This year, not only have rare high temperatures occurred in many places in southern my country, but also sustained high temperatures have occurred in many countries around the world. At the same time, some alarmist statements are also circulating on the Internet, such as summers will get hotter and hotter in the future. The most outrageous thing is that "a major drought will be followed by a major earthquake" is widely circulated on the Internet. And it has been recognized by some netizens, who believe that it is better to believe that it exists than to believe that it does not exist. The credibility of the rumors left by the ancestors is still relatively high.

If you search for "drought earthquake theory" on the Internet, you can find that Baidu Encyclopedia provides an entry, and the proposer also has the title of earthquake scientist. The Wenchuan earthquake in Sichuan proved the earthquake scientist Geng Qingguo drought earthquake theory. Therefore, the editor checked relevant information on the Internet to see if there was a drought before the Wenchuan earthquake on May 12, 2008. In fact, a severe drought happened in the surrounding area one year before the Wenchuan earthquake. As early as 2011, the then deputy director of the Earthquake Forecasting Department of the China Seismological Network Center said in an interview with the media that using drought and climate anomalies to predict earthquakes has a high false alarm rate and is difficult to use for pre-earthquake predictions.

In addition to the "drought earthquake theory", there are also many precursors to earthquakes spread among the people, such as " earthquake cloud " and "haze predicts earthquakes". However, experts said that first of all, there must be sufficient facts to prove the existence of the intrinsic correlation between the two, and secondly, reasonable physical theories must be found to demonstrate the correlation between the two. Only if these two conditions are met can it be proven that these phenomena are indeed related to earthquakes. The following is the hot discussion among netizens on "A major drought must be followed by a major earthquake":

@ProfSu: Regardless of whether it is accurate or not, it is conceivable that after a drought, groundwater will decrease and the bearing capacity of surface soil and rock layers will decrease. , once an earthquake occurs, it will be catastrophic.

@EARTHhE: This is because the earth’s orbit has been close to the sun for a long time, which is caused by the sun’s heat radiation. According to my logical definition of the universe, the earth’s rotation speed has slowed down this year. The logical definition of the earth is that of the sun. Thermal radiation has increased by a vest radiation. According to the cooling reaction of the Arctic and Antarctic, the evaporation of seawater in the Pacific and Atlantic Ocean has not changed yet, and there is an illusion of drought and cold this winter!

@fallb1R2A: Yunnan experienced a severe drought for three years from 2008 to 2010, and now more than 10 years have passed.

@Kishibe Shinakiri: It is obvious that a severe drought is more likely to occur before a major earthquake, but a major earthquake is more likely to occur after a major drought. Let's figure out the logical relationship. Specifically, 1 out of 10 major droughts was followed by a major earthquake, but 8 out of 10 major droughts were preceded by major earthquakes. Don't create panic for nothing.

@星野BJiHR: I have read a book about the causes of geological earthquakes before. It did not mention information about severe droughts and earthquakes, but it proposed that water will play a certain role in geological faults. It also proposed that building reservoirs will not only increase The underground water content of nearby strata may also cause earthquakes due to changes in the strata due to the weight of water in the reservoir. In turn, the drying up of lakes and reservoirs caused by severe droughts and the decrease in groundwater levels may also affect the formation and cause earthquakes. However, this reason may be complicated and difficult to predict with current technology.

Generally speaking, there is no scientific basis for saying that a severe drought will be followed by a major earthquake. At least so far, scientists have not detected any signals that seem to be certain before a major earthquake occurs.
