External Vibrations on Early‐Age Concrete: A Review
Engineering Reports, Volume 8, Issue 5, May 2026.Scientific illustration of external vibration, their influencing properties and effects, possible outcomes and measures adapted. ABSTRACT Early‐age concrete exhibits limited mechanical strength, making it highly susceptible to external disturbances such as vibrations from construction activities, traffic, or nearby machinery which can disrupt internal ...

Engineering Reports, Volume 8, Issue 5, May 2026.Integrated VES, ERI, and MASW surveys, constrained by boreholes, delineate a central low‐resistivity/low‐V s weak corridor and more competent volcanic strata at depth. The eastern sector offers preferable foundation conditions, while identified weak zones require ground improvement or deep foundations to mitigate differential‐settlement risk.

Earthquake Spectra, Volume 42, Issue 2, May 2026.As seismic design paradigms shift toward functional recovery, there is a need for efficient methods to achieve desired decision variables (DVs), such as probability of replacement, repair cost, and downtime of the building, for seismically isolated buildings.

Earthquake Spectra, Volume 42, Issue 2, May 2026.In this paper, the physics‐based numerical simulation of the strongest instrumental earthquake in the recent seismic history of Italy, i.e., the Nov 23, 1980 Irpinia earthquake in Southern Italy, with magnitude MW 6.8, is presented and discussed. A 3D spectral element model covering an extended region (147 × 110 km2) was constructed, with a frequency ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Intermediate‐depth intraslab earthquakes in the Philippine Sea Plate occur at depths of 100–200 km beneath the Ryukyu Arc and are widely interpreted as manifestations of slab dehydration; however, the spatial variability in continuity of the volcanic front and the asymmetric distribution of volcanic activity are poorly explained by existing ...

Hunga‐Tonga Volcano Plumbing System Inferred From Virtual Seismometer Approach
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract We present a surface wave tomography application based on event‐pair interferometry to investigate local (∼100 km) mid‐ocean crustal structures, with a particular focus on imaging a potential crustal solidified intrusive complex in a region lacking seismic stations.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract In subduction zones, the locked seismogenic zone is bordered by an upper and a lower transition zone. In these transition zones, deformation is primarily accommodated by an interplay of diffuse viscous deformation within a weak matrix and brittle deformation in stiffer bands and blocks.
