The Marsquake Service (MQS) will be one of the ground segment services within the InSight mission to Mars, which will deploy a single seismic station on Elysium Planitia in November 2018. The main tasks of the MQS are identification and characterisation of seismicity, and managing the Martian seismic event catalogue. In advance of the mission, the InSight team have developed a series of single-station event location methods using i) multi-orbit surface waves, and ii) differential body and surface wave arrival times relying on (initially a priori) 1D and 3D structural models (Panning et al., 2015; Bozdag et al, 2016, Boese et al., 2017). These methods have been included in the operational MQS software framework. In coordination with the Mars Structural Service (Panning et al, 2016) who will provide the Martian Structure models catalogue, we expect to use iterative inversion techniques to revise these structural models and event locations (Khan et al., 2016; Panning et al., 2016). In this presentation, we introduce the methods and procedures that are being developed by the MQS in order to provide a seismicity catalogue using only the single seismic station on Mars.
