1,000-ft ‘mega-tsunami’ could wipe away large regions of US. When is it coming?

A new study by geoscientists at Virginia Tech, published in ‘Proceedings of the National Academy of Sciences’, estimates a 15 per cent chance of a magnitude 8.0 earthquake hitting the United States within the next 50 years. Such a quake could trigger a 1,000-feet-high ‘mega-tsunami’ and threaten millions of lives. Regions at risk include Alaska, Hawaii, and parts of the US West Coast if the quake occurs along the Cascadia Subduction Zone
