What kind of phenomenon is the earthlight? Please, thank you

Before and after **, the blue light that appears in the sky is actually the light of the earth. When it is about to happen, people in the area or on the edge can see with the naked eye that the sky will appear in bands, columns, or flakes of light, and the color is mostly white and blue. This is scientifically called "ground light", and this phenomenon generally occurs on a larger scale.

Why is there a light on the ground? The cause of geolight is currently inconclusive in the scientific community, but most people believe that it is due to the pre-geomagnetic anomaly, which causes atmospheric particles to discharge and emit light. Specifically, when encountering a large **, cracks appear on the ground, there will be a huge shear force, the formation rock is quickly teased and cut, cracked, broken cavity cracks, in this process, the rock will produce a high degree of friction and sliding, the temperature rises rapidly, resulting in an electromagnetic effect, some charges will be brought to the surface of the formation along the cracks, and the more and more charges gather, the atmosphere will be ionized at low altitude, causing luminescence.

The duration of the ground light in the air is very short, usually a few seconds for the mountain cherry blossoms, and the long time can last for a few minutes. The distance between the ground light and the surface of the earth is not large, generally ranging from ten meters to tens of meters. Because the possibility of small ** emitting ground light is very small, so when you see ground light, it indicates that the big ** is likely to come soon, so we should make full use of this short time, take necessary prevention and avoidance measures, and if possible, organize relevant personnel to evacuate to a safe shelter in an orderly manner, and strive to minimize the loss of life and property.

It is the earth that emits a special kind of light, and it is particularly dazzling, which is also a signal, which must be carefully observed, and this signal can make the entire surface of the earth change.

Ground light can be regarded as a signal, because ground light is the light that appears in the sky above the area affected by the vibration when ** occurs. Most of the time when the ground light appears at the same time as **, and sometimes it also occurs before and after the earthquake. The duration of ground light varies from a few seconds to tens of seconds, and the size and brightness of light are not necessarily proportional to energy, magnitude or intensity, and its shapes include ribbon light, flash, columnar light, sheet light, etc.

Lasers are actually a special natural phenomenon. And the ground light is a signal, once such a light appears, it means that it is very likely to happen**, so we must pay attention.

This is a peculiar natural phenomenon, a phenomenon that will occur before **, this is a signal, and when it comes, it means that ** is coming.

Ground light is a phenomenon observed by the human eye when ** occurs. Ground light is indeed an early warning signal, because it can be judged by ground light.

Refers to a natural phenomenon, which is a natural phenomenon after **, the phenomenon that the sky will glow, which is indeed a signal that is prone to natural disasters.

Refers to a natural phenomenon. It's a kind of signal, because when this kind of thing is sent, the ** situation will happen.

Most of the ground light is related to **, usually before **. Bright lights will appear in the sky. This is a precursor to what is to come. Some are red, others are blue-white.

Now there are two theories about the cause of this phenomenon of earth light: 1The content of quartz in the earth rock layer is very large, and the phenomenon of ground light will be produced due to the dislocation of the crust before ** will produce a great extrusion of these quartz

In the ** area, there are often radioactive materials with oxygen as the main component, which are taken out of the ground"Shake"to the atmosphere. In particular, in areas containing more radioactive materials, in acidic rock distributions and near faults, the radon content in the atmosphere will increase significantly (as evidenced by the measured results), which will also increase the ionization of the atmosphere and increase the conductivity. If there is a natural electric field on the ground (which can be generated by the piezoelectric effect), a large-scale discharge into the air will occur, causing the ground light to flicker.

Large-area discharges and rays emitted during radon transformation have the potential to excite fluorescence and make fluorescent tubes shine. In fact, I think that the generation of ground light may be a combination of the above two reasons, because both of them are very easy to produce ground light. As for the fireball, this one has to do with the atmospheric electric field, but the theory of cause is more complicated, and I can't give you a detailed explanation of this question.

However, if you are more interested in these phenomena, you can also check it out here.

Trouble, thanks!

How are the auroras on Earth generated? And what is Herotto?

Light travels in a straight line in the same homogeneous medium, and when it is obliquely transmitted from one medium to another, the direction of propagation is deflected - the refraction of light; The law of light propagation when light hits the surface of an object and is reflected back into the original medium - the reflection of light.
