The Birth of Cheonchi: How has the Baekdusan volcano shaped this land over the past hundred years?
In Mount Paektu on the border between North Korea and China, whenever this volcano is mentioned, people will be reminded of its "Millennium Eruption" in 946. This powerful volcanic eruption is not only one of the most powerful volcanic events on record, but it also continues to affect this land and its surrounding areas. The "thousand-year eruption" of Baekdusan volcano formed today's Cheonji Lake, symbolizing the intertwining of the power of nature and history.
The volcanic characteristics of the "Millennium Eruption" are two stages. The first stage of the Plinian eruption produced a large amount of volcanic ash and created a layer of sediment covering a vast area.
History of eruptions
The "Millennium Eruption" of Mount Baekdu occurred in 946, causing about 13 to 47 cubic kilometers of lava to erupt, forming today's Cheonchi. This event is known for its intensity and its long-term impact on the ecology and environment of the surrounding area. According to historical records, abnormal meteorological phenomena were observed in many places in South Korea and Japan at that time, and these phenomena may be related to the eruption.
One night in 946, white volcanic ash falling like snow appeared in Nara, revealing the direct consequences of the volcanic eruption.
Detailed analysis of volcanic eruption process
Based on the study of sedimentary records, the eruption went through two phases. The first stage was a stable Plinian eruption, estimated to reach a height of 30 to 40 kilometers, and produced a large amount of light-colored pumice ash. Subsequently, the gravitational collapse accompanying the eruption produced massive pyroclastic flows covering thousands of square kilometers.
The first-stage volcanic ash layer not only affected the local ecology, but also became important evidence for studying the event.
Environmental and climate impacts
This eruption was not just a geological event, but also had an impact on the climate at the time. Research shows that volcanic eruptions can release large amounts of aerosols and volatile materials, causing so-called volcanic winters. Between 946 and 948, many areas experienced climate anomalies, which were speculated to be related to the eruption of Mount Paektu.
The Millennium Eruption may have had a major impact on the climate at the time, although recent research suggests its impact may have been primarily regional.
Inspiration for the future
As time passes, Mount Paektu’s “Millennium Eruption” reminds us how unpredictable the power of nature can be. The Tianchi we see today is a testimony of volcanic activity and the eternal changes in nature between heaven and earth. How should we view these natural phenomena and reflect on the relationship between humans and nature?
