Horses React to Approaching Storms
Farmers in earthquake-prone regions often watch their horses closely as a primitive but effective early warning system for impending trouble. Horses typically panic or bolt when earthquakes or storms approach. Ancient Greek historians like Pliny the Elder documented horses rearing up before quakes. These large animals possess extremely sensitive hooves that pick up subtle ground vibrations. Their ears also detect low-frequency sounds traveling through the air from distant disturbances.
