• Science Moonquakes: Understanding the Moon’s Tectonic Forces Could Protect Future Astronauts Space agencies and companies looking to set up lunar outposts should build far away from seismic activity. • The brighter areas are the lunar highlands. • The darker areas are the lunar maria. • As humanity looks to the moon for science and economic opportunity in the coming years, understanding potential dangers lurking on the lunar surface could become increasingly important. • Ridges on the moon that signify moonquakes are the subject of a recent researchpaper, which delves into tectonic activity across the lunar maria, a vast network of dark plains that arose from ancient volcanic activity. • A team of researchers analyzed lunar formations called small mare ridges to create a global moon map, which is the first of its kind.
Article Summaries:
- A new study published in the Planetary Science Journal presents the first global map of small ridges in the Moon’s maria, features linked to subsurface faults that generate moonquakes. Researchers, including postdoctoral fellow Cole Nypaver and scientist Tom Watters, argue that the ridges form as the Moon’s cooling core contracts, compressing the crust and pushing material upward. The work expands knowledge of lunar tectonics beyond the highlands, suggesting a more extensive recent contraction than previously thought. The findings are timely as NASA’s Artemis program plans to deploy seismic stations-such as the Lunar Environment Monitoring Station on Artemis 3-to monitor future seismic hazards for long‑term lunar outposts.
