了一套日常操作和快速响应程序，称为“Protocolo de Respuesta Inmediata Inmediata ante Sismos Amenazantes”（PRISA，立即响应威胁地震的协议）该协议已针对 292 次震级事件触发大于或等于 5 0 发生在 2014 年 4 月和 2020 年 7 月之间 这里我们展示了 SSN 基于该协议对三个重大地震的响应：2017 年 9 月 8 日和 19 日事件（Mw 8 2 和 7 1，分别）和 2020 年 6 月 23 日（Mw 7 4）前两次地震在墨西哥南部和中部造成了严重破坏，而第三次地震发生在 2019 年冠状病毒病大流行和墨西哥的隔离期间 实施 PRISA 有助于有效的 SSN 响应这三个事件，尽管 2020 年地震的一些活动是远程进行的 © 美国地震学会
