This session provides the opportunity for contributions that fall within the broad spectrum of Rock Physics and Environmental Petrophysics, but are not directly appropriate to any of the other proposed sessions. We solicit contributions on theory and simulations, instrumentation, laboratory experiments and field measurements, data analysis and interpretation, as well as inversion and modelling techniques.

Rock mass deformation and failure at different stress levels (from the brittle regime to the brittle-ductile transition) are controlled by damage processes occurring on different spatial scales, from grain (µm) to geological formation (km) scale. These lead to a progressive increase of micro- and meso-crack intensity in the rock matrix and to the growth of inherited macro-fractures at rock mass scale. Coalescence of these fractures forms large-scale structures such as brittle fault zones, rockslide shear zones, and excavation damage zones (EDZ) in open pit mining and underground construction. Diffuse or localized rock damage have a primary influence on rock properties (strength, elastic moduli, hydraulic and electric properties) and on their evolution across multiple temporal scales spanning from geological time to highly dynamic phenomena as earthquakes, volcanic eruptions, slopes and man-made rock structures. In subcritical stress conditions, damage accumulation results in brittle creep processes key to the long-term evolution of geophysical, geomorphological and geo-engineering systems.
Damage and progressive failure processes must be considered to understand the time-dependent hydro-mechanical behaviour of fault damage zones and principal slip zones, and their interplay (e.g. earthquakes vs aseismic creep), volcanic systems and slopes (e.g. slow rock slope deformation vs catastrophic rock slides), as well as the response of rock masses to stress perturbations induced by artificial excavations (tunnels, mines) and loading. At the same time, damage processes control the brittle behaviour of the upper crust and are strongly influenced by intrinsic rock properties (strength, fabric, porosity, anisotropy), geological structures and their inherited damage, as well as by the evolving pressure-temperature with increasing depth and by fluid pressure, transport properties and chemistry.
In this session we will bring together researchers from different communities interested in a better understanding of rock deformation and failure processes and consequence, as well as other related rock mechanics topics. We welcome innovative and novel contributions on experimental studies (both in the laboratory and in situ), continuum / micromechanical analytical and numerical modelling, and applications to fault zones, reservoirs, slope instability and landscape evolution, and engineering applications.

The upscaling of laboratory results to regional geophysical observations is a fundamental challenge in geosciences. Earthquakes are inherently non-linear and multi-scale phenomena, with dynamics that are strongly dependent on the geometry and the physical properties of faults and their surrounding media. To investigate these complex processes, fault mechanisms are often scaled down in the laboratory to explore the physical and mechanical characteristics of earthquakes under controlled, yet realistic boundary conditions.
However, extrapolating these small-scale laboratory studies to large-scale geophysical observations remains a significant challenge. This is where numerical simulations become essential, serving as a bridge between scales and enhancing our understanding of fault mechanics. Together, laboratory experiments, numerical simulations, and geophysical observations are complementary and necessary to understand fault mechanisms across different scales.
In this session, we aim to convene multidisciplinary contributions that address multiple aspects of earthquake mechanics, combining laboratory, geophysical, and numerical observations, including:

(i) the interaction between the fault zone and the surrounding damage zone;
(ii) the thermo-hydro-mechanical processes associated with all the different stages of the seismic cycle;
(iii) bridging the gap between the different scales of fault deformation mechanisms.

We particularly encourage contributions with novel observations and innovative methodologies for studying earthquake faulting. Contributions from early career scientists are highly welcome.

The session proposes a comparison of experimental case studies and thermal-hydraulic-mechanical-chemical (THMC) modeling on different rocks and rock masses. In detail, focus is posed on the comparison between the behavior of weak/soft rocks and brittle rocks.
Weak/soft rocks and rock masses (e.g., fault rocks, turbidites, complex geological units, Block-In-Matrix – BIM rocks, salts and sulphates) represent a challenge in several geoengineering contexts, due to their low strength, high heterogeneity, high proneness to drastic weathering or fracturing processes, and to the fact that they can develop time-dependent and water-interaction-dependent deformations (e.g., creep, swelling, squeezing).
Brittle rocks, on the other hand, require specific attention for the description and quantification of their complicated fracture behavior (e.g., dominant fracture mode, microcrack initiation and crack coalescence). This can be investigated through multiple laboratory techniques, including ultrasonic waves, X-ray tomography, 2-D and 3-D digital image correlation, and acoustic emissions to identify the initiation and progression of micro and macro cracks that form in the rock prior to failure.
Contributions will afford these topics across multiple scales, from/across Angström to basin scales, proposing applications for the stability of natural slopes and seacliffs and for the mitigation of geological risks in engineering projects. Among other applications, session will explore in detail applications related to the energy transition, including carbon capture and storage, subsurface energy storage, geothermal energy, non-carbon gas exploitation (e.g. helium and white hydrogen), wind energy, hydroelectric energy, solar energy and battery storage for smoothing of Intermittent Renewable Energy Sources (IRES).
The session collects contributions that integrate geological observations, investigation surveys, laboratory data and modeling of soft and brittle rocks and rock masses to offer a fruitful discussion about the THMC behaviour of these materials and to explore and foster the contribution of petrophysics and geomechanics in the improvement of sustainable energy and material resources in the transition to low-carbon energy and net zero.

