As a factor in luminescence phenomena and changes in geomagnetism, ground current, and electric fields, which are precursors to large-scale earthquakes, a mechanism has been proposed in which a free charge is generated in the crust when pressure is applied to the bedrock of the earth's crust, which appears on the ground surface and generates a ground surface charge, which also has an electrical impact on the sky. The presence of a large number of electrically charged aerosols and liquid microscopic water droplets floating in the air can also be seen by the rainbow in the desert. Thus, it is clear that a large charge on the earth's surface exerts a Coulomb force on charged particles suspended in the air and the stable motion path of airborne charged particles (i.e. microscopic water droplets coexisting with water vapor) is elucidated based on the principle of minimum mechanical energy, and the formation of seismic clouds is studied.As a result, it is difficult to solve the equations analytically, but the existence of two types of seismic clouds is mathematically proven as a singular solution to the equation, one far away and directly above the epicenter.
