Numerical Investigation of Bored Tunnelling Effects on Pile‐Supported Superstructures
ABSTRACT Tunnelling in urban environments can significantly affect existing buried structures such as pile foundations. However, the current understanding of how tunnelling‐induced ground movements influence the stability and serviceability of piles remains limited. This knowledge gap presents potential risks that must be addressed during tunnel design

Abstract Sediments on Arctic continental shelves are impacted by sea ice and ice‐related processes for up to 9 months per year. As a result, seabed morphology in cold regions can exhibit features such as ice scours which are absent on lower‐latitude shelves.

How Does Heterogeneity Control Strain Localization Patterns in High‐Porosity Rocks?
Abstract We aim to explore how heterogeneous porosity and grain size contribute to strain localization patterns in highly porous rocks based on phase‐field simulations. The strain localization patterns, including shear bands, dilatation bands, and compaction bands, are commonly observed in geological field studies and laboratory experiments.

Abstract This study examined the spatiotemporal variability in geotechnical properties of beach cusp sediments on a sandy beach and tested if such variability can be used for cusp monitoring from satellite imagery. Specifically, sediment properties (including moisture content (w), relative density (Dr), sediment strength (QSBC) and friction angle (ϕ ...

Abstract Submarine landslides occur globally and have the potential to damage seafloor infrastructure and trigger tsunamis. Recently, diatomaceous weak layers have been hypothesized to play a role in triggering submarine landslides on passive continental margins by generating overpressure.

How Volume Increases the Mobility of Geophysical Granular Flow: A Unified Rheological Perspective
Abstract Geophysical granular flows, involving rapidly flowing granular materials, can exhibit volume‐enhanced mobility. Lacking a mechanistic understanding of such size effects limits the applications of lab‐scale findings to natural events. Using discrete element method simulations, we find that increasing granular system size suppresses energy ...

Hydraulic or Seepage Erosion: What Drives Bank Collapse in Tidal Environments?
Abstract The collapse of channel banks in tidal environments has typically been interpreted using fluvial concepts that prioritize hydraulic (flow‐driven) erosion. Yet daily tidal fluctuations trap pore water in channel banks, potentially producing sustained seepage flows capable of triggering collapse even without strong currents.

Hydraulic Control of the Foreshocks and Mainshock of the 2017 Valparaíso, Chile, Earthquake
Abstract Slow‐slip events (SSE) are a key mode of aseismic deformation and can enhance fault permeability through fracturing, enabling fluid migration from the overpressured oceanic crust to the plate interface. Whether the resulting poroelastic stress changes promote seismicity and larger megathrust events, however, remains unclear.
