Tuvalu has a tiny area of land which is narrow and vulnerable; even the largest island is only 10 to 700 meters in width, so for the prevention of natural disasters the nation needs to develop measures in the light of these unusual local circumstances.
如前所述，由於吐瓦魯的土地狹小脆弱，最大的首島寬度也不過 10～700 公尺，在防治天然災害上需發展出因地制宜的作法。
