How are earthquake clouds formed?

My friend, you must have read the article "Know the weather by looking at clouds", but did you know that you can also know earthquakes by looking at clouds?

You may not believe it. As early as17th century, ancient books in China recorded that "the sky is clear during the day or after sunset, but there are fine clouds like lines, which are very long and have warning signs". 1935 in Longde county, Ningxia, China, it was recorded that "the weather was fine, the blue sky was clear, and the dark clouds were like wisps, and Wan Ru was a long snake".

However, the international research on earthquake clouds is still in recent years, among which China and Japan are in the leading position. The study of seismic clouds in China began after the 1976 Tangshan earthquake, and there have been more than ten successful examples. In Japan, there are hundreds of successful examples of using earthquake clouds to predict earthquakes. Interestingly, it was not a seismologist but a politician who first proposed the name "earthquake cloud". He is the former mayor of Fukuoka, Japan. He once personally experienced the earthquake of magnitude 7 in Fukuoka, Japan, 1956, and saw a very strange cloud in the sky during the earthquake. As long as this kind of cloud appears in the future, there will always be earthquakes, so he called this kind of cloud "earthquake cloud".

So, what kind of clouds are earthquake clouds? The biggest feature of this cloud is "strange", which is obviously different from ordinary clouds.

The blue sky sometimes leaves traces of airplanes. The common banded seismic clouds are very similar to the wake of an airplane, but thicker and fuller. Generally, it means that the epicenter is perpendicular to the cloud direction.

In addition, there is a radial seismic cloud. Several banded clouds intersect at the same time, just like a fan rib without a sector spreading in the air. The intersection of clouds is perpendicular to the ground, which is the epicenter.

In addition, there is a striped earthquake cloud that looks like two rows of human ribs. Judging the epicenter according to this cloud is more complicated.

Earthquake clouds usually appear in the morning and evening. The longer the earthquake cloud lasts, the closer the corresponding epicenter is. The longer the earthquake cloud is, the closer it is to the earthquake. The more scary the color of the earthquake cloud looks, the stronger the corresponding earthquake intensity.

At present, there are different opinions about the cause of earthquake clouds. Although each has its own reasons, it cannot fully explain this phenomenon before the earthquake, so it is still a mystery. The earthquake itself is a very complicated process. Therefore, it is best to use comprehensive methods to predict earthquakes.

The cloud is the face of the earth. It can't lie. You can enjoy the clouds in the vast sky. Friend, would you like to witness the earthquake clouds and try to predict the earthquake?
