研究发现月球上新增数十处滑坡

Core Insights - The research conducted by the team from Sun Yat-sen University reveals that since 2009, dozens of new landslides have formed on the Moon, primarily triggered by internal seismic activity rather than asteroid impacts [1][2] - The study utilized high-resolution satellite imagery to identify and analyze these landslides, providing insights into the Moon's geological activity [1] Group 1: Research Findings - The team identified 74 observation areas on both the near and far sides of the Moon, focusing on steep crater walls, fault-formed ridges, and irregular lunar mare patches that may indicate recent volcanic activity [1] - Most of the newly formed landslides are small, with lengths under 1 kilometer and widths less than 100 meters, and the largest volume of material displaced is less than 100,000 cubic meters [1] Group 2: Causes of Landslides - Analysis of the geological conditions revealed that less than 30% of the new landslides were triggered by impacts, with many starting points lacking exposed rock [2] - The primary cause of these landslides is inferred to be internal lunar seismic activity, indicating ongoing energy processes within the Moon [2] Group 3: Implications for Future Research - The distribution of lunar landslides can serve as a guide to identify active seismic zones beneath the Moon's surface, aiding in the future deployment of lunar seismometers and studies of the Moon's internal structure [2]
