Recent headlines warn of the potential for mega-tsunamis—massive waves triggered by landslides or volcanic collapses rather than earthquakes. While the idea of a 1,000-foot wave hitting the U.S. coast sounds terrifying, experts emphasize these scenarios are extremely rare and often theoretical.

Scientists continue to study past geological events, like asteroid impacts and volcanic collapses, to better understand future risks. Some focus has returned to the Cumbre Vieja volcano in the Canary Islands, which, if it were to collapse, could send a tsunami across the Atlantic. However, many researchers say this scenario is unlikely, noting the volcano has erupted without such effects in the past.

The U.S. regions with the highest tsunami risk—Alaska, Hawaii, and the West Coast—are closely monitored with early-warning systems and improved disaster preparedness.

The good news? Scientists are actively researching, monitoring, and improving our understanding and response to natural threats—keeping communities safer through knowledge and early action.
