Testing the influence of far-field topographic forcing on subduction\ud initiation at a passive margin

, 2014
Despite favourable gravitational instability and ridge-push, elastic and frictional forces prevent subduction initiation fromarising spontaneously at passive margins.

Subduction initiation and ophiolite crust: new insights from IODP drilling

, 2017
International Ocean Discovery Program (IODP) Expedition 352 recovered a high-fidelity record of volcanism related to subduction initiation in the Bonin fore-arc. Two sites (U1440 and U1441) located in deep water nearer to the trench recovered basalts and

An Intensity Measure‐Based Methodology for Ground Motion Orientation in Seismic Structural Assessment

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 15, Page 3859-3879, December 2026.
ABSTRACT In current dynamic time history assessment protocols, ground motion recordings are mostly oriented along fixed sensor directions. Consequently, the orientation of the principal resultant of rupture energy, which may control the maximum structural demand, remains undefined, precluding consistent correlation with physically detrimental ...

Selected Physical and Geotechnical Properties of Loess in Wairarapa Valley, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Loess up to 10 m thick covers marine terraces, old river aggradation terraces, and gentle hill country slopes in Wairarapa, New Zealand. In the drier eastern and southern parts of Wairarapa, the loess is subject to dry summer and autumn and wet winter and spring in most years.

Numerical analysis of deformation in the upper part of subduction zones [PDF]

, 1981
The stresses and deformation in an accretionary prism, and the crystalline basement behind and beneath it, have been modelled using finite element analysis, assuming a visco-elastic Maxwell rheology for the rocks involved.

Late Cenozoic Sediment Provenance in the Northern Canterbury Basin, Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Late Cenozoic strata of the northern Canterbury Basin record uplift and erosion of mountain ranges adjacent to the transition from oblique subduction to strike‐slip on the Australian–Pacific plate boundary. Using the provenance of conglomerate clasts and sandstone samples, we reconstruct sediment transport pathways and, by inference, exhumation and ...

Feasibility of a National Earthquake Early Warning System for New Zealand: The Propagation of Local Undamped Motion Algorithm Evaluated on a Physics‐Based Synthetic Earthquake Catalogue

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Earthquake early warning (EEW) can reduce injuries and damage by issuing alerts before incoming shaking. We evaluate the Propagation of Local Undamped Motion (PLUM) algorithm as a candidate for a national EEW system for Aotearoa New Zealand (NZ). We develop and demonstrate a novel methodology for evaluating EEW performance under a wide range of future ...

Late Pliocene–Quaternary Arc Volcanism at the Southern Limit of the Hikurangi Subduction Zone: Revised Chronology of the Taranaki Peninsula, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Igneous centres across the Taranaki Peninsula represent the southwestern limit of arc volcanism associated with the Tonga–Kermadec–Hikurangi subduction system. Taranaki Maunga, the youngest and largest of three andesitic stratovolcanoes, dominates the geomorphology of the Taranaki Peninsula along with the eroded remnants of the Kaitake and Pouakai ...

Cretaceous–Palaeogene Plate Boundary Evolution at the Pacific Margins of Zealandia and West Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Improved satellite‐derived gravity data support updated interpretations and models of ancient plate boundaries and plate motions affecting Zealandia and West Antarctica. The models combine to confidently resolve hundreds of kilometres of Late Cretaceous–Eocene motion between the Pacific and Lord Howe plates, confirming that plate circuit constructions ...
