Default Re: whale beachings, sonar, and earthquakes.

Nah, SONAR...

Quote:
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.
