The news of another earthquake in Wenchuan broke the circle of friends, shock level 4.8. The source of the earthquake is 15 km deep, but it's not dangerous, but it's a little scary.
But all the friends who had pets at home found that before the earthquake, the dogs seemed very restless, jumped up and down and ran around the house. Some people said because they felt the earthquake, but it had not happened. How did they do that?
Wenchuan earthquake after 13 years.
The news of the Wenchuan earthquake was of interest to everyone, but before it occurred, the province of Taiwan had had an earthquake in the early morning, even 20 times within an hour.
However, it seems that the attention of the netizens is focused on Wenchuan because of the devastating earthquake in 2008.
Sichuan Department of Earthquakes reported that the 4.8 magnitude of the Wenchuan earthquake occurred 13 years ago.
Aftershocks are known to have developed in some order. The aftershock is a series of earthquakes after the main earthquake, because after the main earthquake, on the fault,
The distribution of stress will change and will result in a series of aftershocks during the adjustment process.
The pre-earthquake “unusual” behaviour of animals has, in fact, been clearly described for centuries, with unusual pre-earthquake agitations of animals, such as hibernation snakes, frogs jumping out of ponds, rat formations and dogs barking.
In the case of dogs, it and cattle, horses, sheep, pigs, chickens are known as “six animals”, and the earliest dogs, actually the grey wolves, are now the most loyal friends of humanity and the most rearing pets, usually for about 20 years.
Dogs are sensitive, especially in the hearing system, and dogs have a hearing response of up to 120,000 hertz, 16 times that of humans, and can hear 400 times as far as humans.
At the same time, the dog's ability to distinguish the sound position is twice that of humans, and it can distinguish 32 directions and even the number of vibrations per minute of the metronome.
It's well known that the dog has a very sensitive nose, but it actually has better ears and can tell very small or high frequency.
The ultrasound, the ability to distinguish between the sources. So, generally speaking, this characteristic of dogs is enough for earthquake warning.
Scientists have found that animals can sense earthquakes 20 hours early.
In 2013, a team of German scientists discovered that before the earthquake, the red ants, who had a very regular life, had become extremely active and even went out at night for food.
So between 2016 and 2017, the team of scientists chose a farm in Italy, where earthquakes were frequent, to experiment with cows, sheep and dogs.
Monitoring devices are installed on each of them, and data collection shows that these animals are able to detect the arrival of earthquakes in advance and, in the case of large earthquakes above level 6, at least 20 hours in advance. And even a small shock of about level 2 will be felt about an hour before the earthquake.
And what makes me even more curious is how animals feel about earthquakes. If dogs can hear very small ultrasounds, how do you know that 20 hours before the earthquake?
In addition to ultrasound, there was a special change before the earthquake, which was a special mineral released from plate motion, which formed an ion in the air, making it different.
Humans do not notice this, but dogs are extremely sensitive to the smell, and these ions will make it soar, which is the signal of disaster.
Final summary:
In fact, the most important thing to say about so many dogs' predictions of the earthquake is that the owners need to know enough about their habits, or even if they're going to be so excited, the owners of the dogs are wrong about it as a “recreational way”, which is not helpful.
The other point is that the abnormal behaviour of the dogs prior to the earthquake is not fear of the earthquake, but rather wants to draw the attention of the master in this way and to discover that they behave differently in peace, simply to convey a message. So you know enough about your dog?
