Scientists at ETH Zurich have been monitoring the seismic pings of more than 1,300 marsquakes ever since the NASA InSight Mission placed the SEIS seismometer on the surface of Mars in 2018.
An international team of scientists led by ETH Zurich examined a cluster of more than 20 recent marsquakes that were caused by the Cerberus Fossae graben system
Scientists concluded from the seismic data that the low-frequency quakes point to a potentially warm source that may be explained by magma at that depth that is now molten, or by volcanic activity on Mars.
The Cerberus Fossae Mantling Unit is surrounded by darker deposits of dust in all directions, not just the direction of the prevailing wind.
Other than Earth, Mars is the only planet where researchers have ground-based rovers, landers, and more recently, data-transmitting drones.
It gives geophysicists and seismologists a chance to work with up-to-date information about what is occurring on Mars right now, both on its surface and inside.
The only planet that we are aware of that contains an iron, nickel, and sulfur core and may have once supported a magnetic field is the red planet
The Tharsis Montes region, the greatest volcanic system in our solar system, and the Olympus Mons, a volcano with roughly three times the height of Mount Everest, were both created as a result of the long enough eruption of volcanic debris.
Stähler suggests that what we are seeing may be the final traces of this once-active volcanic area or that the magma is currently flowing eastward to the next eruptive site.
