The first of a series of papers making use of data from InSight event S1222a, the largest ever recorded, was published in Geophysical Research Letters with C. Beghein as the first author:
Beghein, C., Li., J., Weidner, E., Maguire, R., Wookey, J., Lekic, V., Lognonné, P., and Banerdt, W. (2022), Crustal Anisotropy in the Martian Lowlands from Surface Waves, Geophys. Res. Let., 49, 24, e2022GL101508, doi:10.1029/2022GL101508
Summary Points:
- Rayleigh and Love waves were detected on Mars
- Seismic wave speed is directionally dependent over large scales within Mars crust
- The shear wave horizontal velocity is faster than the vertical velocity at 10–25 km depth in the lowlands between the event and the lander
