An earthquake of magnitude 6.8 occurred in Luding, Sichuan. Is hot and dry weather a precursor to an earthquake?

An earthquake of magnitude 6.8 occurred in Luding, Sichuan, and the hot and dry weather was not a precursor of the earthquake.

First of all, hot and dry weather is related to earthquakes. The high temperature in Sichuan and Chongqing has been a rumor since the summer. The temperature in many places exceeds 40 degrees Celsius, and the highest temperature reaches 44.4 degrees Celsius. Some people worry that the high temperatures in Sichuan and Chongqing may well indicate a major earthquake! But this is not the case, and the two are irrelevant.

Scientific research shows that before the earthquake? Abnormal fever? The reason is not the atmospheric temperature, but the formation temperature. A research report published in the Journal of Seismology pointed out that the temperature of rock strata may reach its peak before the earthquake. After the earthquake, the temperature dropped rapidly, with a difference of more than 3 degrees Celsius.

Taking Fengzhen, Inner Mongolia and Tangshan, Hebei as examples, at a depth of 0.8 meters, their magnitudes are 5.8 and 7.8, respectively, and the difference in ground temperature is obvious.

In fact, the main factors affecting high temperature are solar radiation and meteorological conditions. Even before the earthquake? Abnormal fever? But its main function is in the stratum, which has little influence on the temperature. So the high temperature in Sichuan and Chongqing before the earthquake was not? Signs of heat? .

Second, the precursors of earthquakes The most common precursors of earthquakes are the sharp changes in well water, such as color changes, temperature changes, fountain flow changes, and sudden changes in well water temperature.

In addition, there are abnormal habits of animals. Among them, animal abnormality is a common phenomenon of earthquake precursors, and its abnormal conditions and characteristics are different because of its different living habits, sensitivity and other factors.

For example, in the dead of winter, hundreds of poisonous snakes come out? Hole? Or? Suicide? Thousands of frogs and their young are hundreds of meters away from the epicenter. Because of the prominent macro-precursor characteristics of earthquakes, which are closely related to the daily life of ordinary people, it is relatively easy to find, and it is the most suitable method for group monitoring and prevention of large earthquakes.
