Usama Kadri, a mathematician at Cardiff University in the UK, has published new calculations in the open-access journal Heliyon demonstrating the possibility of neutralizing tsunamis with underwater sound waves. While actually implementing such a scheme would be enormously expensive and an enormous technical challenge, there aren't a whole lot of other tsunami defenses that don't basically just reduce to "getting the fuck to high ground before the wave hits." So, it's pretty novel.The sound waves in question are more properly known as acoustic gravity waves (AGWs): vast underwater waves that travel at the speed of sound and are generated naturally by earthquakes and other geological events.
