“内生月震”导致月球上新增数十处滑坡

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]
