Default Re: whale beachings, sonar, and earthquakes.

Nah, SONAR...

The US navy's new sonar, called Surtass LFA, carries 18 loudspeakers that generate 235 decibels each. In crude terms, that is equivalent to standing next to an Apollo moonrocket. At a range of 160 kilometres, the signal can still reach 160 decibels. That is 50 times louder than the US navy's official safety limit for human divers.
