A recent study, published in the Journal of Zoology has found that Toads are able to predict an earthquake. It was found that a colony of toads left their mating site three days before an earthquake occurred in Italy. Their ability to predict an earthquake is still under question, however it is believed that they may be able to detect seismic waves directly, or the anomalies in the Earth’s magnetic field caused by a quake. Before a quake a lot of charged particles are released in the atmosphere Toads and amphibians are very sensitive to changes in environmental chemistry. These gases and charged particles could have been detected by the toads.
