We describe the regular pre-COVID mode of operations for the Canadian National Seismograph Network and the associated monitoring, alerting, and analysis for earthquakes in Canada;we describe how the current operational posture evolved and discuss the ways in which the posture was and was not suitable to respond to the challenges and constraints of the COVID-19 situation in Canada We find that many of the design and operation decisions that have been taken over the last several decades for earthquake monitoring in Canada, collectively driven largely by considerations of resilience and cost-effectiveness and further refined after the experience of the H1N1 pandemic, resulted in a system that continued to function effectively under lockdown conditions There were many earthquakes in Canada that required seismologist response during the lockdown, all of which were handled remotely without issue Specific challenges and lessons learned from the first few months of the pandemic are noted © Seismological Society of America

对加拿大地震监测和警报实践与 2020 年 COVID-19 经验的初始挑战的批判性评估

我们描述了加拿大国家地震台网在 COVID 之前的常规操作模式以及加拿大地震的相关监测、警报和分析；我们描述了当前的操作姿态是如何演变的，并讨论了该姿态存在和不存在的方式适合应对加拿大 COVID-19 形势的挑战和限制我们发现，过去几十年来加拿大为地震监测做出的许多设计和运营决策，主要是出于对弹性和成本的考虑- 在经历 H1N1 大流行之后的有效性和进一步完善，导致系统在锁定条件下继续有效运行加拿大发生了许多地震，需要地震学家在锁定期间做出反应，所有这些都是远程处理的，没有问题 注意到大流行最初几个月的具体挑战和经验教训 © 美国地震学会
