Dogs can predict earthquakes because of their hearing

Dogs can hear the high-frequency sounds produced by friction and cracking in rocks before an earthquake occurs. Another evidence of this discovery is that dogs with flat ears are less responsive than dogs with pointed ears, because flat ears tend to block high-frequency sounds from entering the ears. Studies have also found that dogs with small heads are more responsive than dogs with large heads, just as elephants are sensitive to low frequencies and mice are sensitive to high frequencies. Why do dogs get upset when they hear the grinding and cracking sounds of rocks underground? Do they know what these sounds mean? Do they know danger is coming soon? Dogs don't know the answers to these questions. They just hear the sound of a screw crawling in the distance and want to avoid it.

Dogs can feel strange things depending on the sensitivity of their organs

Because animals’ bodies have extremely complex and sensitive sensing systems for environmental changes. For example, dogs’ sense of smell is more sensitive to certain gases than humans. It is 100 to 10,000 times stronger than humans and can detect certain odors released from the ground before an earthquake; a pair of cockroach tail whiskers are covered with 2,000 densely packed filamentous hairs, and the roots of the hairs form a highly sensitive miniature The "vibration sensor" can not only feel the intensity of vibration, but also where the pressure comes from.

Predicting earthquakes does not only rely on animal premonitions

Some animals do have abnormal reactions to earthquakes, but there is not necessarily a difference between "animal reaction" and "earthquake occurrence" There is a one-to-one correspondence. Because the current overall monitoring environment is much more complex than it was a few decades ago, electromagnetic interference, climate change, biological habits, etc. can also cause animals to "misjudge" earthquakes. Therefore, relying on animals to predict earthquakes is only a reference. Simply use Animal responses to "correspond" to earthquakes are not appropriate. And the characteristics of dogs also determine that it will not only react abnormally when earthquakes or natural disasters come, but dogs will react accordingly to any strange sounds, whether they are big or small, so it depends on the situation. Dogs' predictions of earthquakes are not guaranteed.

The relationship between earthquake magnitude and dogs’ reactions

The relationship between animal abnormalities before earthquakes and magnitude: As the earthquake magnitude increases, the types, quantities, distribution areas and responses of animal abnormalities There is a corresponding increase in intensity. Generally speaking, before an earthquake of magnitude 3 or so, individual animals have abnormal reactions. Before an earthquake of around magnitude 5, common animals will show obvious abnormalities in a certain area. Before a strong earthquake of around magnitude 7, a large number of strong abnormalities occurred in many animals in a large area. There is an obvious relationship between the distribution of abnormal animal reactions and intensity. The higher the intensity, the greater the abnormal response. Dogs with insufficient IQ will bark constantly or at people or the sky, and show restlessness, nervousness, and wanting to escape. Dogs with slightly higher IQs will behave aggressively towards their ownersIt barks, wants to escape from the house, and bites its owner to go outside. There are also unsettling behaviors such as the dog moaning incessantly, jumping back and forth, picking up the puppy and leaving the nest, going crazy, digging in the ground, etc.
