Climate Driven Water Table Changes and Their Influence on Liquefaction Response of Integral Bridges

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Integral abutment bridges (IABs) eliminate bearings and joints but transfer seismic demand directly into the surrounding soil, making their response highly sensitive to groundwater conditions and soil–structure interaction. This study presents a 60 g centrifuge testing programme on single‐span IABs designed to isolate the influence of water ...

Seismic Fragility of Gravity and Semi‐Gravity Retaining Walls and Its Impact on the Functionality Loss of Road Infrastructures

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Retaining walls are key geotechnical components of road infrastructure, whose seismic performance directly affects the resilience of transportation networks. Despite their importance, seismic fragility models for retaining walls available in the literature refer only to specific case studies.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin

open access: yesGeological Journal, EarlyView.
Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.
