Tidal Response of Seismic Wave Velocity at Shallow Crust in Japan
Geophysical Research Letters, 2023 Microcracks in geomaterials cause variations in the elastic moduli under applied strain, thereby creating seismic wave velocity variations. These are crucial for understanding the dynamic processes of the crust, such as fault‐zone damage, healing, and ...

Terra Nova, Volume 38, Issue 3, Page 163-172, June 2026.ABSTRACT In this study, we examine the relationship between Brune stress drop and fault slip where the stress drop is estimated using the Empirical Green's Function (EGF) method and slip distribution is derived from seismic and geodetic data inversion.

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Drained and cultivated grasslands on peat soils behave as a significant source of greenhouse gasses by oxidation. However, the lack of empirical estimates of carbon losses from peatlands with adequate spatial and temporal resolution has forced researchers to rely on process‐based model approximations to make quantitative, regional‐ or national‐

Does Geocentric Sea‐Level Rise in the Maritime Continent Reveal a Tectonic Fingerprint?
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract The islands of the Maritime Continent are highly vulnerable to sea‐level rise driven by barystatic, sterodynamic, and vertical land motion (VLM) processes. While tectonics is known to affect relative sea‐level through VLM, its influence on long‐term geocentric sea level (GSL) through crustal deformation and gravity field perturbations remains ...

Development of a State-Wide Velocity Profile in Oklahoma Using Ambient Noise Seismic Tomography [PDF]
, 2018 Earthquakes have been a growing concern in the state of Oklahoma in the last several years and as a result, prediction of the ground motion, understanding of subsurface geological structure, and the estimation of accurate earthquake location are of ...

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Changes in seismic properties can help assess slope damage, which is influenced by external factors such as temperature, relative humidity, rainfall, air pressure, and local seismicity. However, the contributions of these factors, and how the dominant factor modulates transient and seasonal seismic velocity changes (δv/v $\delta v/v$), remain ...

Measuring and modelling deformation during the Dabbahu (Afar) rifting episode [PDF]
, 2010 In September 2005, a 60-km-long dyke intruded the Dabbahu segment of the Nubia-Arabia plate boundary (Afar, Ethiopia), marking the beginning of an ongoing rifting episode.

Seismic interferometry with antipodal station pairs [PDF]
Geophysical Research Letters, 2013 In this study, we analyze continuous data from all Global Seismographic Network stations between year 2000 and 2009 and demonstrate that several body wave phases (e.g., PP, PcPPKP, SKSP, and PPS) propagating between nearly antipodal station pairs can be clearly observed without array stacking using the noise/coda cross‐correlation method.
