Numerical and Experimental Seismic Characterization of Byblos Site in Lebanon

open access: yes
Geological and topographic site effects lead to variations in the spatial distribution of ground motion during large earthquakes. Despite the impact of such phenomena, they remain poorly understood.

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

open access: yesJournal 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.

Application of different earthquake-induced landslide hazard assessment models on the 2022 Ms 6.8 luding earthquake

open access: yesFrontiers in Earth Science
Following the earthquake, prompt evaluation of the distribution of coseismic landslides and estimation of potential disaster losses are crucial for emergency response and resettlement planning.

Disrupting the herd: Recreational boating alters group dispersion within beluga whale herds

open access: yesThe Journal of Wildlife Management, EarlyView.
Recreational boating in beluga habitat remains poorly documented. Using land‐based observations in the Saguenay Fjord (Quebec, Canada), we show that increasing recreational boat numbers are associated with a higher probability of changes in beluga herd dispersion, suggesting behavioral disturbance and the need to integrate recreational boating into ...

Intrinsic and scattering attenuations of the Sichuan-Yunnan region in China from S coda wavesKey points

open access: yesEarthquake Science
Seismic attenuation is a fundamental property of the Earth's media. Attenuation structure for the complicated geological structures with strong seismicity in the Sichuan-Yunnan region is poorly studied. In this study, we collected 108,399 waveforms of 11,

A novel approach for in situ benthic habitat characterization

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Habitat heterogeneity is a key driver of temporal and spatial variability of subtidal marine benthic biodiversity. However, this makes it a challenging environment in which to measure and quantify the factors driving biodiversity in a consistent manner.

Potential laharic risks associated with the Millennium Eruption products of Tianchi volcano, NE China

open access: yesNatural Hazards Research
Tianchi volcano has experienced continuous eruptions, including the Millennium Eruption (ME) event that produced a volcanic explosivity index of 6–7 in approximately 946 CE, which is among the most hazardous eruptions in human history.

A Coupled Extended Finite Element–Cohesive Zone Model for Hydraulic Fracture Propagation Under Poroelastic Effects Across Different Propagation Regimes

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Numerical simulation of hydraulic fracturing remains challenging due to the strong coupling between geomechanics and fluid flow when modelling multiple physical mechanisms of rock deformation, fracture evolution and fluid leak‐off. This study develops a coupled hydraulic fracture propagation framework that combines the extended finite element ...

Geographic information systems (Gis) and natural hazards

open access: yes, 2013
Understanding the natural hazards is one of the most important issues in the earth science field. This is useful not only for analyzing a natural process from the scientific point of view, but also for understanding the link between the human system and ...
