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 ...

Earthquake Spectra, Volume 42, Issue 2, May 2026.We evaluate, select, and describe the ground‐motion models (GMMs) used in the 2025 update of the U.S. National Seismic Hazard Model (NSHM) for Puerto Rico and the U.S. Virgin Islands (PRVI). We identify the most appropriate models that align with GMM selection criteria for use in the PRVI region to improve the accuracy of seismic hazard assessments ...

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 ...

Tectonics and Sliver Motion in Costa Rica: Strain Partitioning Constrained by GNSS Velocities Data
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract The tectonic deformation of Costa Rica is controlled by the subduction of the Cocos Plate beneath the Caribbean Plate and the Panama microplate along the Middle America Trench, with oblique convergence in northern Costa Rica to 2024 from 154 permanent stations distributed across Costa Rica to derive for the first time spatially continuous ...

The Seismotectonic Map of Africa
Episodes, 2016 We present the Seismotectonic Map of Africa based on a geological, geophysical and geodetic database including instrumental seismicity and re-appraisal of large historical events, and harmonization and homogenization of earthquake parameters in the catalogues.

The Afghanistan Earthquake of 21 June 2022: The Role of Compressional Step-Overs in Seismogenesis
GeosciencesThe Afghanistan earthquake of 21 June 2022 ruptured a ~10 km-long fault segment in the North Waziristan–Bannu fault system (NWBFS) located towards the north of the Katawaz Basin. The earthquake was shallow and reportedly caused widespread devastation. In

Quaternary Segmentation Characteristics of the Hunhe Fault, Northeast China
Applied SciencesThe northern segment of the Tanlu fault zone, which encompasses the Dunhua–Mishan and Yilan–Yitong fault zones, plays a critical role in the tectonic framework of Northeast China. This study focuses on the Hunhe fault, part of the Liaoning segment of the
