Animals must have an extra sense, or else they must receive some specific signal, which people cannot pick up, when an earthquake is about to take place. I have never been a proponent for animal creulty, but if we could learn how to predict earthquakes by hooking up wires to the brain of a dog, I think I could deal with it. Earthquakes might give off a type of high-frequency sound wave, like a dog whistle, which only animals can hear. I think it would be worth the time, money, and yes, the animals, to find out what warns animals of earthquakes. It seems to me that if one were to chart the rock types in a region and their elasticity, then one would be able to see if an earthquake is about to occur.
Scientists are able to see how much stress is presently on a given area of rock.
They are also able to calculate the amount of stress a rock can handle before it breaks and rebounds back to its original position. With these two pieces of information, it seems logical that seismologists and geologists could predict when a given fault is about to give way. My next proposal for predicting quakes may seem very risky, or maybe even absurd, but I believe it might help improve our current situation. Earthquakes occur because of a releasing of stress or pressure on the rocks. Scientists have proven that much of the stress in subduction zones is due to the presence of water in the rock.
