Scientists at the Australian National University have suggested that volcanic activity is the cause of recurring marsquakes in a certain region of the Red Planet. This is reported in an article published in the journal Nature Communications.
The researchers recorded 47 previously undetected events of seismic activity under the Martian crust in the Cerberus Fossae region, which is less than 20 million years old. The data obtained by the instruments on the InSight lander indicate that the magma in the Martian mantle between the crust and the core is still active and is responsible for tectonic processes.
Mars quakes have been detected over a period of regarding 350 sols, equivalent to regarding 359 days on Earth. The presence of seismic activity indicates the existence of convection of mantle rocks in the depths of Mars, which makes it more difficult to explain why there is no magnetic field on the Red Planet. Most likely, there is another mechanism that prevents its generation.
