From Highlands to Henge: Refining the Provenance and Transport Pathways of Stonehenge's Altar Stone

Journal of Quaternary Science, EarlyView.
ABSTRACT The Altar Stone, the 6000 kg central sandstone megalith at Stonehenge in southern England, is suggested to have originated from the Orcadian Basin in northeast Scotland, some 700 km away. However, its source location within this large basin remains unresolved and its mode of transport uncertain.

Estimating the critical angle of top near‐surface layers on the Moon

Near Surface Geophysics, EarlyView.
Abstract Near‐surface characterization of the lunar subsurface is essential for future exploration and infrastructure development, particularly for the construction of underground habitats that provide protection against radiation and micrometeorites. However, conventional seismic approaches for estimating subsurface properties typically rely on prior ...

Using synthetic models to understand the detecting ability of ground‐penetrating radar for water‐conducting structures in the bedrock of formerly glaciated site

Near Surface Geophysics, EarlyView.
Abstract Utilizing synthetic models for the interpretation of ground‐penetrating radar (GPR) profiles can aid in the detection of hydrogeological structures by identifying their signatures. In this study, finite difference (FD) forward modelling was used to understand the detection ability of 50 MHz GPR for (1) the quaternary deposit–bedrock contact ...

Engineering geology and geotechnical study of Drynoch Landslide, British Columbia

, 1980
Drynoch landslide, a large earthflow along Thompson River in southwestern British Columbia, has been moving slowly for many hundreds of years and for the past one hundred years has disrupted transportation facilities which cross its toe. The slide has been noted and studied during the past century by numerous scientists and engineers.

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

Sustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

Post‐earthquake field assessment and damage correlation of elevated reinforced concrete water tanks in Kahramanmaras/Elbistan, Türkiye

Structural Concrete, EarlyView.
Abstract This study evaluates the seismic performance of elevated reinforced concrete (RC) water tanks in the Elbistan region following the February 6, 2023 Kahramanmaras–Elbistan earthquakes. Field investigations, visual damage surveys, non‐destructive testing (ultrasonic pulse velocity—UPV), concrete compressive strength measurements, peak ground ...

Simulation Method and Application of Non-Stationary Random Fields for Deeply Dependent Seabed Soil Parameters

Journal of Marine Science and Engineering
The spatial variability of geotechnical parameters, such as soil shear wave velocity (Vs), exhibits significant nonlinearity and non-stationarity with respect to depth (h) due to the influence of overlying stress.

Of cables and threads

American Ethnologist, EarlyView.
Abstract Over the past two decades, gondola lifts have become central to interventions in urban Latin America's auto‐constructed peripheries. As cable car urbanism reshapes the city's edge, it raises fundamental questions about the notion of the “urban fabric” as a sociomaterial practice, an epistemology, and a site of politics.

Appraisal of lacustrine aquifer’s groundwater potentiality and its hydrogeological modelling in southeastern Peshawar, Pakistan: implications for environmental geology, and geotechnical engineering

International Journal of Geo-Engineering
The Peshawar Basin is a part of the lower Himalayas that contains an enormous amount of groundwater storage. The evaluation of groundwater potential in the southern Peshawar district was done using well logging, lithostratigraphic properties, and ...
