Approximately 10,000 years ago, a significant asteroid impact occurred in what is now Guangdong Province, China. This event has been confirmed through the discovery of the Jinlin crater, a large bowl-shaped structure near Zhaoqing. The crater, with a diameter of about 900 meters, is the fifth confirmed impact crater in China and the first in the southern region. South China Morning Post
The Scale of the Impact
Scientists estimate that the asteroid responsible for the Jinlin crater was approximately 30 meters in diameter. The energy released upon impact is estimated to be 600,000 tonnes of TNT, equivalent to the explosive power of 40 Hiroshima-sized atomic bombs. South China Morning Post
Geological Significance
The discovery of the Jinlin crater provides valuable insights into the Earth’s geological history and the frequency of asteroid impacts. While the impact occurred long before recorded human history, it serves as a reminder of the potential hazards posed by near-Earth objects.
Conclusion
The confirmation of the Jinlin crater as the site of a significant asteroid impact 10,000 years ago enhances our understanding of Earth’s geological history. It underscores the importance of continued monitoring of near-Earth objects to assess potential threats to our planet.
