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.

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.Landslide susceptibility mapping in India's Western Ghats using machine learning revealed high‐risk zones driven by deforestation, slope alteration and road proximity. The Random Forest model showed highest accuracy, supporting targeted mitigation, planning and early warning systems.

Earthquake Spectra, Volume 42, Issue 2, May 2026.This article presents a framework for performing a regional assessment of the accessibility of emergency healthcare facilities after a major earthquake. Accessibility is assessed by applying the enhanced two‐step floating catchment area method to a regional road network, implemented in ArcGIS.

Earthquake Spectra, Volume 42, Issue 2, May 2026.We perform linear mixed‐effects analyses with a ground‐motion dataset to evaluate how well ground‐motion models (GMMs) fit active crustal, subduction interface, and subduction intraslab earthquakes in Puerto Rico and the US Virgin Islands. Most of the GMMs reproduce the spatial variation in peak ground motions with earthquake magnitude and rupture ...

Rapid City‐Scale Earthquake Assessment by Combining Numerical Simulation and Sparse Sensing
Earthquake Spectra, Volume 42, Issue 2, May 2026.This study proposes a framework to assess the seismic risk by integrating city‐scale numerical simulations with sensor data prediction. The study begins with advanced numerical simulations using two primary methods: the integrated earthquake simulator (IES) and the stochastic Green's function method.

Marine record of late quaternary glacial-interglacial fluctuations in the Ross Sea and evidence for rapid, episodic sea level change due to marine ice sheet collapse [PDF]
Some of the questions to be addressed by SeaRISE include: (1) what was the configuration of the West Antarctic ice sheet during the last glacial maximum; (2) What is its configuration during a glacial minimum; and (3) has it, or any marine ice sheet ...

Earthquake Spectra, Volume 42, Issue 2, May 2026.The U.S. Geological Survey recently updated the National Seismic Hazard Model (NSHM) for Puerto Rico and the U.S. Virgin Islands (PRVI). The first version of the PRVI NSHM was released in 2003, and therefore this 2025 update includes over 20 years of new geologic, geophysical, and engineering data, methods, and models.

Earthquake Spectra, Volume 42, Issue 2, May 2026.This article aims at exploring and validating the use of 3D physics‐based simulated ground motions as seismic input for the derivation of seismic fragility curves based on nonlinear dynamic numerical analyses. Fragility curves are computed for a set of pre‐code (i.e., designed only for vertical loads), reinforced concrete building types representative ...

Earth and Space Science, Volume 13, Issue 5, May 2026.Abstract Seacliff erosion in steep terrain poses major risks to transportation and critical infrastructure. In Big Sur, California, USA, seacliff erosion threatens the sustainability of the central coast stretch of California State Route 1, a transportation corridor that is critical to the region's economy.
