This summer, China encountered many rare crises of high temperature, drought, and power shortage, making “Earthquake and Drought Theory” once again a hot topic of discussion on Weibo.
Recently, rumors have been circulating on the Chinese internet that “there will be a major earthquake after the great drought,” and quoted Geng Qingguo, a Chinese geologist, who came up with the theory. He believes that there is a correlation between earthquakes and drought. While earthquakes are forming, the meteorological effects caused by earthquakes are expressed as a series of extreme values of climate and catastrophic weather.
According to statistics on these connections from 1956 to 1970, Geng Qingguo found that “the epicenter of large earthquakes of a 6 magnitude or higher usually occurs in dry areas for 1 to 3.5 years before the earthquake. The larger the dry zone, the longer the duration, the greater the magnitude of the earthquake.
According to “The Paper,” in the study of the “Earthquake and Drought Theory,” the probability of a major earthquake occurring within 3 years after a drought is as high as 84.8%, and only 15.2% of arid land had no major earthquakes within 3 years of the disaster.
Geng explained that: The direct cause of earthquakes is the concentrated release of internal pressure of the earth’s crust, although the stress release rate is very short, but the annealing time is very long. During the nurturing of earthquakes, huge amounts of energy are released that can cause anomalous changes in the lower atmosphere.
During the preparation of a major earthquake, due to the increase of geothermal heat, the ground will be dry and hot, which will greatly reduce the water vapor content in the air and reduce the humidity, so it is difficult for clouds to form. The absence of cloud cover, allows the sun to shine directly on the ground, further exacerbated the drought.
However, The Paper said that so far, “scientists have not detected any signals before an earthquake.”
After the related news was released, many netizens commented. The Vision Times has compiled some comments from Chinese netizens:
“I don’t know if there will be a major earthquake after the drought, but there was definitely a big flood.”
“The Haicheng earthquake, the only major earthquake in the world, was predicted by Geng Qingguo!” “Reliable.”
Recorded data show that, in 1972, Northern China suffered a severe drought that had not been seen in decades. A 7.3 magnitude earthquake occurred in Haicheng, Liaoning in 1975, and a magnitude 7.8 earthquake occurred in Tangshan in 1976.
In addition, in 2006, Sichuan and Chongqing suffered severe droughts, some areas suffered from an extreme drought that occurred only once in a century. Temperatures in some areas many times exceeded 40 C (104 F), even 44℃. This drought lasted until 2007. Then on May 12, 2008, the Wenchuan earthquake that shook the world occurred.
The weather forecast on August 28 for Sichuan, Chongqing, Guizhou, Hubei, Hunan, Jiangxi, Zhejiang, Fujian, Guangdong, Guangxi, Hainan, … was from 35 to 39 C (95 to 102.2 F).
“A major earthquake came after the great drought.” How did this saying come about? According to Sohu, this saying can be traced back to the spring and autumn period and the Warring States period. The novel “Guoyu” by Zuo Qiuming recorded an incident of the King Zhou Youwang Dynasty.
In the second year when King Zhou Youwang came to power, the water levels of the three famous rivers of the Western Zhou Dynasty – Jingshui, Weishui, and Luoshui, plummeted to the point of drying up. At that time, the Qishan earthquake occurred, which must be the first recorded earthquake of a 6 magnitude or higher in Chinese history. The earthquake caused great damage. The “Great History” (Shiji) by Sima Qian recorded that all three major rivers in Xizhou stopped flowing, and even landslides occurred in Qishan.
