Scientists have highlighted a significant tsunami threat to the French Riviera and other Mediterranean coastlines, with UNESCO stating a 100 percent chance of a wave at least one meter high within the next 30 years from 2022.
The Mediterranean Sea holds the second-highest number of recorded historical tsunamis after the Pacific, with around 20 incidents along the French Riviera from the 16th century to the early 2000s. Notable events include the 1979 Nice tsunami triggered by an underwater collapse, which killed eight people, and effects from the 2003 Boumerdès earthquake in Algeria that reached French shores in about 75 minutes.
