According to a new study, the moon is narrowing, causing wrinkles on the surface and moonshakes.
According to a NASA-sponsored study, as the moon's interior cools, it shrinks, causing cracking of its hard surface and the formation of fault lines. The moon has lost about 150 feet in the last hundred million millions of years.
NASA posted a video on Twitter showing fault lines on the surface of the moon.
Astronauts have placed seismometers on the moon during a series of past missions. Scientists, who determined that moon tremors were close enough to fault lines to establish causality, published their analysis in a study published Monday by Nature Geoscience, according to NASA. The space agency has also recorded traces of fault lines in a series of images.

"Our analysis shows for the first time that these faults are still active and are likely to produce moonshade today, as the moon continues to cool and shrink gradually," said Thomas Watters, lead author from the study and principal scientist of the Smithsonian Center for Earth National Museum of Air and Space, according to a press release published on the NASA website.
Watters says earthquakes can be strong around five on the Richter scale, according to NASA's statement.
You have heard of earthquakes. But what about moon tremors? Like a wrinkled grape that dries into a grape, the Moon shrinks as its interior cools, causing wrinkles or defects to form on its fragile surface. When the stress generated is sufficient, it releases the earthquakes: https://t.co/H3ixgywT1p pic.twitter.com/OxNrVveAQk
