Seismic waves carry information about both the source processes (e.g. impacts, landslides, fault ruptures, etc.) that gave rise to them and the conditions and structures in inaccessible planetary interiors that they traverse. On Earth, identification of specific seismic phases, structural imaging, and source characterization all benefit from seismic networks and robust knowledge about the first order properties of the interior. Single station recordings, like those provided by NASA's InSight mission, present unique but surmountable challenges to extracting this scientifically important information. Here, I review some key insights into the seismicity and deep interior structure of Mars, focusing on discoveries about the lower mantle and the characteristics of the largest recorded marsquake.
