After finding low-frequency quakes in the planet's interior, scientists concluded that volcanism, or volcanic activity, still shapes the Martian surface
The scientists examined more than 20 marsquakes from the Cerberus Fossae graben system, a series of rifts
ETH Zurich, Harvard University, Nantes Université, CNRS Paris, German Aerospace Center in Berlin, and Caltech conducted the Nature Astronomy investigation
Scientists only have ground-based rovers, landers, and data-transmitting drones on Mars.
Scientific assumptions can be made with more certainty thanks to the seismic data and orbital photos.
"Mars, one of our closest neighbors on the planet, helps us comprehend how Earth's geological processes are similar to those of Mars.
Additionally, topographical data suggests that Mars once had extensive areas of water and perhaps a denser atmosphere.
It said it spewed volcanic material long enough to create Tharsis Montes, the greatest volcanic system in our solar system, and Olympus Mons, a volcano roughly three times the height of Mount Everest.
The remaining vestiges of this formerly active volcanic region could be what we are seeing, or the magma could be on its way east to the next eruption site, according to Staehler.
