Scientists used AI to complete the US flood map, and the result is a startling gap: More than 11 million people and 4.1 million buildings may sit in flood zones that official records never counted

A gap in U.S. flood mapping systems, caused by outdated traditional methods, leaves millions of homeowners unaware of their true flood risk. Researchers used AI to create more accurate maps, revealing 11 million people and 4.1 million buildings in previously unrecognized flood-prone areas. This discovery has significant implications for the property market, insurance, and urban planning.
