Chinese scientists have discovered new lunar landslides on the Moon, revealing previously unknown active seismic zones. These lunar landslides, forming since 2009, shed light on the Moon’s internal activity and surface dynamics. Researchers found that most of these landslides result from endogenic moonquakes rather than asteroid impacts.
The study, conducted by Sun Yat-sen University in Guangdong Province, examined multi-temporal images of the Moon’s most unstable regions. The researchers concentrated on minor, shallow moon slope failures, each moving less than 100,000 cubic meters of material. Most of these events were under one kilometer long and 100 meters wide.
Researchers also examined the geological conditions around the lunar landslides. They identified numerous new impact craters, some over 70 meters wide. However, fewer than 30 percent of the landslides were linked to these impacts. Instead, endogenic moonquakes appear to have triggered the majority, especially in the eastern Imbrium basin.
The results show clear clustering of moon slope failures, suggesting uneven seismic activity within the Moon. Experts note that this spatial pattern could help pinpoint active seismic zones more precisely. Previously, deep seismic regions were mostly undetectable, leaving significant gaps in knowledge of lunar geology.
Lead researchers noted that studying lunar landslides provides a strategy for future seismometer placement. Targeted deployments could improve understanding of the Moon’s internal structure and reduce risks for future missions. Engineers can now consider landslide-prone areas when planning lunar landings.
Beyond immediate exploration, the research highlights broader scientific implications. Investigating lunar landslidesenhances understanding of planetary geology and seismic processes on other celestial bodies. This knowledge could support future missions to Mars, asteroids, and other moons.
Chinese space agencies have increasingly emphasized lunar research, using satellite imaging and in-situ investigations. Monitoring lunar landslides aligns with efforts to track seismic activity, surface changes, and human mission safety. Continued observation is expected to uncover more landslides and refine models of lunar surface dynamics.
In conclusion, lunar landslides offer a new perspective on the Moon’s internal activity. These discoveries underline the importance of endogenic moonquakes and guide the next steps in lunar research and exploration.
