The Moon’s Surface Is Shrinking and Earthquakes Happen on the Moon

The Moon’s interior continues to cool, causing contractions to occur on the Moon, according to a new study. These shrinkages have been going on for millions of years, and the surface lost due to shrinkage is about 50 meters. These contractions cause cracks in the hard outer surface of the Moon. This creates fault lines on the Moon, and as a natural consequence of this, earthquakes occur on the Moon. A section was created on NASA’s official website about the research and a video was shared on YouTube. In the information on NASA’s website, this situation on the Moon is likened to a grape. We can say that the gradual shrinking of a grape as it starts to dry is an example of the situation on the Moon.


NASA left seismometers on the Moon’s surface on the Apollo 11, Apollo 12, Apollo 14, Apollo 15 and Apollo 16 missions. The first of these seismometers, of which there are 5 in total, was left during the Apollo 11 mission, but this seismometer only worked for three weeks. Thus, at the moment, 4 seismometers are actively working on the lunar surface. These working seismometers recorded 28 large and small earthquakes from 1969 until 1977. The magnitudes of these earthquakes ranged from 2 to 5.

NASA also shared images of the fault lines visible on the Moon’s surface. Here is a fault line on the lunar surface;


The video shared by NASA on YouTube is as follows;

If you say these are not enough for me, you can go to NASA’s original page and examine all the details.
