Call for Abstracts: AGU 2026 Session on Earthquake Detection and Seismic Hazard
|
|
How can we transform our rapidly growing earthquake catalogs into reliable information about seismic hazards? Our AGU session highlights research that bridges the gap between earthquake detection, seismological characterization, and hazard assessment. We invite contributions that advance the validation, interpretation, and application of earthquake detections to improve our understanding of earthquake source processes and forecasting of seismic hazards and risk.

S015: From Earthquake Detection to Hazard: Advances in Catalogs, Magnitudes, and Seismological Validation
|
- Eric Beaucé — Next-generation earthquake catalogs: Opportunities and challenges for scientific discovery
- Chengping Chai — QuakeMind: An Agentic Platform for Seismological Applications
Recent advances in earthquake detection, including machine learning, template matching, distributed acoustic sensing (DAS), and dense seismic network observations, are rapidly expanding earthquake catalogs. However, translating these developments into reliable seismic hazard and risk assessments requires equally robust seismological characterization, including magnitude estimation, phase picking, velocity models, focal mechanisms, catalog validation, uncertainty quantification, and source parameter measurements.

The session focuses on the processes preceding, accompanying and following dynamic and slow ruptures. Rupture nucleation and propagation in fault zones, volcanoes, glacier systems, and landslides are governed by multiple factors including material properties, in situ stress and fluid pressure conditions, time-dependent deformation and pre-existing heterogeneities or defects. Geophysical and geological observations across fault systems at multiple scales allow to quantitatively characterize the nucleation and propagation of ruptures and to assess the thermo-hydro-mechanical properties of shear zones. At the laboratory scale, new experiments are able to investigate the 3D microstructure evolution of a deforming rock and to quantify the entire strain field. Concurrent numerical modeling efforts assist laboratory observations by unraveling the governing physical processes. Our aim is to integrate field, laboratory, and modeling investigations to address the multi-scale deformation mechanisms before, during and after major slow and fast ruptures Deadline for submission: 5 August 2026 at 23.59 EDT

Call for Abstracts: AGU Session G013 - Recent Advances in SAR and InSAR Processing, Big Data, Analysis, and Earth

Abstracts are due Wednesday August 5th at 11:59 EDT.

Description: InSAR geodetic imaging has become operational, driven by the extensive SAR data archive from Sentinel-1A/B. The SAR archive is expanding with missions such as Sentinel-1C/D (C-band), NISAR (L/S-band), ALOS-2/4 and ROSE-L (L-band), Biomass (P-band), SWOT (Ka-band), and commercial X-band SAR constellations. We invite contributions on opportunities and challenges presented by these advancements, including applications enabled by NISAR. Topics include: (1) processing methods that maximize the value of dense, multi-mission SAR time series across imaging geometries (2) studies of how wavelength, polarization, and geometry affect the accuracy and uncertainty of geodetic and geophysical estimates, including the roles of NISAR's L- and S-band data (3) approaches leveraging big data analysis, deep learning, AI, cloud computing, and analysis-ready products to transition scientific advancements to decision-making applications. (4) novel SAR and InSAR applications, including using closure phase measurements and other emerging observables, especially for missions envisioned beyond NISAR.

AGU26 Session G024 - Transient Deformation and Creep Processes in the Earthquake Cycle
|
We invite you to submit an abstract to our session at AGU this year.
G024 - Transient Deformation and Creep Processes in the Earthquake Cycle
Session Description:Transient deformation and aseismic slip processes play a fundamental role in the earthquake cycle, yet their spatiotemporal characteristics and underlying physics remain incompletely understood. Advances in geodetic techniques, including GNSS, InSAR, and creepmeters, together with seismic and geological observations, have revealed a wide spectrum of transient phenomena such as creep, slow slip events, afterslip, and postseismic relaxation. These aseismic phenomena can occur spontaneously or be triggered or induced by tectonic, environmental, or anthropogenic activities. Aseismic slip is also sometimes accompanied by other faulting processes, such as repeating earthquakes and tremors. This session aims to bring together studies that investigate the spatiotemporal evolution, mechanisms, and implications of transient deformation across diverse tectonic settings. We welcome contributions that utilize geodetic, seismic, and geological data, as well as numerical and analytical modeling and laboratory experiments to better understand the physical processes governing the spectrum of aseismic fault slip behavior.

AGU26 Call for Abstracts- S027: Seismic Imaging from Crust to Core: Understanding Ancient and Contemporary Processes
|
Please consider submitting an abstract to our AGU session, S027: Seismic Imaging from Crust to Core: Understanding Ancient and Contemporary Processes. We invite contributions that image the Earth or other planets at any scale—ranging from the near-surface to planetary interiors—using any method. We also seek contributions that use novel methods or datasets to constrain Earth structure.

Abstract: Seismic imaging is a key tool for understanding subsurface processes, often providing a pivotal lens into tectonic processes in the near-surface and crust as well as planetary-scale dynamics in the mantle and core. Technical advances in methodologies ranging from receiver functions and autocorrelations to earthquake and ambient noise tomography provide key constraints on geologic and tectonic processes in the Earth and other planets. Novel sensing techniques such as large-N nodal arrays, ocean bottom seismometers, and Distributed Acoustic Sensing (DAS) have provided key resolution in areas where traditional seismic sensors are sparse or difficult to install. We invite research on all spatial and temporal scales that uses seismic imaging to study the subsurface. We invite presentations using novel techniques or datasets and research on the application of seismic imaging models to related fields.

Call for Abstracts: AGU Session NH051 - Stress, Strain, and Surge: The Rheology of Natural Hazards
|
Please consider submitting an abstract to the following AGU session:
NH051 - Stress, Strain, and Surge: The Rheology of Natural HazardsThe mechanical behavior of Earth materials represents a unifying theme in both the occurrence and prediction of a wide range of natural hazards including landslides, earthquakes, volcanic eruptions and flank collapse, and sudden glacial acceleration (i.e., surging or complete detachment). We invite submissions that bring perspectives from laboratory, field, and/or numerical approaches to understand the role of rock, sediment, soil, ice, and magma rheology (as well as their mixtures). This session will explore how knowledge of rheology can be used to constrain ambient in situ conditions (e.g. stress, fluid pressure, and subsurface heterogeneity) that set the stage for failure, as well the deformation processes and dynamics that underpin hazards.
