Why was the weather abnormal before the earthquake?

Before the earthquake, sometimes the weather was dry, but well water (groundwater) soared and even overflowed the surface. Well water should have gradually increased in rainy season, but it dropped sharply or even dried up. In some places, there is no water source, but a lot of water gushes out of the ground and so on. The reason is that in the process of earthquake preparation, due to the role of geostress, the geostress is constantly increasing, especially near the epicenter; Crustal activity has intensified. The water level in the extrusion zone will gradually rise; Under the action of tensile stress, the water level in the tensile area will gradually decrease. In particular, the local area of the earth's crust is damaged, deformed or accelerated under the action of geostress, and the water between the upper and lower layers caused by the destruction of rock strata will make the water level rise and fall sharply, which is the basis for using groundwater to predict earthquakes.
