DataSheet1_Magmatic fingerprints of subduction initiation and mature subduction: numerical modelling and observations from the Izu-Bonin-Mariana system.PDF [PDF]

Understanding the formation of new subduction zones is important because they have been proposed as the main driving mechanism for plate tectonics and they are crucial for geochemical cycles on Earth.

Rapid Changes in Southern Ocean Upper‐Water Temperature Linked to Shift of the Southern Hemisphere Westerlies Since the Last Glacial

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The pattern and cause of upper‐water temperature (UWT) variations on millennial timescales in the Southern Ocean (SO) and the mechanism of their interaction with high‐latitude Northern Hemisphere climate remain unclear. Here, we reconstructed millennial‐scale subsurface temperature (subST) records from the Weddell Sea during the Last Glacial ...

Gravitational Stability of Hydrated SiO2 and Basaltic Crust in the Lower Mantle

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract We determined thermal equations of state of hydrated stishovite and CaCl2‐type SiO2 up to 100 GPa and 3,000 K to assess the gravitational stability of hydrated stishovite and basaltic crust in the lower mantle. Using machine‐learning based atomistic simulations, we examined three hydrogen dissolution mechanisms: hydrogarnet‐type, interstitial ...

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 ...

THE EARLY PRECAMBRIAN EFFECT OF OCEANIC CRUSTAL THICKNESS ON THE SUBDUCTION STYLE OBTAINED BY NUMERICAL PETROLOGICAL AND THERMOMECHANICAL MODELING

Геодинамика и тектонофизика
Eclogitization of magmatic rocks in the oceanic crust plays a key role in the mechanism of the lithospheric plate movement. This effect (as well as its kinetic delay) is particularly important in the Precambrian subduction when oceanic crust could be ...

Estimating Arias Intensity From Response Spectrum

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2169-2183, August 2026.
ABSTRACT Arias intensity serves as a crucial metric to measure ground motion energy and is extensively utilized in earthquake engineering to analyze structural damage, slope instability, and the potential for soil liquefaction. Nevertheless, in many practical design scenarios, only the response spectrum is available, without corresponding information ...

Comparison of Seismic Performance Assessment Using Observed or Simulated Ground Motions in Seismic Hazard Analysis and Ground Motion Selection

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2449-2465, August 2026.
ABSTRACT This paper illustrates opportunities for the use of simulated ground motions in seismic performance assessment – from seismic hazard, ground‐motion selection, response history analysis, and seismic demand hazard calculation. The illustration is through a comparative analysis with the conventional alternative of observed ground motions.

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.
