The Moon is steadily Decreasing, Resulting in wrinkling on its surface and quakes, Based on an analysis of Vision captured by NASA’s Lunar Reconnaissance Orbiter (LRO) Printed Monday.
Contrary to our world, the Moon does not have tectonic plates; instead, its tectonic activity occurs as it gradually loses heat from when it was formed 4.5 billion years back.
This in turn causes its surface to wrinkle, similar to a grape which shrivels into a raisin.
Considering that the moon’s crust is brittle, these forces cause its surface to break because the interior shrinks, resulting in so-called thrust faults, where a single section of crust has been pushed up within an adjacent section.
Because of this, the Moon is now about 150 feet (50 meters)”skinnier” within the last several hundred thousand years.
The Apollo astronauts first started measuring seismic activity on the Moon in the 1960s and 1970s, finding the vast majority were happened deep in the human body’s inside while a smaller number were on its own surface.
The analysis has been published in Nature Geoscience and analyzed the shallow moonquakes recorded from the Apollo missions, establishing connections between them and very young surface attributes.
“It is quite likely that the flaws are still active now,” said Nicholas Schmerr, an assistant professor of geology in the University of Maryland who co-authored the study.
“You do not often get to view active tectonics anywhere but Earth, therefore it’s very exciting to think these faults may still be producing moonquakes.”
