Correcting exponentiality test for binned earthquake magnitudes

Seismica
Above the magnitude of completeness - the minimum threshold for which a 100% detection rate is assumed - earthquake magnitudes are typically modeled as a continuous exponential distribution.

Complex Shear‐Wave Splitting Behavior in the Northern Andes and Possible Implications for Mantle Flow Around the Caldas Tear

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract We investigate shear‐wave splitting of SKS and SKKS phases from teleseismic earthquakes to study the anisotropic structure of the lithosphere and upper mantle beneath the Colombian Andes. This area is shaped by complex interactions between the subducting Nazca and Caribbean plates beneath the South American plate. A recent broadband deployment

Multi‐Scale Rate‐ and Roughness‐Dependent Frictional Constitutive Law and Dynamic Earthquake Sequence Simulation

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract The physical mechanisms that govern the multi‐scale source properties of earthquakes, such as fracture energy scaling, where the dynamic energy dissipation of earthquakes scales with fault slip, remain debatable. We introduced the rate‐ and roughness‐dependent friction (RRF) law which accounts for the multi‐scale roughness evolution of the ...

Predictive Models for Postfire Debris Flow Initiation in the Southwest USA

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Postfire debris flows pose a threat to life and infrastructure and significantly contribute to sediment supply in upland channels, thereby impacting water quality, stream habitats, and landscape evolution. Models designed to assess postfire debris‐flow likelihood at the watershed scale in response to design or forecast rainstorms are ...

Reactivation Mechanism of Dormant Earthflows: Insights From the San Benedetto Landslide (Northern Apennines, Italy)

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Earthflows are landslides in fine‐grained materials that alternate long dormant phases of very slow movement with short paroxysmal stages of rapid motion. These rapid phases are highly destructive, often causing severe damage to buildings and infrastructure.

A Deep Learning Framework for Peak Ground Velocity Prediction Using Multi‐Station Velocity Waveforms: The Taiwan Transformer Shaking Alert Model (TT‐SAM)

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract This study proposes a deep‐learning–based regional earthquake early warning model, the Taiwan Transformer Shaking Alert Model (TT‐SAM). The model adopts peak ground velocity (PGV) as its primary ground shaking prediction unit, aiming to better reflect actual structural damage and thereby enhance the practical utility and accuracy of the ...

Investigation of the Spatial Clustering Properties of Seismic Time Series: A Comparative Study from Shallow to Intermediate-Depth Earthquakes

Complexity, 2018
In this paper, a size-independent modification of the general detrended fluctuation analysis (DFA) method is introduced. With this modified DFA, seismic time series (m≥4.5) pertaining to most seismically active regions of the world from the year 1972 up ...

Redistribution of Basal Forces and Shielding Model for Seismic Signals of Debris Flows Over Loose Thin‐Layer Sediments

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Debris flows over riverbeds generate intense basal force fluctuations that radiate seismic signals, offering a key tool for remotely monitoring their dynamics. In steep, highly erosive mountainous channels, bedrock is often covered by a thin layer of loose sediments, which significantly reduce seismic energy.

Unsupervised Deep Representation Learning for Infrasound Phase Identification

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Infrasound phase identification is challenging because atmospheric variability strongly influences signal propagation on short timescales that are not resolved by standard atmospheric models. While traditional approaches rely on propagation modeling and array‐derived parameters, recent work suggests that waveform structure itself encodes ...
