How to Help a Dolphin in Need.
One of the posters to this video stated the following:
quote:
If anyone its wondering why this happened, there was a 6.1 magnitude earthquake in Argentina South America on the same day. Earthquakes have a negative affect on their sonar causing them to get disoriented and breach themselves.
Doesnt restore it completely, but does put it on the right track. I'm no expert on dolphins, and if earthquakes do cause this disorientation effect in dolphins, than I've learned something new today.
I'd be a bit doubtful of the "Earthquake theory". At any given second, there are multiple earthquakes occurring all over the world. If an earthquake screwed up their sonar, there wouldn't be any coastal dolphins left in the water.
Here's what I'm talking about.
Magnitude
Average Annually
8 and higher
1 ¹
7 – 7.9
17 ²
6 – 6.9
134 ²
5 – 5.9
1319 ²
4 – 4.9
13,000
(estimated)
3 – 3.9
130,000
(estimated)
2 – 2.9
1,300,000
(estimated)
Sorry it didn't tabulate but there are about 1.5 million detectable quakes/year.
