NASA Shocked To Discover Cause Of Largest Mars Quake Ever Detected On The Red Planet
The marsquake in question had a magnitude of 4.7. While mild for Earth, it is considered to be quite strong for Mars. The cause of the two prior marsquakes left indelible imprints on the surface of the Red Planet in the form of meteorite impact craters. However, when scientists began looking for a new impact crater that would coincide with the latest seismic event, they were not able to find one.
Fernando added that there are faults that are active on Mars, but no active plate tectonic processes are going on anymore. However, he added that the faults could still trigger quakes.
"This represents a significant step forward in our understanding of Martian seismic activity and takes us one step closer to better understanding the planet's tectonic processes," remarked Constantinos Charalambous, co-chair of InSight's Geology Working Group.
NASA's InSight mission recorded 1,319 marsquakes during its four years of operation. Every seismic event recorded by InSight is considered a "valuable piece of the puzzle." However, this event plays a critical role in understanding the geological history on Mars, while shedding more light on its interior and evolution, according to Charalambous.
As NASA and other space agencies continue to work toward sending humans to inhabit the Red Planet, understanding seismic events like marsquake S1222a is crucial for the safety of those who dare to venture into the beyond.
