Stories have been told of animals being able to predict natural disasters, such as dogs acting strangely before an earthquake, or elephants in a panic before a landslide. Is it possible that animals can sense or predict occurrences in the Earth?
Many scientists are sceptical, and think that perhaps rather than being capable of prediction, animals may simply be using their existing senses more effectively than humans can, such as the sense of hearing. A human ear can hear sounds in the 20 hertz to 20,000 kilohertz range, while any sound outside this range is undetectable. Certain animals however, such as bats, dogs, or elephants, have hearing ranges well beyond this.
In the case of an earthquake; they start with the movement of tectonic plates far below the ground’s surface. This involves the movement of seismic waves, which produce infrasonic sound, which has a lower frequency than 20 hertz. A human won’t sense anything, but for our canine companions, alarm bells begin to ring. The dog does not know that an earthquake is on the way, but they do detect something unusual, and try to move away from the source. This has given humans the illusion that dogs and other animals can predict earthquakes and other such natural disasters.
