Cordons provide a useful, but challenging risk-management tool for protecting public safety in a post-earthquake environment. There is limited literature on the purpose, complexities, and societal implications of post-earthquake cordons. Using evidence primarily from the 2011 Christchurch earthquake, and observations from the 2009 L’Aquila earthquake, this exploratory study identifies and highlights the various avenues of consideration involved in cordon establishment. This study shows that a cordon brings about complex challenges, pertaining to housing, law, economy, social welfare, governance, civil liberties, and health. We find that cordons can support both short-term and long-term recovery processes. Three themes emerge: (1) the tensions between minimizing risk for public health and safety and constraining the rights of the public and private parties; (2) the roles, rights, and relationships between government and private sectors; and (3) the balancing of short-term benefits of cordons against longer term impacts to the wider post-earthquake community. This exploratory study of the challenges, complexities and consequences associated with cordons over short, medium, and long terms may inform cordon-related decisions and improve outcomes for communities following an earthquake.

震后警戒线及其影响

警戒线为在地震后环境中保护公共安全提供了一种有用但具有挑战性的风险管理工具。关于震后警戒线的目的、复杂性和社会影响的文献有限。这项探索性研究主要使用 2011 年基督城地震的证据和 2009 年拉奎拉地震的观测结果，确定并突出了建立警戒线所涉及的各种考虑途径。这项研究表明，警戒线带来了复杂的挑战，涉及住房、法律、经济、社会福利、治理、公民自由和健康。我们发现警戒线可以支持短期和长期的恢复过程。出现了三个主题：(1) 最大限度地降低公共健康和安全风险与限制公共和私人团体的权利之间的紧张关系；(2) 政府与私营部门之间的角色、权利和关系；(3) 平衡警戒线的短期利益与对更广泛的震后社区的长期影响。这项对短期、中期和长期与警戒线相关的挑战、复杂性和后果的探索性研究可能会为与警戒线相关的决策提供信息，并改善地震后社区的结果。
