We present a time-dependent geometry-informed neural operator (GINO) surrogate of LISFLOOD-FP for the municipality of Forlì (Italy), severely affected by the May 2023 Emilia-Romagna floods.

This article reviews how subtle changes in the Earth's subsurface can be detected and interpreted through variations in seismic wave propagation induced by external environmental processes, with applications to geomechanics, hydrology, and natural hazard assessment.

Recently, self-supervised learning methods remove the need for ground-truth velocity maps during training by leveraging a forward operator to simulate seismic data from predictions and backpropagate the gradients of reconstruction loss through it. In this work, we consider a more challenging setting without accessing such gradients.

Here we propose a novel model of coda wave generation with random fractures in the lunar crust, where vacuum fractures prevent seismic wave propagation as insulating boundaries, causing strong persistent reverberation in terms of total reflection among fractures.

At a deep (800-1000 m) and a shallow (65 m) CO2 storage site, each approach reduces the computing time about 700-fold, and the filtered simulation gives the same hit rate as a full one, as long as the margin exceeds the muons' sideways scattering drift.

We present GeoSim, a benchmark of high-resolution two-dimensional mantle-plume simulations generated with I2VIS, comprising 237 trajectories across two parameter regimes, with six coupled fields, physical timestamps, and trajectory-level splits.

We present FA-Agent, an agent framework for first-arrival picking built on a multimodal large language model.

Using direct numerical simulations of homogeneous Boussinesq turbulence, we investigate Lagrangian power statistics across four local velocity-gradient topology classes and three nonzero stratification strengths, with an unstratified reference case.

Quantum circuit simulators are essential for quantum algorithm development, yet systematic runtime benchmarks comparing major frameworks across CPU and GPU backends are limited.

Comparison with nearby Global Navigation Satellite System (GNSS) observations demonstrates that the method reliably captures the amplitude and orientation of permanent tectonic displacements.

This study presents an integrated approach combining seismic refraction tomography and electrical resistivity tomography to evaluate the structural integrity of supporting pillars in an underground cave in Burgundy, France.

We developed a spatial autocorrelation (SPAC) method for estimating Rayleigh-wave attenuation coefficients using an attenuation-aware formulation of the SPAC coefficient.

This study aims to protect an exceptional population of soda straw stalactites from vibrations generated by nearby rock blasting activities.

We conducted passive seismic monitoring of the unstable La Praz rock slope (approximately 14,000 m${}^3$) in the French Alps over a period of more than 10 years.

Induced polarization (IP) offers a valuable complementary approach for investigating the petrophysical properties of geological materials.

Repeated passive seismic surveys were conducted over more than a decade on the unstable La Praz rock slope in Savoie, France, which involved an estimated rock volume of approximately 13,000--15,000 m${}^3$.

We investigate how a dense, low-viscosity droplet deforms in a lighter, much more viscous host under shear and gravity, using 96 two-dimensional Level-Set simulations.

We introduce fluctuations into the energy balance to develop a stochastic model that captures the main features of the broadening transport distribution.
