The Cascadia subduction zone, a major fault line along the U.S. West Coast, poses a deadly tsunami threat as researchers reveal the potential for a massive earthquake causing rapid land sinking and colossal waves.
With a 15% chance of a magnitude 8.0 or greater quake in 50 years, the resultant mega-tsunami could reach hundreds of feet and obliterate entire towns. Scientists warn that rising sea levels will exacerbate the flooding.
In addition to the mainland threat, Alaska and Hawaii face distinct tsunami risks from glacier melting and volcanic activity, making this a multifaceted danger for the Pacific region.
