Whale beachings
what causes whales to beach themselves? A mass beaching of 300 whales just happened in NZ, and i found some information saying whale beachings are indicative of a major earthquake or The biggest cause of whale beachings that I know of is high powered navy sonar that is searching for submarines. High powered Navy sonar is so loud it can be heard by whales for a thousand miles. When it is close enough it hurts them badly. And they often beach because of it. Whales will beach themselves any time they think they are sick enough or have enough of a problem to harm other whales. Mass beachings happen when large numbers of whales get extremely upset about something, enough to make them think they have a problem with themselves. So whatever that would be, outside of navy sonar it is anyone's guess.
