00:00Could a 1,000-foot mega-tsunami threaten America's coastline?
00:03The possibility sounds terrifying, but the real scientific warning is more complex.
00:08Along the Pacific Northwest, the Cascadia subduction zone
00:12could unleash a powerful earthquake and a destructive tsunami.
00:16Scientists warn that the disaster could also cause coastal land
00:20to suddenly sink by more than six feet.
00:22That means ocean water could reach farther inland,
00:25exposing more homes, roads, and infrastructure to flooding,
00:28and rising sea levels could make the consequences even worse in the future.
00:32The danger extends beyond the initial wave.
00:35Some coastal areas could remain more vulnerable to flooding long after the earthquake ends.
00:40Alaska and Hawaii face different tsunami hazards, including landslides and volcanic collapse,
00:46but experts cannot predict exactly when these events will happen,
00:50and the research does not forecast a 1,000-foot wave striking the United States.
00:55The real warning is clear.
00:57Understanding these hazards and preparing coastal communities could save lives.
