    The mega-marsquake, which is 5 times stronger than the previous record, may be the last big find from the InSight Mars Lander.
     
    A Marsquake detected by NASA's InSight lander this year was at least five times larger than the next largest seismic event recorded on the planet.
     
    The quake occurred registered at a magnitude of 4.7, five times more powerful than the InSight lander's previous largest quake on Mars back in August 2021, which was recorded at a magnitude around 4.2.
     
    Another indication of the scale of the event is that InSight continued detecting waves from the record-breaking quake for around 10 hours, while the after-effects of all previous Marsquakes had subsided within an hour.
     
    "The energy released by this single marsquake is equivalent to the cumulative energy from all other Marsquakes we've seen so far," John Clinton, a seismologist at the Swiss Federal Institute of Technology in Zürich and co-author of the study, said in a statement from the American Geophysical Union, which published the research. "Although the event was over 2,000 kilometers (1,200 miles) distant, the waves recorded at InSight were so large they almost saturated our seismometer."
