Shrinking moon may be generating moonquakes

A new analysis suggests that the moon is actively shrinking and producing moonquakes along thousands of cliffs called thrust faults spread over the moon's surface. The faults are likely the result of the moon's interior cooling and shrinking, causing the surface crust to shrivel and crack like a raisin's skin.
