In this research, the effect of local exogenous shocks on seaports and maritime networks is assessed throughout three case-studies. The Hanshin-Awaji earthquake, the 9/11 World Trade Center attack and hurricane Katrina triggered a shock on Kobe, New York and New Orleans respectively and led to temporary port failures. A global database on vessel movements is computed to gauge the intensity, duration and scope of these shocks with descriptive statistics. Port-centered analyses of the disrupted ports and their geographic as well as topological neighbors are conducted to assess the resilience of local port systems using traffic volumes, distances, and graph-theoretical methods at various time scales, from daily to yearly evolutions. Main results demonstrate certain similarities between the three cases given the importance of traffic specialization and of the spatial range of disruption.

空间网络的破坏：影响港口和运输方式的重大冲击的比较研究

在这项研究中，通过三个案例研究评估了局部外来冲击对港口和海事网络的影响。阪神-淡路地震，9/11世界贸易中心袭击和卡特里娜飓风分别对科比，纽约和新奥尔良造成了震荡，并导致临时港口倒塌。计算了一个全球船舶运动数据库，以描述性统计数据衡量这些冲击的强度，持续时间和范围。进行以中断为中心的端口及其地理和拓扑邻居的以端口为中心的分析，以使用流量，距离和图论方法，在从每日到每年的演变过程中的各个时间范围内，评估本地港口系统的弹性。
