Terrane Collision‐Induced Subduction Initiation: Mode Selection and Implications for Western Pacific Subduction System

Geochemistry, Geophysics, Geosystems
In the regime of plate tectonics, the subduction of an oceanic plate generally terminates with the collision and accretion of continental terranes. Then, a new subduction zone may form in the neighboring oceanic plates, which is defined as the terrane ...

Subduction initiation in mid-ocean induced by mantle suction flow

, 2018
Pre-existing weakness zones in the lithosphere such as transform faults/fracture zones and extinct mid-oceanic ridges have been suggested to facilitate subduction initiation in an intra-oceanic environment.

Subduction initiation without a prescribed weak zone: What’s gonnahappen?

, 2017
International audienceSubduction initiation is one of the main unclear aspect of plate tectonics. When studying subduction processes,subduction initiation is therefore generally avoided as it constitutes a problem in itself.

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

Intraplate Basalts in Eastern Continental China Record the Subduction History of the Pacific Plate

Geophysical Research Letters
To assess whether intraplate magmatism in eastern continental China records the subduction history of the Pacific plate, we plotted elemental compositions of the volcanic rocks in this region since the Early Cretaceous as a function of age.

Evaluating the U.S. Geological Survey's Earthquake Shaking Hazard Forecasts and Their Implications on Seismic Risk

Earthquake Spectra, Volume 42, Issue 3, August 2026.
We analyze the last six update cycles of the long‐term probabilistic earthquake shaking hazard forecast from the U.S. Geological Survey (USGS) and discuss the changes in hazard estimates from the 1996 to the latest 2023 update of the National Seismic Hazard Model (NSHM) for the conterminous United States.

Seismic Fragility and Vulnerability of Partially Grouted Flexural‐Controlled Reinforced Masonry Buildings in Colombia

Earthquake Spectra, Volume 42, Issue 3, August 2026.
This paper presents the development of analytical fragility and vulnerability functions for flexure‐controlled partially grouted reinforced masonry (RM) buildings that are representative of Colombian urban areas, with the goal of enhancing national seismic risk assessments.

Upright emplacement of the Gibraltar slab and the origin of rifting in adjacent foreland and Backarc Basins

Communications Earth & Environment
Back-arc basins in subduction systems usually form following discrete subduction-related extension stages. However, in the westernmost Mediterranean, the initiation of Cenozoic extension associated with the Valencia Trough and Algerian Sea Basin ...

Assessments of Liquefaction Triggering and Manifestation at Three Case History Sites in Napier Based on 1931 Hawke's Bay, New Zealand, Earthquake

Earthquake Spectra, Volume 42, Issue 3, August 2026.
The 1931 Hawke's Bay earthquake (∼MS 7.8) stands as one of New Zealand's most devastating, causing widespread liquefaction and damage across the city of Napier. However, Napier remains underrepresented in liquefaction hazard studies as compared to other regions in the country.
