Key takeaways The quake lasted four hours and identified layering in the crust that could indicate a meteoroid impact. The 4.7 magnitude temblor happened in May 2022 and released five times more energy than any previously recorded quake on Mars. Mapping the seismic activity on Mars will help inform scientists where and how to build structures to ensure the safety of future human explorers. The largest earthquake ever detected on Mars has revealed layers in its crust that could indicate past collision with a massive object, such as a meteoroid. Previous data has suggested the past occurrence of a large impact, and the findings offer evidence that might support this hypothesis. The research, led by UCLA planetary scientists and published in papers in Geophysical Research Letters, could also indicate that alternating layers of volcanic and sedimentary rocks lie beneath the surface.
