Toad's Predict Earthquakes

It is a well known fact that when miners are mining, if rodents begin to flee the area it is time to follow. The rats have natural instincts and serve as a warning signal that something bad is about to happen. This apparently is true for toads as well. Five days prior to an earthquake that struck L'Aquila, Italy 96 percent of male toads in a breeding area fled the scene. Due to the fact Maury running around with paternity tests was not witnessed, a different explanation would have to be found. It is believed that the toad's activity acted parallel to disruptions in the ionosphere and thus is what triggered the toad's reaction. The article points out that the toads respond to other natural changes, such as a full moon or a release of radon gas. However, none of these events were going on prior to the earthquake, and therefore could not account for the panic.

The common toad (Bufo bufo) may actually prove to be a warning system for earthquakes.
