Hawke's Bay Tsunami Evacuation Blue Zone

Data last updated: 18 August 2026.Now supersedes and replaces all previous tsunami evacuation zones. Filter status field to 'current' to see newzone. The map shows the CDEM-recommended evacuation zone in the event of a ‘Long’ (1 minute or longer) or ‘Strong’ (difficulty standing up) for the Hawke’s Bay Region. The evacuation zone, shown in blue, is the area that people should leave immediately following a long or strong earthquake. People should not wait for any alerts or announcements and should evacuate on foot wherever possible. The use of a single blue zone is in accordance with the latest national guidelines and best practices. The extent of the zone is based on computer modelling described in the GNS/EQC report available at:https://www.hbemergency.govt.nz/assets/Documents/Hazard-Reference-Documents/4616-AM1403-Hawkes-BayTsunami-Inundation-by-Attenuation-Rule.pdf Other evacuation zones are based on better quality data (e.g. Level 3 LiDAR data), better computer models and processing power. This map came into effect and made publicly available on October 10, 2024.数据最后更新时间：2026年8月18日。本数据集现已取代所有既往海啸疏散区划。将状态字段筛选为「current（当前）」即可查看最新区划。本地图展示了霍克斯湾（Hawke’s Bay）地区针对「长时地震」（持续1分钟及以上）或「强震」（站立困难）场景下，由民防与应急管理局（Civil Defence and Emergency Management, CDEM）推荐的应急疏散区划。图中以蓝色标注的疏散区划为民众在遭遇长时或强震后需立即撤离的区域。民众无需等待任何警报或通知，应尽可能徒步完成撤离。本次采用单一蓝色区划的设置符合新西兰最新国家指南与行业最佳实践标准。该疏散区划的范围基于新西兰地质与核科学研究所（GNS）/新西兰地震委员会（EQC）报告中所述的计算机模拟结果，报告详情可查阅：https://www.hbemergency.govt.nz/assets/Documents/Hazard-Reference-Documents/4616-AM1403-Hawkes-BayTsunami-Inundation-by-Attenuation-Rule.pdf。其余疏散区划则基于更高质量的数据（例如三级激光雷达（LiDAR）数据）、更先进的计算机模型与计算算力。本地图于2024年10月10日正式生效并对外发布。