The successful development of unconventional resources-from shale plays and tight gas sands to complex carbonates—relies fundamentally on a robust understanding of their unique petrophysical properties. Traditional formation evaluation methods often fall short in addressing the extreme heterogeneity, ultra-low permeability, and complex pore systems inherent to these reservoirs. This session seeks to showcase cutting-edge techniques and integrated workflows that are pushing the boundaries of petrophysical analysis.
We invite submissions that explore innovative approaches to characterizing the unconventional reservoirs. Topics of interest include, but are not limited to:
Advanced Logging and LWD Technologies: Integration of spectroscopy, nuclear magnetic resonance (NMR), dielectric, and high-resolution imaging logs for enhanced mineralogy, TOC, and porosity assessment.
Multi-Scale Data Integration: Methodologies for reconciling core, log, and seismic data to build accurate and calibrated petrophysical models.
Pore System Characterization: Advances in digital rock physics, mercury injection capillary pressure (MICP), and adsorption isotherms to quantify pore size distribution, surface area, and hydrocarbon-in-place.
Geomechanical Properties: Evaluation of rock brittleness, stress regimes, and natural fractures from logs and core to optimize completion and stimulation design.
Machine Learning and AI Applications: Leveraging data-driven models to predict petrophysical properties, identify sweet spots, and reduce evaluation uncertainty.
Case Studies: Field applications demonstrating the formation evaluation of unconventional reservoirs.

Many regions of the Earth, from crust to core, exhibit anisotropic fabrics which can reveal much about geodynamic processes in the subsurface. These fabrics can exist at a variety of scales, from crystallographic orientations to regional structure alignments. In the past few decades, a tremendous body of multidisciplinary research has been dedicated to characterizing anisotropy in the solid Earth and understanding its geodynamical implications. This has included work in fields such as: (1) geophysics, to make in situ observations and construct models of anisotropic properties at a range of depths; (2) mineral physics, to explain the cause of some of these observations; and (3) numerical modelling, to relate the inferred fabrics to regional stress and flow regimes and, thus, geodynamic processes in the Earth. The study of anisotropy in the Solid Earth encompasses topics so diverse that it often appears fragmented according to regions of interest, e.g., the upper or lower crust, oceanic lithosphere, continental lithosphere, cratons, subduction zones, D'', or the inner core. The aim of this session is to bring together scientists working on different aspects of mechanical anisotropy to provide a comprehensive overview of the field. We encourage contributions from all disciplines of the earth sciences (including mineral physics, seismology, magnetotellurics, geodynamic modelling) focused on mechanical anisotropy at all scales and depths within the Earth.

Seismic attenuation, involving energy loss through scattering and intrinsic absorption, significantly affects seismic wave propagation. As a fundamental property, attenuation plays a central role in subsurface imaging, investigations of Earth’s deep interior, and seismic exploration of planetary bodies. Quantitative analysis of attenuation enables inference of key material properties, such as composition, fluids, or fractures. A comprehensive understanding of attenuation mechanisms also supports robust source characterization and accurate ground-motion modeling, with important implications for hazard assessment and mitigation. In recent decades, advances in theory, numerical modeling, and data analysis have substantially improved attenuation characterization. High-accuracy 3D simulations now allow realistic modeling of wave propagation through complex structures, while advanced inversion techniques better separate scattering from intrinsic absorption. On the observational side, dense seismic arrays and new sensing technologies provide major, yet still underexploited, opportunities to enhance resolution.
This session will bring together experts to present the latest innovations in seismic attenuation research. We welcome theoretical and applied contributions, from work deepening fundamental understanding to studies showcasing practical applications.
Topics of interest include:
• Theoretical advancements that improve understanding of attenuation processes, including scattering and intrinsic absorption.
• Resolve Earth’s internal structure through analysis of attenuation data.
• Numerical simulations of the relevant equations for seismic wave propagation in heterogeneous media and attenuation.
• Applications to the study and characterization of seismic sources.
• Attenuation studies in seismic hazard and damage assessment, including ground motion models and the effects of shaking on structures and infrastructure.
• Energy dispersion from geological heterogeneities, such as faults, fractures, and variations in rock properties.
• Attenuation as an indicator of energy conversion into heat, with applications to geothermal exploration and volcanic hazard assessment.
• Tomographic imaging that integrates attenuation, scattering, and absorption to investigate Earth’s structure from crust to core.
• Planetary science investigations that use seismic attenuation to probe the internal structure and dynamics of other planetary bodies.

