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]

Core Insights - The research conducted by a 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 findings were published in the journal "National Science Review" and indicate that the Moon still has internal energy activity [2] Group 1: Research Methodology - The team utilized satellite imagery with a resolution of less than 1 meter per pixel to compare pre- and post-event images, identifying new landslide locations and characteristics [1] - A total of 74 observation areas were selected, including steep crater walls and regions with potential recent volcanic activity, to assess landslide activity [1] Group 2: Characteristics of Lunar Landslides - The newly identified landslides on the Moon are described as "small" and "superficial," with most being less than 1 kilometer in length and under 100 meters in width [2] - The volume of material displaced by each landslide is less than 100,000 cubic meters, primarily occurring on slopes with inclinations between 24° and 42° [2] Group 3: Causes of Landslides - The research indicates that while many new impact craters have formed, less than 30% of the new landslides are triggered by these impacts, suggesting that internal seismic activity is the main cause [2] - The study implies that the distribution of lunar landslides can serve as a guide to locate active seismic zones beneath the Moon's surface [2]

和地球上的大型滑坡不同，月球上的新滑坡显得"小巧"且"浅表"：大多数滑坡长度不到1公里，宽 度不足100米，最厚的地方不到1米。从规模上看，每处滑坡移动的物质的体积都小于10万立方米，且主 要集中在坡度24-42度的斜坡上。 肖智勇团队分析了这些新滑坡的地质情况，发现了大量新形成的撞击坑，最大的直径超过70米。但 是，不到30%的新滑坡可能是由撞击触发，且滑坡开始的位置普遍缺乏暴露的岩石。因此，科学家推 断，这些滑坡主要是由内生月震引发的震动导致的，证实月球内部仍有能量活动。 "这些内生月震驱动的新滑坡，主要集中在月球雨海盆地的东部区域，而这里恰好是过去阿波罗探 月任务中记录到浅层月震较多的地方。这意味着雨海盆地东部可能是月球当前的月震活跃区。"肖智勇 说。 肖智勇表示："未来如果要在月球建立长期基地，我们应该避开这类月震活跃的区域，选择更稳定 的地点。" 据中山大学13日消息，中山大学大气科学学院肖智勇团队联合遥感科学与技术学院教授张吴明通过 卫星图像分析，发现2009年以来月球上新增了数十处滑坡，而这些滑坡的主要"推手"，不是小行星撞 击，而是月球内部产生的地震，也就是科学家所称的"内生月震"。 该成果近 ...
