Surface waves and crustal structure on Mars

D Kim, WB Banerdt, S Ceylan, D Giardini, V Lekić… - Science, 2022 - science.org
We detected surface waves from two meteorite impacts on Mars. By measuring group
velocity dispersion along the impact-lander path, we obtained a direct constraint on crustal …

Crustal anisotropy in the Martian lowlands from surface waves

C Beghein, J Li, E Weidner, R Maguire… - Geophysical …, 2022 - Wiley Online Library
The largest seismic event ever recorded on Mars, with a moment magnitude of 4.7±0.2, is
the first event to produce both Love and Rayleigh wave signals. We measured their group …

Different Martian crustal seismic velocities across the dichotomy boundary from multi‐orbiting surface waves

J Li, C Beghein, P Lognonné… - Geophysical …, 2023 - Wiley Online Library
We have observed both minor‐arc (R1) and major‐arc (R2) Rayleigh waves for the largest
marsquake (magnitude of 4.7±0.2) ever recorded. Along the R1 path (in the lowlands) …

EARA2024: a new radially anisotropic seismic velocity model for the crust and upper mantle beneath East Asia and Northwestern pacific subduction zones

Constraining the 410-km discontinuity and slab structure in the Kuril subduction zone with triplication waveforms

J Li, M Chen, J Ning, T Bao, R Maguire… - Geophysical Journal …, 2022 - academic.oup.com
The detailed structure near the 410-km discontinuity provides key constraints of the dynamic
interactions between the upper mantle and the lower mantle through the mantle transition …

Ultra-low-velocity anomaly inside the Pacific Slab near the 410-km discontinuity
