N1 - Funding Information: Our moment tensor inversion was based on a modified version of the MTUQ code package (https://github.com/uafgeotools/mtuq), and we thank the developers for making this tool openly available. Seismic data from the S1222a event, and other marsquakes, are available for download through the IRIS Data Management Center. This paper is InSight contribution number 290. The authors acknowledge the NASA, the CNES, their partner agencies and Institutions (UKSA, SSO, DLR, JPL, IPGP-CNRS, ETHZ, IC, and MPS-MPG) and the flight operations team at JPL, SISMOC, MSDS, IRIS-DMC, and PDS for providing the SEED SEIS data. D.K. acknowledges support from the ETH+ funding scheme (ETH+02 19-1: “Planet Mars”). N.S. and V.L. were supported by NASA Grant 80NSSC18K1628. C.B. and J.L. were funded by NASA InSight PSP Grant 80NS-SC18K1679. P.L acknowledges support from CNES and ANR (ANR-19-CE31-0008-08 MAGIS, ANR-18-IDEX-0001). JCEI acknowledges support from UKSA Grant ST/W002515/1. We thank Göran Ekström and Julien Thurin for their thorough and constructive reviews that helped improve this manuscript.
