There will be drought before the earthquake

The weather was extremely hot. Before the earthquake, there were feelings of "extremely hot", "hot" and "uncomfortable". The temperature will be abnormally warmer than normal. Even if it rains heavily, it will be irritating. It will also feel abnormally warm in winter. Under these conditions, earthquakes may occur. For example, on March 8, 1966, before the Xingtai earthquake, the daily average temperature soared from minus 13℃ to above zero 11℃ within 7 days, a temperature increase of 24℃, which is really rare. Another example is that before an earthquake in Haicheng, there was an explosive increase in temperature. On February 3, 1975, between 8:00 and 10:00, the temperature rose by 12°C in 2 hours.

Strange winds and showers occur. Before an earthquake, strange winds will suddenly appear. The wind force is still very strong, and the wind direction keeps spinning. Wherever the strange wind passes, earthquakes will occur soon. It is such an amazing coincidence. On February 6, 1973, before a 7.9-magnitude earthquake occurred in Luting, Sichuan, within a few hours, there was heavy dust, chaotic wind direction, paper and dead leaves flying up and down, and the maximum wind speed was 14 meters/second.

Abnormal continuous or heavy rain, and extremely hot weather. On May 11, 1974, before a magnitude 7.1 earthquake occurred in Zhaotong, Yunnan, it rained continuously for 13 days, and the rainfall broke the historical record for the same period. There will be large-scale abnormal snowfall weather before earthquakes in winter. For example, on March 6, 1966, there was a rare heavy snowfall in the North China Plain in spring. As a result, the Xingtai earthquake occurred five days later.

The sky and the earth will shine. Before an earthquake, ground lights will appear in the lower atmosphere close to the ground. They will happen a few minutes before an earthquake. The color of the ground light is blue, white, or red. It often flashes at low altitudes on the horizon for a very short time. Before the Tangshan earthquake in July 1976, the train driver saw a blue light in the early morning hours. Soon after, the Tangshan earthquake occurred. When groundlight appears at night, there is a sudden flash of light in the dark night sky, and the mountain scenery in the distance can be seen. Before the 6.8-magnitude earthquake in Xingtai on March 8, 1966, and before the 6.7-magnitude earthquake in Pu'er, Yunnan, white lights were seen respectively. , red light.

The atmosphere is turbid. Before a major earthquake, it usually rains heavily. After the rain, the sky should be clean. However, before a major earthquake, the sky is turbid. It looks neither sand nor soil, nor smoke nor fog. The moon is pale and lightless. On February 5, 1966, a 6.5-magnitude earthquake occurred in Dongchuan, Yunnan. For four consecutive days, the sky was gray, the fog was thick, and the visibility was poor. Dongchuan had never seen a haze in history. 1-2 hours before the Haicheng earthquake, fog suddenly appeared, the sky was dark, and the sunlight could not be seen clearly. After the earthquake, the fog disappeared and the sky was clear and bright.

Atmospheric electrical interference is like the noise heard on the radio when a thunderstorm comes. This is the result of atmospheric electrical interference before an earthquake. The earth's atmosphere will also change before an earthquake, and people can smell a strange odor, which comes from cracks in the ground.
