For the first time, from early 2019 to the end of 2022, Mars' shallow and deep interiors have
been explored by seismology with the InSight mission. Thanks to the performances of its …

Geophysical evidence for an enriched molten silicate layer above Mars's core

H Samuel, M Drilleau, A Rivoldini, Z Xu, Q Huang… - Nature, 2023 - nature.com
The detection of deep reflected S waves on Mars inferred a core size of 1,830±40 km (ref.),

Structure along the Martian dichotomy constrained by Rayleigh and love waves and their overtones

D Kim, SC Stähler, S Ceylan, V Lekic… - Geophysical …, 2023 - Wiley Online Library
Using seismic recordings of event S1222a, we measure dispersion curves of Rayleigh and
Love waves, including their first overtones, and invert these for shear velocity (VS) and radial …

Focal Mechanism Determination of Event S1222a and Implications for Tectonics Near the Dichotomy Boundary in Southern Elysium Planitia, Mars

R Maguire, V Lekić, D Kim, N Schmerr… - Journal of …, 2023 - Wiley Online Library
Abstract On 4 May 2022 the InSight seismometer SEIS‐VBB recorded the largest marsquake
ever observed, S1222a, with an initial magnitude estimate of 4.6. Understanding the depth …

Constraints on the martian crust away from the InSight landing site

The most distant marsquake recorded so far by the InSight seismometer occurred at an
epicentral distance of 146.3±6.9 o, close to the western end of Valles Marineris. On the …

Crustal structure constraints from the detection of the SsPp phase on Mars

J Li, C Beghein, P Davis, MA Wieczorek… - Earth and Space …, 2023 - Wiley Online Library
The shallowest intracrustal layer (extending to 8±2 km depth) beneath the Mars InSight
Lander site exhibits low seismic wave velocity, which is likely related to a combination of …

A positive feedback between crustal thickness and melt extraction for the origin of the Martian dichotomy

V Bonnet Gibet, C Michaut, M Wieczorek… - Journal of …, 2022 - Wiley Online Library
A North/South difference in crustal thickness is likely at the origin of the Martian dichotomy in
topography. Recent crustal thickness maps were obtained by inversion of topography and …

Estimating primary magmas from Mars with PRIMARSMELT: Implications for the petrogenesis of some Martian rocks and the thermal evolution of Mars

JD Hernández‐Montenegro, PD Asimow… - Journal of …, 2024 - Wiley Online Library
Primary magmas form by partial melting in the mantle of a terrestrial planet and represent
the starting material for building its crust. The compositions of primary magmas are critical for …