Understanding rock deformation requires zooming into the finest details of mineral fabrics down to the nanoscale. Electron and X-ray microscopy performed with laboratory instruments or synchrotrons provides a wide range of imaging techniques in real space (e.g., micro-tomography, X-ray fluorescence microscopy, backscattered- and secondary-electron microscopy, ptychography) and reciprocal space (electron-backscatter diffraction, transmission micro-XRD, small-angle X-ray scattering). This session welcomes studies that use these cutting-edge analytical techniques to investigate strain localization, fluid–rock/mineral interactions, and the links between nano(geo)sciences- to regional-scale deformation across the Earth’s crust. We particularly encourage contributions that integrate such high-resolution datasets with natural observations, experimental techniques and numerical modelling.

Fracture systems are fundamental structural features controlling the mechanical, hydraulic, and geochemical behaviour of rock masses. Their influence ranges from the stability of natural and engineered slopes to fluid migration processes.
This session aims to bring together researchers from different fields to explore and compare methodologies for investigating fractured rock masses, emphasising the value of integrated multi-scale (from grain-scale microcracks to meso-scale fracture networks, up to tectonic-scale systems) and multidisciplinary approaches.
We welcome contributions across a broad geological and process-based context, linking observations and methods from field-based surveys, outcrop characterisation, laboratory testing, microstructural analysis, numerical and analogue modelling, remote sensing, and geophysical imaging. Applications to natural hazards (e.g., rockfalls, landslides), energy and resource exploration, fluid transport and storage, structural geology and tectonics, are particularly encouraged. By bringing together structural geology, rock mechanics, and engineering geology, the session aims to foster a constructive and stimulating discussion on fractures across scales and disciplines, addressing both scientific and practical challenges.

Every year brings new observations about earthquakes with a level of detail never reached before. In parallel, observational and computational methods keep improving significantly in seismology, geodesy, and in paleoseismology-geomorphology. Hence, on one hand, the number of earthquakes with well-documented rupture processes and deformation patterns is increasing. On the other hand, the number of studies documenting long time series of past earthquakes, including quantification of past deformation, has also increased. In parallel, the modeling community working on rupture dynamics, including earthquake cycle, is also making significant progress. Thus, this session is the opportunity to bring together these different contributions to foster further collaboration between the different groups all focusing on the same objective of integrating earthquake processes into the earthquake cycle framework. In this session, we welcome contributions documenting earthquake ruptures and processes, both for ancient events or more recent ones, such as the 2023 Turkey sequence, the 2025 Myanmar earthquake, or the 2025 Kamchatka M 8.8 earthquake, from seismological, geodetic, or paleoseismological perspectives. Work combining different approaches is particularly welcome, as are contributions documenting deformation during pre-, post-, or interseismic periods, which are highly relevant to understanding earthquake cycles. Finally, we seek contributions looking at the earthquake cycle from the modeling perspective, both numerical or analogue, especially including approaches that mix data and modeling.

Fluid-rock interactions play a pivotal role in shaping crustal dynamics and influencing subsurface engineering processes. From the shallow sedimentary rocks down to the deep magmatic and metamorphic rocks, fluids govern aspects such as deformation localization, earthquake genesis, and the emergence of metamorphic reactions and rheological weakening. In most cases, there is a dynamic feedback between fluids, deformation and metamorphism at all scales. Fluids are critical not only for creating robust models of the solid Earth but also for advancing subsurface engineering endeavors like geothermal energy recovery, hydrogen storage and extraction as well as permanent carbon storage.
As we navigate through the ongoing energy transition, enhancing these interactions for maximum geo-resource efficacy is a vital priority. The legacy inscribed within rock records paints a vivid picture of intricate interplay between mineral reactions, fluid flow and deformation—testaments to the often-intense nature of fluid-rock interactions.
This session aims to draw the current picture of the advances and challenges, whether conceptual, methodological, or experimental when considering the role of fluid-rock interactions. We invite contributions that utilize an array of methodologies, ranging from natural observations, microstructural assessments, and geochemical analyses to rock mechanics, all intertwined with modelling techniques. This modelling can span from ab initio simulations to continuum scale simulations, ensuring a comprehensive exploration of fluid-rock/mineral interactions. Contributions that harness the power of artificial intelligence and its subsets are particularly encouraged.

