Tsunamis are rare, but when they strike, they are the deadliest and most costly of natural hazards. With half of the world’s population expected to live in coastal areas more prone to tsunamis by 2030, investing in early warning systems and resilient infrastructure, will be vital to saving lives and economies, said the top UN official on disaster risks on Tuesday. Mami Mizutori, UN Special Representative for Disaster Risk Reduction laid out the benefit-cost ratio of building cities that will withstand increasingly frequent climate-related hazards, marking “World Tsunami Awareness Day”, designated by the UN General Assembly in 2015.
