It may be weird but the fact is, all the animals and small creatures on earth can predict earthquake. From worm to a dog, all of them can forecast these changes. It is also said that some creatures have the ability to detect earthquake before a week. Quakes occur by disturbance in earth crust that cause change in groundwater. Animals and ground creature are highly sensitive to these changes and that’s how they know about it before us. Isn’t it odd yet amazing? However, some scientists completely deny this theory because of no solid proof or evidence found behind this.
