Just like on Earth, the surface of Mars sometimes vigorously shakes and unsurprisingly, that is called a marsquake. The largest ever marsquake recorded in history happened in 2022 and scientists now finally know the reason behind it. A study published in the journal Geophysical Research Letters on Tuesday rules out the possibility that the marsquake was caused by a meteor impact. The quake had a magnitude of 4.7 and since its seismic signal was similar to previous quakes that were caused by meteoroid impacts, scientists initially believed that it might have been caused by an impact as well. This launched an international search for a fresh crater at the time.