Tectonic faults accommodate plate motion through a spectrum of seismic and aseismic slip that spans a wide range of spatial and temporal scales. Understanding the mechanics and interplay between these deformation modes is central to seismotectonics, as it directly influences the seismic hazard assessment. Fluids play a key role by modulating effective stress and interacting with the evolving permeability and porosity of fault zones. Such hydro-mechanical and chemical feedbacks can promote transitions between stable and unstable slip, influencing earthquake nucleation and arrest as well as the occurrence of slow fault slip phenomena. Advancing our understanding of these processes is essential for constraining the physical conditions that control fault slip behaviors. We invite contributions from observational, experimental, geological, and theoretical studies that explore the diversity and interplay among seismic and aseismic slip phenomena in various tectonic environments. Key questions include: (1) How do fluids, fault properties, and loading conditions shape the distribution of seismic versus aseismic slip? (2) Can the same fault patches host different slip behaviors over time? (3) What systematic spatial or temporal relations exist between aseismic and seismic slip?

Fluids play a critical role in the physical and chemical evolution of the Earth’s crust. They control heat and mass transfer, drive mineral reactions, and have a strong influence on deformation processes. The movement and interaction of aqueous geofluids with rocks in the upper crust are therefore fundamental for processes such as critical raw material mineralisation and the development of geothermal systems. Understanding fluid flow drivers, pathways, and fluid–rock interactions requires approaches that can bridge spatial and temporal scales, from tectonic plates down to individual grains.

We invite to this session all contributions that address fluid flow and fluid–rock interaction in especial those that bridge scales, explore the dynamics of the systems and apply new numerical, experimental, or analytical techniques that improve our ability to understand fluid flow in the Earth’s crust.

Fault systems accommodate deformation through a wide and complex spectrum of slip behaviors, ranging from aseismic creep and episodic slow-slip events to earthquakes. Field and laboratory observations, and seismological and geodetic data along with numerical and analogue modelling show that slip behavior of faults is governed by the interplay of multiple factors acting over a wide range of spatial (from nanometers to kilometers) and temporal (from milliseconds to million years) scales. These factors include tectonic setting, interactions between fault network patterns, structural and geometrical complexity, mechanical and rheological heterogeneities, slip history, fluid pressure and chemistry, and temperature. Despite significant advances, how these interconnected factors collectively control the deformation partitioning within fault systems and the resulting seismic or aseismic behavior of individual fault segments and patches remains a fundamental and unresolved challenge, with major implications for understanding the seismic cycle. This session invites contributions that investigate how fault zones and fault systems accommodate deformation using multidisciplinary and multiscale approaches. We particularly encourage studies based on field and microstructural analyses of exhumed faults, laboratory experiments, geochemical characterization of fluids, seismological and geodetic observations of active faults, and numerical and analogue modelling. Our aim is to foster discussion on fault geometrical complexity and slip behavior, from the scale of entire fault systems down to the physico-chemical processes controlling local fault properties, with implications for understanding complex earthquake sequences and improving seismic hazard assessment in seismically active regions.

Numerous cases of induced/triggered seismicity have been reported in the last decades, resulting either directly or indirectly from injection/extraction activity related to geo-resources exploration and exploitation. Induced earthquakes felt by populations often negatively affect public perception of geo-energies, and may lead to the cancellation of important projects. Furthermore, large earthquakes can jeopardize wellbore stability and damage (surface) infrastructure. Thus, monitoring and modelling processes leading to fault slip, either seismic or aseismic, are critical to developing effective and reliable forecasting methodologies during deep underground exploitation. The complex interaction between injected/withdrawn fluids, subsurface geology, stress interactions, and resulting fault slip requires an interdisciplinary approach to understand the triggering mechanisms, and may require taking coupled thermo-hydro-mechanical-chemical processes into account.

