Field Test and Numerical Research of Blast-Induced Liquefaction in Calcareous Sand

Shock and Vibration
In recent years, the engineering losses caused by liquefaction of calcareous sand foundations have gradually increased. However, there are relatively few studies on the mechanism of blast-induced liquefaction in saturated calcareous sand foundations.

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Experimental Study on Mechanism of Wave-Induced Liquefaction of Sand-Clay Seabed

Journal of Marine Science and Engineering, 2020
In this study, a series of laboratory experiments for the response of wave induced clay-sand seabed were carried out to clarify the mechanism of liquefaction of clayey seabed. The experiments were conducted in an 80 m long wave flume.

Bubble‐Mediated Intensification of Biomass‐Based Oil Conversion: Bubble Dynamics, Control Strategies and Equipment

Carbon and Hydrogen, Volume 28, Issue 3, Page 320-339, September 2026.
Focus on the bubble interface transfer behavior during the conversion process of biomass‐based oil, and mainly review the bubble dynamic characteristics in the gas‐solid/gas‐liquid reaction processes under extreme conditions during the conversion process.

Multi‐Hazard Shaking‐Tsunami Fatality Risk Estimation for Coastal Communities

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2618-2633, September 2026.
ABSTRACT This study develops a multi‐hazard fatality risk model for a coastal community (Tofino) on Vancouver Island, Canada, subjected to earthquake‐tsunami threats from the Cascadia subduction megathrust events. The model incorporates variable population distributions and uncertain fatality rate models, in addition to other key model components, such

Cyclic liquefaction behavior of silty sand considering initial static shear effect: a DEM investigation

Yantu gongcheng xuebao
To gain more insights into the microscopic mechanism of the liquefaction behavior, the particle flow program PFC3D is used to simulate the liquefaction process of silty sands under undrained cyclic loading.

Uneven Impacts of Seawall Heightening on Tsunami Risk Reduction under Rising Sea Levels: Probabilistic Scenarios from the Japan Trench

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2948-2965, September 2026.
ABSTRACT Disasters exacerbated by climate change have prompted adaptation measures, including seawall heightening, which is an effective approach to protecting coastal areas. However, the combined effect of rising sea levels and tsunamis can create a compound coastal hazard, in which long‐term sea level rise amplifies the impact of tsunamis.

USE OF SMALL-SCALE LIQUEFACTION FEATURES TO ASSESS PALEOSEISMICITY: AN EXAMPLE FROM THE SALINE RIVER FAULT ZONE, SOUTHEAST ARKANSAS, U.S.A.

Frontiers in Earth Science, 2014
Large-scale liquefaction features (e.g., sand blows, lateral-spread fissure vents) that can be recognized on remote-sensing imagery and photography have been of great utility in developing chronologies of paleo-earthquakes.

Overshooting of Hypoplastic Models With Intergranular Strain: Manifestation, Implications and Remedy

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 13, Page 5068-5091, September 2026.
ABSTRACT Intergranular strain extensions of hypoplasticity (IGS, ISA, GIS) are widely used to model small‐strain and cyclic soil behaviour. However, recent studies and our own simulations reveal that these models can exhibit stress overshooting not only under repeated small loading cycles but also during monotonic loading.
