What was done to restore damages caused by tsunamis?
Many people, including the government, donated huge sums of money, food, clothing to victims of tsunamis, and to rebuild houses and infrastructure, restore the scenery etc. Many people also volunteered to do these activities. That also depends on what was destroyed. Some damages might also include fishing boats, historical sites and also flooding, which either needed the people to pump the water out manually or using drainage systems, which proably could have clooged, or wait for it to dry/evaporate.
