Infrasound, Elephants and Earthquake Detection

Posted by timothy on from the how-low-can-you-audibly-go dept.

mediareport writes "Science News offers a timely antidote to simplistic mumbo-jumbo about the "mythical power" of animal earthquake detection. Anyone intrigued by reports of possible tsunami-avoidance behavior in Sri Lankan wildlife will enjoy this detailed examination of the latest research into low-frequency sound. Elephant rumblings that produce Rayleigh waves are now under serious study for the first time, while others are designing "highly unusual" experiments to test infrasound sensitivity in humans."

    I'm sure there was lots of infra-whats-a-ma-gig going on, but regardless of those factors, what it comes down to is that animals just aren't as stupid as humans.

    When confronted with an unusual, confusing situation, they get the fuck out. Whether it was the vibrations, the noise, or the distant sea swell, doesn't matter, they got the fuck out.

    Humans who feel planet earth is one great big disney park in which they have the right, if not the obligation, to experience *all* the rides, wander down the quickly receding waterline to check it out.

    I suppose it could be valid to think of earth as a disney park, so long as you remember that a large number of the attractions are named "death". If you are too blind to notice that on your way to the shiney new thing..... well.. then I've got a darwin for you.

    Hmmm... I would put it down to fish generally not being particularly bright outside of their day-to-day survival instincts, and as they are generally spread out, not needing to respond to such major events as a tsunami for the species to go on. They'd stay in their usual habitat, and if that local habitat goes, then the inhabitants go with it. Occasionally they'd ride a current, especially if given no choice. If they get washed ashore, bad luck.

    What I'd be more interested in is if any, and if so how many, larger sea creatures were dumped ashore. (I believe there were whale beachings in the general vicinity within that general window, but AFAIK it's just coincidental).

    I'm no marine biologist, so anyone with facts that support or shoot down my ideas are quite welcome to do so.
