Don’t shoot for it: shrinking moon sees hours-long quakes and landslides

The constancy of the moon in the night sky belies a more volatile reality, researchers said in new Nasa-funded research. As the core of the Earth’s only natural satellite cools, the moon is shrinking, causing it to shrivel. That creates ripples tens of meters high, called thrust faults, across the moon’s surface. In turn, those thrust faults can be the site of hours-long moonquakes and landslides, which could imperil people and robots as humans continue to explore the moon.
