Integrated Geophysical Imaging Reveals the Origin and Pathways of Mantle‐Derived CO2 Beneath the Tangra Yumco Rift, Central Tibet

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Tangra Yumco Rift (TYR) in central Tibet is a key window for crust–mantle interactions during extension. We performed high‐resolution crust‐mantle imaging using receiver function analysis, 1‐D nonlinear S‐wave velocity inversion, and tomoDD tomography, revealing a vertical Crust–Mantle Degassing System (CMDS) bounded by the Zhala (ZF) and ...

Passive seismic data processing methods to identify contrast intrasalt interlayers in the geological section of the Astrakhan Arch

Georesursy
The article examines the problem of processing microseismic noise (MN) to identify and evaluate occurrence depth of contrasting geological objects – intersalt interlayers with a potentially high formation pressure.

Listening to Bryde's Whales With an Island Seismometer: Low‐Frequency Call Detection and Seasonal Patterns Revealed by Deep Learning

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Bryde's whales form a major coastal aggregation in the Beibu Gulf, China. Using 1 year of continuous island‐based seismic recordings from Xieyang Island, we established a large labeled data set of coastal Bryde's whale calls with more than 1.7 million samples.

Quantification of the Eocene–Oligocene transition in the Zagros Foreland Basin: Palaeogeographic control on sequence architecture and tectonic signal preservation

The Depositional Record, Volume 12, Issue 3, June 2026.
New bio‐sequence framework for the Eocene–Oligocene transition in Zagros. Geochemical data validate basin depth control on SB1 vs. SB2 boundaries. SEM‐EDS analyses confirm subaerial exposure versus continuous deposition. Sensitivity analysis quantifies sub‐10% uncertainty in stratigraphic interpretations. Resolves the Pyrenean orogeny's variable impact

Methodological procedure for applying geophysics to geotechnical studies in Luanda City, Angola

Minería y Geología, 2018
The use of the surface wave’s analysis in its passive and active variants was jointly assessed by the shallow seismic refraction. It allows determining dynamic parameters from the longitudinal and transverse velocities, obtained from seismic methods. For

For the Few, Not the Many: Tracing the Residualist and Compensatory Nature of British Energy Support

Environmental Policy and Governance, Volume 36, Issue 3, Page 529-547, June 2026.
ABSTRACT Drawing on extensive documentary analysis, this article traces the evolution of British energy policy support since World War II. It analyses shifts in policy design through two interpretive lenses: eligibility (residualist vs. universalist) and function (compensatory vs. preventive).

Multiple Scattering Suppression in Heterogeneous Media: High‐Precision Imaging of Sleeve Grouting Defects Based on Elastic Reverse Time Migration

Engineering Reports, Volume 8, Issue 6, June 2026.
This study proposes an elastic wave reverse time migration (RTM) method to suppress multiple scattering noise in heterogeneous concrete. By effectively utilizing scattered wavefields, RTM enables high‐precision, robust imaging of sleeve grouting defects in prefabricated buildings, significantly outperforming traditional algorithms.

Study on the Influence of Slope Static Load on Shallow Lining Support Structure

Energy Science &Engineering, Volume 14, Issue 6, Page 2721-2735, June 2026.
On the basis of the background of the shallow‐buried main adit supported by stone lining, the mechanical model of the supporting structure is constructed, and the stability of the supporting structure is analyzed by using the methods of field investigation, theoretical analysis, and numerical simulation.

An Isotope‐Based Snapshot Reveals the Combined Influence of High‐Elevation Recharge and Local Return Flows on Groundwater Across Guatemala City

Hydrological Processes, Volume 40, Issue 6, June 2026.
Representation (not to scale) of potential high elevation recharge and low elevation return flows within the Guatemala City metropolitan area. ABSTRACT Guatemala City is the most populous urban center in Central America. In this urban center, groundwater extraction within the last 40 years has substantially declined water table levels and accelerated ...

Creating Flood Disasters: Environmental Memory and Adaptation in Aotearoa New Zealand

Kōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 2, June 2026.
This article explores three questions. First, why does New Zealand have widespread flooding hazards? Second, why are these persistent, with little seemingly learned from the memory of earlier events? And third, beyond reiterating conventional solutions, what examples of alternatives or adaptations are being developed in different places?
