How Animals Know About An Earthquake Before Humans?

“No scientific study has proven that animals reliably predict natural disasters, but if your beagle starts losing it for no apparent reason, brace yourself.

There’s enough anecdotal evidence of creatures freaking out and even fleeing areas en masse before earthquakes to take unusual animal behavior seriously, as our gallery of dog-related tweets that followed today’s 5.9 earthquake in D.C. suggests.

But there’s nothing supernatural or sixth sense about it. Seismologists think animals sense an electrical signal generated by the movement of underground rocks before an earthquake. Or they might sense early but weak shocks that humans can’t feel. Even the U.S. Geological Survey concedes that animals likely perceive earthquakes sooner than humans:

Very few humans notice the smaller P wave that travels the fastest from the earthquake source and arrives before the larger S wave. But many animals with more keen senses are able to feel the P wave seconds before the S wave arrives.
