"Explosion" behind the collapse of the Chinese dynasty

　Sudden climate change caused a volcanic eruption, especially with the existing social instability, causing the collapse of the Chinese dynasty-.

　AsianScientist -The rulers of each Chinese dynasty have been facing the invasion, rebellion, and other social anxiety for the past 2,000 years.However, an international team's research has shown one of the reasons for environmental stressers such as volcanic eruptions is one of the reasons for the collapse of the dynasty.The result was published in Communications Earth & EnvironMent.

　When a volcano erupts, it is assumed that destructive results are brought.Lava and volcanic ash spurt widely, like the ancient Rome Pompeii, and the town is buried.In the long term, climate patterns are susceptible to release from the volcano that covers the air.Solar is scattered, mainly for particles that are composed of sulfur dioxide gas, and water evaporation decreases, and rainfall is reduced.

　As the temperature drops sharply and drought becomes seen, the climate stressor causes agriculture and the livestock dies.However, it has been found that it is difficult to systematically explain the impact of volcanic activity on social collapse, because many disasters are one -time event and there is no evidence that can be applied through history.

　There are many dynasties in China's history.By examining the prosperous cycle of the 2,000 years of society, you will be able to gain knowledge about the impact of volcanic explosions on civilization.

　The International Research Team, led by researchers from Zhejiang University and Ireland Trinity College Dublin, uses accurate historical records and volcanic ventilation measurements from sulfur deposited in ice sheets to the environmental relationship between humans. investigated.

　The dynasty collapsed was 68, of which 62 of them had a volcanic eruption within 10 years before the collapse.In order to confirm that these observations were by chance, researchers tested in various time range.Comparing the collapse phenomenon randomly and compared with a computer simulation with the historical pattern.

　Surprisingly, the number of eruptions was considered in the initial time width, indicating that volcanic explosions and climate have repeatedly played a long -term role in the collapse of the Chinese dynasty.rice field.It has a complicated relationship, and some dynasties were able to withstand 10 years after eruption and collapse, but other dynasties collapsed very quickly after the eruption.

　The research team discovered that if the dynasty had already increased instability due to war, a small volcanic eruption would be a decisive or final trigger of collapse.On the other hand, if the volcanic explosion was large, it acted as a major cause of the fundamental collapse, even if the stressers that had already existed were small.

　The recent eruption is smaller than what the Chinese dynasty experienced in the past.But if there is a big explosion in the future, it will have a significant impact on some communities, especially those who are alienated and those who rely on agriculture.

　Researchers believe that the needs of future eruptions should emphasize the need for future eruptions, especially in areas with low climate resilience, especially in areas with low climate due to conflicts and other stressers.

"This study not only clarifies that it is inappropriate to explain the collapse in a monocular or environmental determination, but also the existing historical explanation that eliminates environmental factors is inappropriate.The authors point out."The climate shock triggered by volcanic is an important position in a series of factors that are frequently given in these events and should be integrated with them."
