From Risk Perception to Action: The Behavioral Forces Shaping Disaster Preparedness

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract The study examines the behavioral forces spanning cognitive, social, and environmental determinants that transform disaster risk perception into tangible preparedness actions. The case study at hand focuses on Bucharest, the European capital with the highest seismic risk.

Teleseismic S‐Wave Coda Autocorrelation and vp/vs ${v}_{p}/{v}_{s}$ Distribution Over the Antarctic Ice Sheet

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Accurate characterization of the compressional to shear (P‐to‐S) wave‐speed ratio (vp/vs ${v}_{p}/{v}_{s}$) within the Antarctic Ice Sheet (AIS) is crucial for understanding its internal structure, mechanical stability, and vulnerability to a changing climate.

Frequency dependent attenuation of seismic waves for Delhi and surrounding area, India

Annals of Geophysics, 2015
The attenuation properties of Delhi & surrounding region have been investigated using 62 local earthquakes recorded at nine stations. The frequency dependent quality factors Qa (using P-waves) and Qb (using S-waves) have been determined using the ...

Thermochemical Controls on the X, 410, and 660 Discontinuities in the Central Mediterranean

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The mantle beneath the Central Mediterranean is thermally and compositionally heterogeneous, as indicated by fragmented and locally stagnant slabs in tomographic images and HIMU‐like anorogenic magmatism. Mantle discontinuities are sensitive to both temperature and composition, and thus provide a way to quantify these heterogeneities.

Building damages in Deyang city by the 2008 Wenchuan earthquake

Geodesy and Geodynamics, 2011
The Ms8.0 Wenchuan earthquake in 2008 caused huge casualties, economic losses, and building damages, which are analyzed. The results show that damages of houses designed according to the current seismic code were significantly smaller than those without ...

Transfer Learning and Benchmarking for Induced Seismic Event Detection: Insights From Oklahoma

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Machine learning models for microseismicity detection are often limited by the scarcity of large and high‐quality labeled data sets in many regions. To address this need, we introduce the Oklahoma Labeled AI Dataset (OKLAD), a manually curated data set compiled by the Oklahoma Geological Survey (OGS).

Anomalously strong observations of PKiKP/PcP amplitude ratios on a global scale [PDF]

, 2015
The inner core boundary marks the phase transition between the solid inner core and the fluid outer core. As the site of inner core solidification, the boundary provides insight into the processes generating the seismic structures of the inner core.

Ionospheric disturbances around the time of the Ms7.0 Lushan earthquake

Geodesy and Geodynamics, 2013
Variations of Vertical Total Electron Content (VTEC) in the ionosphere are investigated around the time of the Ms7. 0 Lushan earthquake. A time-series analysis shows an anomalous VTEC increase 15 days before as well as some anomalous VTEC decreases 5 ...

Massive Rocky Planets May Suppress Deep Melting

AGU Advances, Volume 7, Issue 4, August 2026.
Abstract Melting properties of silicates are critical to understanding the thermal evolution of rocky planetary interiors. In the deep mantles of massive rocky planets, post‐post‐spinel Mg2SiO4 ${\text{Mg}}_{2}{\text{SiO}}_{4}$ is potentially one of the most abundant mineral phases, yet its melting behavior remains unconstrained. Here, we determine the

Investigating Meter‐Scale Wavefield Complexity and Amplification at the Basin Edge With a Fiber‐Optic Array

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Edges of sedimentary basins generate complex seismic wavefield effects and localized amplification. Characterizing these effects and incorporating them into hazard models is difficult because tomographic models are often smooth and wavefield observations are often aliased.
