After the earthquake, why has it been raining and cloudy?

Due to the earthquake, the amount of dust in the air has greatly increased, and the heating effect of metal minerals in the geomagnetic crust makes the ground moisture evaporate rapidly, which means that there should be sultry weather before the earthquake. After the earthquake, the large-scale release of ground and underground energy accelerated the saturation of water vapor in the sky, and at the same time, the huge energy greatly increased the rising speed and height of this part of water vapor, which entered the high-altitude low-temperature area, and these water vapor and dust condensed into water or ice and dispersed, which was the reason for the rain after the earthquake.

Similarly, large-scale forest fires eventually end in heavy rain.

It sometimes rains before earthquakes, because the crustal movement will cause geothermal eruption. Yes, the local atmosphere will be heated to form an earthquake cloud, and it will rain when it meets the cold air above. This is the so-called rain before the earthquake. This is not a sufficient and necessary condition for an earthquake to occur.

Earthquakes also have a great impact on the natural landscape. The main consequences are faults and earthquake cracks on the ground. The surface faults of large earthquakes often extend from tens to hundreds of kilometers, and often have obvious vertical and horizontal offsets, which can reflect the characteristics of structural changes at the source (see the Houwei earthquake and the San Francisco earthquake). However, not all surface faults are directly related to the motion of the source, and may also be caused by the secondary influence of seismic waves. Especially in areas with thick surface sediments, ground fissures often appear at the edge of hillsides, banks of rivers and both sides of roads. This is often due to topographical factors. Without support on one side, the topsoil is loose and cracked due to shaking. The shaking of the earthquake makes the topsoil sink, and the shallow groundwater will rise to the surface along the ground fissure, forming the phenomenon of sand blasting and water inrush. A big earthquake will change the local topography, or uplift or sink. Urban and rural roads are cracked, rails are twisted and bridges are broken. In modern cities, water, electricity and communication are blocked due to the rupture of underground pipelines and the cutting of cables. The leakage of gases, toxic gases and radioactive substances will lead to secondary disasters such as fire, poisoning and radioactive pollution. In mountainous areas, earthquakes can also cause landslides and landslides, which often lead to the tragedy of burying villages and towns. The collapsed rocks blocked the river and formed an earthquake lake upstream.