In this session, we invite contributions from research aimed at investigating the interaction of the above processes during exploitation of underground resources, including hydrocarbon extraction, wastewater disposal, geothermal energy exploitation, hydraulic fracturing, gas storage and production, mining, and reservoir impoundment for hydro-energy. We particularly encourage novel contributions based on laboratory and underground near-fault experiments, numerical modelling, the spatiotemporal relationship between seismic properties, injection/ withdrawal parameters, and/or geology, and fieldwork. Contributions covering both theoretical and experimental aspects of induced and triggered seismicity at multiple spatial and temporal scales are welcome.

Naturally fractured reservoirs and faulted rock masses govern fluid flow, mechanical behaviour and long-term performance across a wide range of subsurface applications, including hydrogeology, geothermal energy, hydrocarbons, nuclear waste disposal and CO₂ storage. This joint session brings together contributions that advance our understanding of fracture and fault systems, hydraulic and mechanical properties, and complex interactions between fluids, stresses and evolving discontinuities.

Fractures and faults can modify bulk rock properties by orders of magnitude, impose strong anisotropy, and form primary conduits for fluid flow and transport. Their behaviour is inherently nonlinear and highly sensitive to fluid-rock interactions, which can change transmissibility over time. These dynamic processes influence reservoir productivity, containment performance, induced seismicity potential and operational risks in geoenergy and storage projects.

Representing and modelling these systems remains a challenging task due to their structural complexity, spatial variability in physical properties, and multi-scale deformation processes. Integrating field observations, monitoring data, laboratory measurements and numerical modelling is essential to capture fracture-network evolution and fluid-driven changes. We especially welcome contributions on faults and fractures addressing:

• Structural characterisation using deterministic or stochastic approaches
• Numerical methods for continuous, discontinuous (DFN), or hybrid media
• Simulation of coupled or individual (THMC) processes
• Deterministic and stochastic inversion techniques for model calibration and uncertainty reduction
• Interdisciplinary studies linking deformation processes, transmissibility changes and fluid-rock interactions
• Applications to geothermal, groundwater, petroleum, CO₂ storage, waste repositories and other low-carbon subsurface technologies

We encourage submissions spanning multiple scales from laboratory experiments to reservoir-scale analyses and studies that bridge the gap between observation, measurement and simulation. Research integrating diverse methods to improve predictive understanding of fault and fracture behaviour in subsurface energy systems is particularly welcome, and early-career scientists are warmly encouraged to contribute.

Low-Earth-orbit (LEO) satellites provide unique opportunities to characterize the Earth's magnetic field, ionospheric currents and plasma parameters, and thermosphere density and winds across a wide spectrum of time and spatial scales, and for a large range of solar and geomagnetic activities. At the forefront of this advance are the three ESA Earth Explorer Swarm satellites, which have been providing high-accuracy measurements of the Earth's magnetic field, electric field, plasma parameters, precise-orbit determination, and accelerometer observations since their launch in November 2013. They have proven very valuable for studying the near-Earth magnetic field and the coupled ionospheric-thermospheric environment, and enabled the development and implementation of advanced models and operational space weather services. The scientific potential of the polar-orbiting Swarm satellites is today augmented by newly available data, especially those collected by the low-inclination Macau Science Satellite 1 and CSES satellites.
In addition, the ESA Scout NanoMagSat constellation, consisting of one near-polar and two 60° inclination satellites, is scheduled to launch near the end of 2027, with full operation planned for 2028. It will acquire high-accuracy magnetic vector and scalar data, electron density, and electron temperature
data, navigation data, and collect ionospheric radio-occultation profiles. All these data are also complemented by increasingly available platform-magnetometer data, such as from the CryoSat-2, GRACE, GRACE-FO, GOCE, and E-POP satellites. The new abundance of satellite data provides unprecedented space-time data coverage at LEO satellite altitudes, opening the way for new scientific opportunities.

The panoramic view of the Sun-Earth system encompasses Earth's outer core, the primary source of the geomagnetic field, the upper atmosphere, and the magnetosphere, which shields against high-energy radiation and significantly impacts human microwave communications, and coronal mass ejection, shaping Earth's electromagnetic environment by propagating through interplanetary space.

Rock magnetism involves a wide range of laboratory and computational methods with applications in biological, geological, environmental, material and planetary sciences. Recent advances in imaging, computational modelling and experimental techniques now allow for an unprecedented level of detailed characterisation of magnetic minerals in both terrestrial and extraterrestrial materials. New mineral magnetic datasets potentially inform understanding of palaeomagnetic recording, (palaeo)climatic variability, biomineralization, planet formation and diverse modern environmental and anthropogenic processes.
