Robustness Analysis of the Regional and Interregional Components of the Weighted World Air Transportation Network

Figure 7

LCC of the North America-Caribbean component after its isolation from the network. The red dots are the remaining airports after attacks on the world air transportation network (a) strength attack, (b) weighted betweenness attack, and (c) weighted PageRank attack. The airports in the LCC isolated by the strength and weighted PageRank attacks are concentrated in the US and a small part of Canada. In contrast, airports are scattered in all the areas covered by the initial component after the weighted betweenness attack.
