Rapid City‐Scale Earthquake Assessment by Combining Numerical Simulation and Sparse Sensing

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
This study proposes a framework to assess the seismic risk by integrating city‐scale numerical simulations with sensor data prediction. The study begins with advanced numerical simulations using two primary methods: the integrated earthquake simulator (IES) and the stochastic Green's function method.

Automated Three‐Dimensional Reflection Traveltime Modelling to Extract 3D Dipping Layer Geometries

open access: yesGeophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT Steep geological structures are critical for improved understanding of tectonic processes and fluid circulation, particularly in crystalline settings. However, accurately determining their geometry at depth remains a challenge for conventional 2D surveys.

Is the Deep Martian Mantle Heterogeneous? A Reappraisal of Seismological Evidences

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract It has been proposed that the deep Martian mantle contains distributed heterogeneities preserved since the accretion of the planet. This result relies on a multiple‐scattering interpretation of frequency‐dependent arrival times of P $P$‐waves detected in the spectrograms of teleseismic Martian events.
