The Effect of Hydraulic Fracturing on the 2021 Ms 6.0 Luxian Earthquake as Revealed by Deformation and Numerical Simulations

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract This study investigates whether hydraulic fracturing contributed to the 2021 Ms 6.0 Luxian earthquake in the Sichuan Basin. Time‐series InSAR analysis of multi‐temporal Sentinel‐1 data reveals coseismic deformation associated with the 2021 Luxian earthquake and localized uplift near hydraulic fracturing platforms.

Seismicity Precursors and Their Practical Account

open access: yesGeosciences
Earthquakes (EQs) are the most unpredictable and damaging natural disasters. Over the last hundred years, the scientific community has been engaged in an intense endeavor to attain a confident and secure method of seismic activity forecasting.

Shallow Modeling and Site‐Amplification From Telecommunications Fibers in Istanbul

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract We use pre‐existing fiber‐optic telecommunications fibers in Istanbul, Türkiye, to generate a seismic velocity model of the subsurface down to 100 m depth, and estimate site‐amplification in the region. We collect ambient noise, predominantly from urban traffic, along the 8 km segment fiber, extract Rayleigh wave dispersion curves, and use a ...

Geophysics: A Very Short Introduction

open access: yes, 2018
Geophysics is the physics of the Earth. It encompasses areas such as seismology, plate tectonics, gravity, and the Earth’s magnetic field, all of which give clues to both the structure and the working of the Earth.

Hybrid XGBoost-RF-MLP model and PSO optimization for performance and emissions of CI engine using waste cooking biodiesel blends

open access: yesScientific Reports
Transesterification was used to create methyl ester from waste cooking oil (WCO). Diesel oil and biodiesel blends in 25, 50, 75, and 100% were developed and authorized by ASTM.

Lithosphere‐Asthenosphere Interactions Across the Indo‐Burma Subduction Zone From Sp Receiver Functions

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Cenozoic convergence between the Indian and Asian plates has driven large‐scale mantle convection that interacts with both plates. Understanding this convergence benefits from clear imaging of the lithosphere‐asthenosphere boundary (LAB).

Elastic waves in reflection seismology

open access: yes, 1991
This set of lecture notes is designed to give an introduction to the role which elastic wave phenomena play in exploration seismology. As a result the emphasis is somewhat different from general texts on seismic wave theory (e.g.
