There was only one seismic station on the InSight mission. The determination of the coordinates and depth of the marsquakes were performed with great uncertainty, represented by ellipsoidal probability density functions. The nature of Martian seismic activity is uncertain. Many marsquakes are thought to be triggered by seismic sources such as faults or cracks. The gravitational potential of Mars is largely determined by long-wave components and mainly reflects the influence of a massive regional anomaly — the Tharsis bulge. At depths of 100–200 km the predominant contribution to the general stress state is made by the short-wave part of the gravitational field, while long-wave components do not allow localizing stresses associated with specific geological formations. Here we show that global compression and stretching created by the Tharsis zone is not the dominant process.
