The moon may be tectonically active, and geologists are shaken

“The whole idea that a 4.6-billion-year-old rocky body like the moon has managed to stay hot enough in the interior and produce this network of faults just flies in the face of conventional wisdom,” says study coauthor Thomas Watters of the Smithsonian Institution in Washington, D.C. Since 2009, Watters has been using images from NASA’s Lunar Reconnaissance Orbiter to map thousands of scarps all around the moon. Of the 28 recorded events, eight might have occurred within around 18 miles of a scarp, and six of those happened when the moon was at its farthest point from Earth, just when tidal stresses on the lunar surface should peak.
