How long does the earthquake cloud appear? Will there really be an earthquake after the earthquake cloud?

I can't. Earthquake cloud is a kind of cloud that is misinformed to predict earthquakes in advance. At present, there is no accurate definition, and meteorological or geological majors do not recognize it. It is mainly circulated in China and Japanese folk. Chinese and foreign scientific circles, seismological bureaus and meteorological bureaus have repeatedly refuted this rumor, stressing that there is no effective evidence to prove that clouds can be used to predict earthquakes.

Due to the lack of the most basic definition of seismic clouds, it is difficult to generalize their characteristics as long as the "weird-looking" clouds are classified as seismic clouds. Many people think that all kinds of seismic clouds are mostly cumulus clouds or stratocumulus clouds, because these two kinds of clouds are easy to form weird shapes such as mesh, wave (rib), flocculent, transparent, radial and pod. In addition, it sometimes appears in the evening or early morning, stained with the color of sunset or sunrise, which makes people suspect that there is a vision in the sky.

However, altocumulus and stratocumulus, including other clouds suspected to be earthquake clouds, all have their corresponding genera and species in the scientific classification of clouds, and their causes have scientific explanations, so they cannot be used to predict earthquakes.

Extended data:

The theory of seismic cloud has never been accepted by the mainstream scientific community, and professionals in geology or meteorology have euphemistically or directly refuted it. It is neither a meteorological academic term nor a geological academic term. ?

Meteorologists believe that it is not uncommon for so-called clouds with different shapes to be related to high-altitude airflow activities; Meteorological stations around the world have never monitored the systematic warming of the surface temperature before the earthquake. Most of the pictures of "earthquake clouds" circulating in the market are high-level cumulus clouds or cirrostratus.

Geologists say that the change of geomagnetic field is not easy, and there is no theoretical support for the influence of electromagnetic field on cloud distribution. In other words, if earthquakes can be predicted by observing clouds, why can't people directly monitor the abnormal activities of the geomagnetic field? The so-called successful cases of earthquake cloud prediction are mostly the occurrence of earthquake clouds in one city, and a few days later, an earthquake occurred in another city thousands of kilometers away.

Zheng Guoguang, former director of China Meteorological Bureau and now director of China Seismological Bureau, pointed out in an exclusive interview with Wu Xiaoli, the host of Phoenix Satellite TV, that there is no scientific identification method for earthquake clouds. Earthquake is a three-dimensional geographical phenomenon. At present, 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.
