Lithospheric Thinning of the Northeastern Arabian Margin Revealed by Matrix‐Free Teleseismic Traveltime Tomography

Geophysical Research Letters, Volume 52, Issue 3, 16 February 2025.
Abstract The obduction of the Tethys oceanic lithosphere is documented by the Semail ophiolite along the northeastern Arabian continental margin. Although the ophiolite is continuous and of similar age across the region, the eastern and western segments display distinct geological contrasts.

The admissible tsunamigenic source region of 24 September 2013 land-based earthquake application of backward ray tracing technique [PDF]

, 2015
A minor tsunami of about 50 cm was generated along the coast of Qurayat near Makran subduction zone in the Arabian Sea due to the 24 September 2013 Pakistan earthquake of magnitude 7.6 Mw(mB),although its source was ~200 km far inland of the Makran ...

Subduction Zone Obliquity Dictates Global Trench‐Parallel Inner Forearc Deformation

AGU Advances, Volume 6, Issue 1, February 2025.
Abstract Although subduction zones are characterized by convergence, the upper plates of subduction zones exhibit a diverse range of deformation styles that are often inconsistent with regional convergence. While several theories have been proposed to explain these variations, the underlying factors driving these differences are still not fully ...

Coeval Transverse and Axial Sediment Delivery to the Northern Hikurangi Trough During the Late Quaternary

Basin Research, Volume 37, Issue 1, January–February 2025.
Sediment delivery to the northern Hikurangi Trough has been driven by transverse gravity flows funnelled through the Māhia Canyon, alongside contributions from the overspill of the axial Hikurangi Channel. Large‐scale sediment waves and scours were formed by flows from the Māhia Canyon during MIS2 in response to substantially higher sediment fluxes ...

Upward delamination of Cascadia Basin sediment infill with landward frontal accretion thrusting caused by rapid glacial age material flux [PDF]

, 2004
The Cascadia convergent margin is a first-order research target to study the impact of rapid sedimentation processes on the mechanics of frontal subduction zone accretion.

Remagnetization of Pre‐Fan Sediments Offshore Sumatra: Alteration Associated With Seismogenic Diagenetic Strengthening

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 8, August 2024.
Abstract Increases in temperature and pressure caused by rapid burial of sediments seaward of the Sumatra subduction zone have been hypothesized to trigger dehydration reactions that diagenetically strengthen sediments and contribute to the formation of an over‐pressured pre‐décollement, which together facilitate the occurrence of large shallow ...

Dating and morphostratigraphy of uplifted marine terraces in the Makran subduction zone (Iran) [PDF]

, 2018
Abstract. The western part of the Makran subduction zone (Iran) has not experienced a great megathrust earthquake in recent human history, yet, the presence of emerged marine terraces along the coast indicates that the margin has been tectonically active during at least the late Quaternary.

Analogue Experiments of Subduction vs. Collision Processes: Insights for the Iranian Tectonics

, 2005
We investigate, using laboratory experiments, the behavior of subduction-collision transition. These experiments help understanding of the tectonics at the transition between the Zagros collision ranges and the Makran emerged accretionary prism in south ...

Cenozoic evolution of Neotethys and implications for the causes of plate motions [PDF]

, 2003
Africa-North America-Eurasia plate circuit rotations, combined with Red Sea rotations and new estimates of crustal shortening in Iran define the Cenozoic history of the Neotethyan ocean between Arabia and Eurasia. The new constraints indicate that Arabia-
