一项新的研究查明了3 700多条有地震风险的新西兰河流,其中450条大到足以引起重大洪灾。 A new study identifies over 3,700 New Zealand rivers at risk from earthquakes, with 450 large enough to cause major flooding.

坎特伯雷大学的艾琳·麦克尤恩(Erin McEwan)的一项新研究创建了世界第一个数据库,追踪地震如何破坏河流和防洪,确定3,700多条新西兰河流在断层断裂时面临风险,450多条大河足以引发大洪水。 A new study by University of Canterbury’s Erin McEwan has created the world’s first database tracking how earthquakes disrupt rivers and flood defenses, identifying over 3,700 New Zealand rivers at risk if fault lines rupture, with more than 450 large enough to cause major flooding. 该研究基于52个全球地震和新西兰的断层及洪水数据, 显示过去的地震已永久改变河水流量, 并破坏断岸, 造成持久的洪水灾害。 The research, based on 52 global quakes and New Zealand’s fault and flood data, shows past quakes have permanently altered river flows and damaged stopbanks, creating lasting flood hazards. 该模型在自然灾害委员会的支持下,帮助规划者模拟震后洪水,改善风险缓解,指导更安全的发展。 The model helps planners simulate post-quake flooding, improve risk mitigation, and guide safer development, supported by the Natural Hazards Commission.
