地震前兆（earthquake precursor） Many animal certain organs it can feel very sensitive than humans know ahead of some disaster events, such as jellyfish in the sea can forecast storm, the mouse can advance to avoid mine collapse or harmful gas invasion and etc.. As for what plays a major role in vision, hearing, touch, vibration, and balance organs, which may serve as an auxiliary judgment, may be different for different animals. The physical and chemical changes associated with earthquakes (vibrations, electricity, magnetism, weather, water radon anomalies, etc.) often cause some sensory organs in animals to be stimulated and react abnormally. If the gravity of a region varies, some animals may sense it through its balance organs; a vibration abnormality that may be sensed by the hearing organs of certain animals. Before the earthquake in the underground rock has been slow daily activities, showing a peristaltic state, and also has strong friction between the fault plane, so people think that in the low frequency acoustic wave friction on the fault plane will produce a few times per second to more than 10 times, less than the hearing can feel. One can only sense more than 20 sound waves per second, whereas animals do not. Those who feel very sensitive animal, the feeling to the sound, will be frightened and agitated, resulting in winter snakes from the hole, the surface of the water, the cattle jumping ring, see deep-water fish or strange fish in shallow water. The abnormal phenomenon of general turmoil. There are many kinds of animals, such as big animals, poultry, cave animals, hibernating animals, fish and so on. Animal response before earthquake and abnormal performance of animals: Cattle, horses, donkeys and mules: panic, not into the stable [ji], not eating, connected, barking rampage gang fights and break the reins of escape, stomp, dig, suddenly walk away. Pig: no direction, without food, yelling rampage, arch ring, the ring of flight. Sheep: no direction, withou
