Uncovering the Surprising Source of Mars' Largest Quake

The source of a massive quake on Mars, detected by NASA's InSight lander, has surprised scientists. Mars, which was believed to lack tectonic plates, experienced colossal tectonic activity in its crust, according to a study led by Benjamin Fernando of the University of Oxford. The leading alternative explanation, a meteorite impact, was ruled out. The findings suggest that Mars is more seismically active than previously thought, although further exploration is needed to fully understand the planet's geological processes.
