The mystery about the largest earthquake recorded on Mars is clarified, it was recorded by NASA's InSight lander, it occurred on May 4, 2022 And the truth is that it was not something terrible, it reached a degree of 4.7, although it caused vibrations that reverberate throughout the planet for at least 6 hours.



Because the seismic signal was similar to previous earthquakes known to have been caused by asteroid impacts, researchers believed that this event called S1222a could have also been caused by an impact. So a search was launched to find the new crater. which is not easy at all since Mars has about 144 million square km, but there were some clues to locate it.

The two largest recent impacts formed craters of about 150 m in diameter, so the supposed impact that caused the earthquake must have been larger, it would have created a crater of about 300 m in diameter, and the ejected material should have been clearly visible and perhaps A large dust cloud could even be captured in the photos taken hours after the earthquake.



For months the ships orbiting the red planet were searching the surface and found nothing, now they have ended the investigation, which is why a global team of scientists led by the University of Oxford in the United Kingdom announced on October 17 that the The conclusion of the research is that the largest earthquake recorded on Mars had its origin not outside the planet due to the impact of an asteroid, but rather the cause was inside Mars and the tectonic forces that are still active.



This indicates that the Red Planet is much more seismically active than previously thought, although researchers continue to believe that Mars does not currently have active tectonic plates like Earth does, so this event was likely caused by the release of tension within of the Martian crust.
