What is the formation principle of earthquake clouds? Can you really predict earthquakes?

The empirical prediction of earthquakes is nothing more than the following aspects: geomagnetism, geoelectricity, ground temperature and water level.

The change of geoelectricity and water level seems to have little to do with the "clouds" in the sky and can be ruled out. I have carefully considered the ground temperature. According to the characteristic time formula of continental heat transfer: L=sqrt(kt), that is, the time required for the propagation distance of temperature change l is the square of l divided by k, and the order of k is 1mm2/s, assuming that when an earthquake is about to occur, there will be a great temperature change at the focal position (assuming that the ground is shallow 10km), then this change will be transmitted to the ground.

Geomagnetism is not my strong suit. I don't know if its change has a certain influence on the accumulation of substances in the atmosphere, but usually the geomagnetic change is after the earthquake. Welcome geomagnetic strongman to add.

The research of earthquake prediction is in the primary stage of data accumulation. After all, we can't see or touch anything underground. We should look at earthquake prediction from a scientific point of view, rather than credulous rumors such as "earthquake clouds".
