QuakeML: status of the XML-based seismological data exchange format

Annals of Geophysics, 2011
QuakeML is an XML-based data exchange standard for seismology that is in its fourth year of active community-driven development. Its development was motivated by the need to consolidate existing data formats for applications in statistical seismology, as

First‐Principles Investigation of the Structural, Electronic, Optical, Elastic, and Thermal Properties of Defect Diamond‐Like Hg3P2S8

Advanced Physics Research, Volume 5, Issue 8, August 2026.
The defect diamond‐like material Hg3P2S8 (HPS) is systematically investigated using first‐principles methods to reveal the interplay between highly distorted HgS4 and rigid PS4 units. The HPS material exhibits a strong anisotropic second‐harmonic generation (SHG) response, favorable optical properties, and low thermal conductivity, highlighting its ...

Ensemble Kalman filter for the reconstruction of the Earth's mantle circulation [PDF]

Nonlinear Processes in Geophysics, 2018
Recent advances in mantle convection modeling led to the release of a new generation of convection codes, able to self-consistently generate plate-like tectonics at their surface.

Regional Earthquake Ground Motion Simulations for Southern California With EQSIM: Insights From the 2008 Chino Hills, 2024 Highland Park, and 2021 Carson Earthquakes

Earthquake Spectra, Volume 42, Issue 3, August 2026.
This study presents physics‐based, 3D simulations using the EQSIM framework for several earthquakes in the Los Angeles region. The primary objective was to assess the ability of deterministic physics‐based ground motion simulations to reproduce the observed motions from historical events.

Validation of ShakeMaps Created From Global Navigation Satellite System (GNSS) Velocities

Earthquake Spectra, Volume 42, Issue 3, August 2026.
Ground velocity observations generated through a time difference of Global Navigation Satellite Systems (GNSS) phase observables and orbits have been shown to be comparable to seismic recordings without clipping during intense ground motions. Computing GNSS velocities is also computationally scalable and increases the density of ground motion ...

Partitioning Site Amplification and κ0 in Earthquake Recordings

Earthquake Spectra, Volume 42, Issue 3, August 2026.
This study explores site amplification and spectral decay (κ0) estimates, focusing on the challenge of separating the two in observed Fourier amplitude spectra (FAS). We apply two general approaches: a Bayesian broadband inversion for simultaneous estimation of site amplification and κ0, and slope‐based methods for direct κ0 estimation from the ...

Can Domain‐Informed Design Improve Neural Spatio‐Temporal Point Processes for Earthquake Forecasting?

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Statistical earthquake forecasting models, such as the Epidemic‐type Aftershock Sequence (ETAS), embed decades of empirical knowledge and assumptions about earthquake triggering, clustering, and catalog completeness. In contrast, neural spatio‐temporal point process (STPP) models often treat seismicity as generic spatiotemporal data without ...

The role of radiation damping in the modeling of repeated earthquake events

Annals of Geophysics, 2013
We have investigated the role of the radiation damping term (RDT) on repeated earthquake ruptures by modeling the faulting process through a single one-dimensional analog fault system governed by different constitutive laws.
