Scientists discover recent tectonic activity on the moon
Summary
Scientists report the first global map and analysis of small mare ridges on the Moon, showing recent tectonic activity. The ridges are geologically young and widespread across the lunar maria, with 1,114 new SMR segments (2,634 total) and an average age of about 124 million years. The findings imply ongoing contractional tectonics and raise the possibility of moonquakes near SMRs, which has implications for future lunar exploration and landing-site selection.
