Mathematicians devise way of calculating tsunami size

Mathematicians have devised a way of calculating the size of a tsunami and its destructive force well in advance of it making landfall by measuring fast-moving underwater sound waves, opening up the possibility of a real-time early warning system. The sound waves, known as acoustic gravity waves (AGWs), are naturally occurring and can be generated in the deep ocean after tsunami trigger events, such as underwater earthquakes. They can travel over 10 times faster than tsunamis and spread out in all directions,…
