A devastating "mega-tsunami" might strike sections of the United States, especially along the Pacific Northwest, Alaska, and Hawaii, according to recent scientific studies. This caution is based on research by Virginia Tech scientists that was published in the Proceedings of the National Academy of Sciences, which shows that these areas have serious geological weaknesses.
Cascadia subduction zone The Cascadia Subduction Zone, a 600-mile fault line stretching from Northern California to British Columbia, is identified as a significant risk area. Researchers estimate a 15% chance of a magnitude 8.0 or higher earthquake occurring here within the next 50 years. Massive tsunamis might be triggered by such an event, which could force coastal land to collapse by up to 6.5 feet. According to the reports, the last great earthquake in this area happened in 1700, and another major seismic event is thought to be long overdue.

Alaska and Hawaii: Additional vulnerabilitiesDue to its unstable terrain, melting glaciers, and high seismic activity, Alaska is particularly vulnerable to landslides that could create mega-tsunamis. Similar hazards are present in Hawaii due to its volcanic terrain; historical records show that 1,000-foot waves have already been created by volcano eruptions. Different geological variables increase the likelihood of catastrophic tsunamis in different locations.
Historical data and potential impactThe Alaskan incident in Lituya Bay in 1958 is a sobering reminder of these risks. The largest tsunami ever recorded, reaching 1,720 feet, was caused by a major landslip. Even though this happened in a rural location, a comparable incident in a populated area might cause a catastrophic loss of infrastructure and human lives.
The Pacific Northwest might be severely damaged if a mega-tsunami were to occur. It is estimated that the destruction that it will cause, will take decades to recover.

Preparedness and mitigation effortsGiven these concerns, experts emphasise the importance of taking precautionary measures, such as developing comprehensive evacuation plans, fortifying infrastructure, and initiating public awareness campaigns about the dangers of tsunamis. Potential casualties and damage can be greatly decreased by funding early warning systems and community readiness.
It is imperative that governments and citizens in areas at risk prioritise readiness and resilience against the imminent threat of a mega-tsunami as the scientific community examines these concerns further.
