Cerberus Fossae, a set of semi-parallel fault cracks separating the Mars crust, has been identified as the first active seismic zone discovered on the Red Planet.

NASA's InSight seismometer, called Seismic Experience for Interior Structures (SEIS), focused on this huge tectonic structure, the epicenter of two major MarsQuakes – Martian earthquakes – detected during mission suns 173 and 235.

According to Europa Press, Cerberus Fossae measures 1,235 kilometers in diameter. The magnitudes of both tremors were between 3 and 4 on the Richter scale, according to the information provided in Twitter SEIS team prior to publication of the research in scientific journals. The first "big" earthquake occurred in May and the second in July this year.

Due to thermal variations and winds, Mars is a noisy place. However, between 5 pm and shortly after midnight, the Red Planet becomes very quiet. It is at these times that the seismometer can monitor all frequencies with crystal clarity, including invisible bands on Earth.

Even though the Red Planet looks petrified, Mars continues to "crash." The rate of earthquakes continues to rise without geophysicists understanding why. Still, the earthquakes on Mars are very weak.
