Experts warn that a massive “mega tsunami” could strike parts of the U.S., especially Northern California, Oregon, Washington, Alaska, and Hawaii, due to seismic threats like the Cascadia Subduction Zone. A Virginia Tech study found that a major quake could sink coastal land by up to 6.5 feet, heightening flood risks. With a 15% chance of an 8.0+ quake in the next 50 years, combined with rising seas, coastal towns could be overwhelmed. Alaska faces landslide risks from melting glaciers, while Hawaii is threatened by collapsing volcanoes. Experts urge residents to know evacuation routes and prepare emergency plans—it’s not if, but when.
