Moon's Shrinking Surface May Lead to Future Moonquakes

Researchers at the National Air and Space Museum's Center for Earth and Planetary Studies have created a comprehensive map of small mare ridges (SMRs) across the Moon's maria, revealing young and significant tectonic activity. These ridges, formed by compressional forces, differ from previously known lobate scarps by their location in the lunar maria. By examining these structures, scientists have also highlighted potential new sources of moonquakes, essential for future lunar missions. This research enhances understanding of the Moon's interior, as well as its thermal and seismic history, offering crucial insights for upcoming exploration programs like Artemis.
