SEAQUAKES LOUDER THAN NUCLEAR EXPLOSIONS
On page 36 of his book on sound imaging in the ocean, German underwater acoustic Professor Peter Willie, the former head of NATO's Undersea Research Center, displays three similar sonograms and compares the noise generated by undersea earthquakes and volcanic explosions with that of submarine nuclear explosions of several thousand tons of TNT-equivalent (ref #1). Professor Willie says earthquake sounds are the loudest underwater sounds ever produced. He also cautions that we should be aware of the underwater rumbling of "about 7,000 outstanding, dramatic geodynamic earthquake events per year worldwide, each of a thousand tons of TNT-equivalent and more." He ought to know because it's his job to determine the acoustic differences between underwater nuclear explosions and natural catastrophic events such as earthquakes. Professor Willie also expresses a belief that evolution has somehow intervened to protect whales fro...
