Do earthquake clouds exist?

Today, Xi 'an's clouds are special and beautiful, but they are shaped like radioactive stripes. According to the data, they are earthquake clouds. Some netizens said that this indicates the Sichuan earthquake.

Rumors:

Clouds in the sky have nothing to do with earthquakes.

The word "earthquake cloud" is widely circulated on the Internet. Is there an "earthquake cloud"?

Please refer to Baidu Encyclopedia. "Earthquake cloud is a kind of misinformed cloud, which can predict earthquakes in advance. At present, there is no accurate definition, and meteorological or geological majors do not recognize it. Mainly circulated in China and Japan. Chinese and foreign scientific circles, seismological bureaus and meteorological bureaus have repeatedly refuted this rumor, stressing that there is no effective evidence that clouds can be used to predict earthquakes.

Meteorologists believe that from the professional point of view of meteorological observation, the photos of various seismic clouds given on the Internet can be classified into the following typical clouds, namely, semi-transparent clouds of altocumulus, flocculent cumulus, cirrocumulus and residual aircraft wake. These so-called earthquake clouds have nothing to do with earthquakes. ?

The description of the formation mechanism of seismic clouds such as the transformation of geothermal energy into clouds, the change of geomagnetic field and the luminescence of particles on the Internet cannot be established from the perspective of weather dynamics, cloud physics, evolutionary mechanics, thermodynamics and other related sciences. Geophysicists have never observed the change of magnetocaloric light when "earthquake clouds" appear, so the analysis of the mechanism of earthquake clouds is not in line with scientific principles.

The ever-changing clouds in the sky show the masterpieces of nature. The meteorological department recorded many beautiful and strange clouds in long-term meteorological observation. The formation and change of each kind of cloud has a stable corresponding relationship with the evolution of a certain weather. However, there are not enough facts to prove that there is an inherent correlation between earthquakes and weather, and there is no evidence that earthquakes can be predicted by satellite cloud images. Dr Li Ting, a meteorologist, thinks that "earthquake cloud is a pseudo-scientific concept". All the clouds called earthquake clouds have corresponding types in the classification of clouds, and most of them are concentrated in altocumulus clouds or stratocumulus clouds, because they are easy to form "weird-looking" shapes such as waves, flocs, light transmission and radiation. The so-called "earthquake cloud" is the general cloud in meteorological observation.

The so-called "earthquake cloud experts" use earthquake clouds to predict earthquakes, which often occur in hundreds to thousands of kilometers, which seems to be "accurate". We know this is actually a misunderstanding. On average, there are more than 5 million earthquakes in the world every year, which means there are tens of thousands of earthquakes every day. Thousands of destructive earthquakes of magnitude 5 or above occur every year in the world, almost two or three times a day on average. In other words, anyone who casually says "there will be an earthquake of magnitude 5 or above in the world today" will win and lose, not to mention that "earthquake cloud experts" have relaxed the time scale for predicting earthquakes to less than one month, so it is easy to predict the "second strike" of earthquakes.

It is necessary to expose these earthquake prediction methods. We should realize that the so-called "earthquake clouds" do not exist, and those "beautiful clouds" have nothing to do with earthquakes. "Earthquake Cloud" is a pseudo-scientific rumor.
