Tsunami Mitigation The area affected by the tsunami has been and continues to be highly damaged and polluted. Vast areas are still cluttered with debris, a natural landscape turned alien and bare. From all vantages are large collection piles of waste, struggling to bring order to the entropy. One might argue that we should never build in some of these places again, and in some instances, this is an educated suggestion. However, because these areas are damaged, they should be restored, and economically, this will largely mean private redevelopment. Future tsunami mitigation strategies should be implemented from the Japanese federal government, including strategies such as building back wetlands, backfilling a series of hills, creating parks and a series of forests. The purpose of many of these tactics is to create diversion routes for the water, push occupied land up, create mostly permeable surfaces, push buildings up off the ground, and slow incoming water down with vegetation and trees. The secondary tsunami mitigation strategy is effective evacuation routes and a functioning warning system. In some areas of Ishinomaki, the evacuation areas were not high enough, or proved to be unsafe as gasoline fires spread across debris. The redeveloped urban plan must take into account effective evacuation areas. The Japanese warning system has been highly successful given the current knowledge of the relationship between earthquakes and tsunamis. Though many evacuees knew of the dangers of a potential tsunami after the earthquake, there was no warning as to the severity of the tsunami, and this took many locals by surprise.
