On the lunar surface, moonquakes are being caused by technology that was left over from Apollo 17.

The effects of daily temperature changes are what produce the tremors on the lunar surface.

NASA astronauts Gene Cernan and Harrison Schmitt left a few items behind, including a US flag, a Moon buggy, and the lunar module's descent stage.

The study is done by scientists at the California Institute of Technology.
