Today's earthquake cannot be accurately predicted. Which dynasty had the most earthquakes in history?

In the history of China, the Ming Dynasty was the most frequent period of natural disasters, which experienced more than 65,438+0,000 earthquakes and floods. According to scientific statistics, there were159 earthquakes in Ming dynasty in February16. Although there was an earthquake in the early Ming Dynasty, the harm was generally not great. For example, in the eleventh year of Hongwu, that is, 1378, Ningxia earthquake, the northeast wall collapsed "three feet and five feet", in the thirteenth year of orthodoxy, "the female wall fell 19 feet", 1448, and an earthquake occurred in Yulin, Yan 'an in September, and the wall fell 100 feet. The magnitude of these earthquakes is basically not high, and the impact on ordinary people is not too great, causing no casualties. By the middle and late Ming dynasty, the magnitude of the earthquake was getting bigger and bigger. In March of Zheng De's fourth year, a landslide occurred in Dajiayu, Shandong Province due to the earthquake. In April of Jiajing five years, the earthquake in Annan, Guizhou Province also caused landslides and destroyed houses.

Among them, in the thirty-fourth year of Jiajing, that is, 1556, the earthquake of magnitude 8 in Huaxian County was the most tragic. The earthquake * * * caused more than 830,000 deaths, which should be the record of the largest number of earthquake deaths in the world. The earthquake occurred in the middle of the night, covering more than half of China, 10 provinces and more than 200 counties, and it was felt. The building was immediately destroyed and there were cracks everywhere, including fish and boards. Weinan county, which is closer, has sunk more than ten feet. At that time, Huashan and Zhong Nanshan were ringing, so the Yellow River water was clarified for several days. The reason why the death toll from the Guanzhong earthquake exceeded the world record is that the earthquake triggered a flood, and after the flood, a large area of plague appeared in the disaster area.

According to modern seismologists, although there are some differences in the stages of earthquake activity in China, there is a general similarity in the description of the stage characteristics of earthquakes in the Ming Dynasty, that is, the middle and late Ming Dynasty is a period of high incidence of historical earthquake activity in China, while the early Ming Dynasty is a relatively quiet period of earthquake activity.

The average probability of earthquakes in the middle and late Ming Dynasty is above 350%, which is a fairly high index. It is equivalent to more than three earthquakes every year. Especially in the late Ming Dynasty, the earthquake frequency was the highest, with 343 earthquakes in just 50 years. The average probability reaches an astonishing 686%, which is equivalent to nearly 7 earthquakes every year.
