SEIS on Mars: First Legacy after Four Years of Seismic Monitoring of Mars

SEIS, the international seismometer of NASA?s InSight mission, operated on Mars from February 20 19 until mid- December 20 22. For the first time, a robotic seismometer installation was made on the ground followed by wind shield deployment. We present results in term of anisotropy, attenuation and scattering. Seismic source analyses have determined magnitude, depth and centroid moment tensors for the largest marsquakes and provided better understanding of impact processes, including partitioning of blast energy in the subsurface and atmosphere.
