Mars earthquakes uncover hidden features
A recent study analyzing earthquakes and vibrations recorded by NASA's InSight lander has revealed the presence of a thick, sub-surface layer of magmatic magma beneath the surface of Mars, reaching a thickness of up to 14 kilometers. This magmatic system is believed to explain the unexpected variations in seismic wave speeds and to challenge previous notions about the planet's internal structure, suggesting that Mars can maintain a complex crust without active tectonic movement. The discovery sheds light on the potential of planets to sustain environments conducive to life and broadens our understanding of the geological formation processes of rocky planets.
