Reportedly the strongest recorded tremor has so far left no visible traces on the Martian surface, scientists said. If there is an earthquake on earth for 5 minutes, it will shake. Scientists have revealed that there was a six-hour continuous Marsquake on Mars in 2022. A vibration on the earth is called an earthquake or an earthquake. This vibration occurring on the same Mars is called Marsquake. An international team of scientists led by the university of Oxford has unveiled the source of the largest seismic event ever recorded on Mars. The research, published in the journal Geophysical Research Letters, completely rules out the possibility of a meteorite impact. Instead, it has been reported that this vibration is more likely to be caused by massive tectonic forces within the crust of Mars. The seismic event, known as 'S1222a', had a magnitude of 4.7 and shook the Martian surface for at least six hours. It was discovered by NASA's InSight lander on May 4, 2022.

Given the similarity of its vibrational signal to previous tremors caused by meteorite impacts, the team initially suspected an impact source for this event and began a search through international space agencies for a new crater. Although Mars is smaller in size compared to Earth, it has a similar land surface due to the absence of oceans. To survey the vast expanse of 144 million square kilometers, Dr. Benjamin Fernando sought help from the european Space Agency, the Chinese National Space Agency, the indian Space Research Organization and the United Arab Emirates Space Agency. This is the first project in which all Mars orbiting missions have collaborated in a single project.

During the mission, InSight, co-designed by the university of Oxford, recorded at least eight Maersk Quake events caused by meteorite impacts. If S1222a had formed from the impact, the resulting crater would have been expected to be at least 300m in diameter. But, after several months of searching, the team had not found any new crater on Mars. The team concluded that the event was caused by the release of enormous tectonic forces within Mars' interior, suggesting that the planet is more vibrationally active than previously thought. "We still think that Mars has no active plate tectonics today, so this event may have been caused by a release of pressure within the Martian crust," said Dr. Fernando said.

The study's findings could have significant implications for future human habitation on Mars. "One day, this information may help us understand where it's safe for humans to live on Mars and where it's not!" Dr. Fernando said. international collaboration has highlighted the importance of having diverse instruments on Mars. S1222a will be one of the last events recorded by InSight before its mission ends in december 2022. The team is now applying knowledge from this study to future work, including upcoming missions to the moon and Saturn's moon Titan.
