"Shrinking Moon Triggers Moonquakes and Instability Near Lunar South Pole"

Scientists have discovered that the moon has been shrinking over the last few hundred million years, causing surface warping and the formation of faults in its south polar region. This shrinkage has led to notable instability and the potential for landslides, particularly in areas proposed for crewed Artemis III landings. Shallow moonquakes, caused by faults in the moon's interior, can last for hours and pose dangers to future human exploration efforts. The study's lead author emphasized the importance of considering the potential for ongoing global contraction and the formation of new thrust faults when planning the location and stability of permanent outposts on the moon.
