One suggested approach is to leave an uninhabited buffer zone extending shoreward from the water. In Hilo, Hawaii, after devastating tsunamis struck in 1946, 1960, and 1964, the vulnerable area near the city was declared a municipal park, where no structures were allowed to be built.
从前用于加强沿岸保护的方法可以为有助于防止未来伤害的重建提供路线图。一个潜在的方法是在近海留出一块无人缓冲区。夏威夷的希罗（Hilo）在经历了1946、1960和1964年海啸袭击后将薄弱区改建为市政公园，禁止营建任何建筑。
