The occurrence of a large earthquake near or under a body of water is what alerts the computers to alert people. This makes sense because most (I’ve seen numbers from 80% to 95%) measurable tsunami are caused by earthquakes.Thu, 14 Feb 2019 20:40:00 +0100forbes-bf5450081321fed00aecef85d526e07d20190214204000
