Pond-Dwelling Animals Able to Sense Earthquakes?

During natural occurrences, many animals in  nature are often found having bizarre behavior before the disaster happens. With pond-dwelling animals, scientists have found out that animals may be able to sense chemical changes in the water when an earthquake will almost strike.

In 2009, a colony of toads abandoned their pond in L'Aquila, Italy days before an earthquake happened. Findings in the pond revealed that there were stressed rocks in the Earth's crust that released particles with a charge that reacts with the groundwater. Many animals that live near this groundwater are very sensitive to any changes, so they were able to sense the change before the stressed rocks create an earthquake.

Throughout history, replies, amphibians, and fish behave in unusual ways before earthquakes happen. With the use of continuing this research, scientists may be able to help save multiple lives to prevent when an earthquake will strike again.
