Even the moon has seismic activity

I thought about the Mahdi

Analysis of the data of the four observing stations installed by the astronauts in the Apollo missions revealed new evidence suggesting tectonic activity in the moon, after it was believed that the moon is a dead rock mass.

A recent study, published in the journal Nature Earth Studies, revealed the observation of lunar surface earthquakes - with a intensity ranging from two to five degrees on the Richter scale - directly related to the places of high fissures slopes.

These fractal lunar slopes take the stairs shape, usually tens of meters high and span a few miles.

Lunar Cracks
The study team developed a computer algorithm to locate the 28 surface earthquakes detected, which are likely to occur between 1969 and 1977.

The team found that eight of them had occurred within 30 km of the cracks appearing in the lunar imagery, which gives a logical justification for considering it a major reason behind the occurrence of these earthquakes.

The study found that six of the eight earthquakes occurred when the moon was at the farthest point from Earth in its orbit, as the additional tidal wave due to gravity increases, increasing the possibility of slippage in those seismic fissures. 

Detailed Images
NASA's LRO spacecraft provided detailed images that revealed more than 3,500 cracks on the moon's surface.

Some of these images show landslides in spots that appear relatively bright compared to the surface of the moon, which appears dark in color due to its influence by solar and space rays, which gives further evidence that these bright areas have resulted from the slipping of some rocks to the bottom of the rift slope as a result of an earthquake in those cracks Active.

Another major avalanche of the southern rock mass from the slope of Lee Lincoln is further evidence of the presence of lunar earthquakes caused by the occurrence of fracture cracks there.

The origin of the moon's origin The
rocks expand as the temperature rises and shrinks at the coolness. As a result of their shrinkage, the crust of the moon breaks to form cracks, as was observed by the detailed photos taken by the exploratory spacecraft in 2009.

The study team has been comparing images of specific cracks at different times, to see if there is any evidence of recent seismic activity.

And the moon is not the only one in our solar system that has suffered some contraction over time. Where there are enormous cracks in Mercury, about six hundred miles long, more than three kilometers high, and they are much larger in size than those on the moon, which indicates that Mercury shrank by far more than the moon.

This information encourages the establishment of a new seismic network on the surface of the moon to learn more about its interior, and to determine the amount of dangerous earthquakes there, in addition to the need to identify the active faults to avoid their contiguity when planning to prepare space bases there.
