Tidbit #26 - April 23, 2011

Bark! Bark! Bark! Bark! Bark! Bark! Isn't it annoying when your dog barks all night? You're trying to get to sleep and its insistent howling and barking gets so aggravating! But then, just a few hors later, the Earth starts shaking! You're too late to realize that your dog was trying to warn you, and too scared to wonder how it was able to try to warn you!

Question: How do dogs sense an earthquake hours before it happens?


Answer: There's a whole website that I found out about based solely on questions just like this. It's called onearthquakes.com, and I found a forum question that asked exactly what we're looking for here. If you don't want to read that whole article, I fished around in the comments and found the answer, no wall of text or summary needed:

"Animals are sensitive to the change in the Earth's magnetic field just before the earthquake." (Re: onearthquakes.com)
