Tsunami Evacuation Planning: Low-Cost Tool Maps Safe Routes for Coastal Residents

When an earthquake triggers a tsunami, coastal residents may have only minutes to reach safety. A new low-cost tool aims to help people plan successful evacuation routes, potentially saving lives in high-risk areas. The tool addresses a critical gap: even when evacuation routes are designated, they may not lead to safety if they are blocked, too long, or inaccessible for certain populations. By using the tool, communities can identify and improve routes, ensuring that residents can quickly reach high ground or designated shelters. This matters because tsunami preparedness often focuses on early warning systems, but the physical path to safety is equally vital. The tool's affordability makes it accessible to communities with limited budgets, which are often the most vulnerable. As sea levels rise and coastal populations grow, such planning tools will become increasingly important for disaster resilience. The takeaway: better route planning today can mean the difference between life and death when the next tsunami strikes.
