Probabilistic Seismic Hazard Assessment for United Arab Emirates, Qatar and Bahrain

Applied Sciences, 2020
A probabilistic seismic hazard assessment in terms of peak ground acceleration (PGA) and spectral acceleration (SA) values, for both 10% and 5% probability of exceedance in 50 years, has been performed for the United Arab Emirates, Qatar, and Bahrain. To

Crustal and Lithospheric Structures Beneath an Ophiolite Nappe, Southern New Caledonia, Southwest Pacific

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.
Abstract To understand ophiolite emplacement mechanisms in New Caledonia, southwest Pacific, we image crustal and lithospheric structures beneath southern Grande Terre, using seismic waveform data from a network (ITOPNC) of permanent and temporary stations (October 2018–November 2019). Surface wave dispersion indicates a 1–2 km thick ophiolite nappe on

The deformation pattern of subducting seamount: insights from the structural evolution of the Late Cretaceous Durkan Complex in the North Makran domain (Makran Accretionary Prism, SE Iran)

, 2022
The occurrence of topographic relief along the subducting plate is thought to play a significant role in controlling the architecture and the deformation processes of subduction complexes Seamounts and seamounts chain represent topographic reliefs of ...

TSUNAMIGENIC SOURCES IN THE INDIAN OCEAN [PDF]

Science of Tsunami Hazards, 2008
Based on an assessment of the repeat periods of great earthquakes from past seismicity, convergence rates and paleoseismological results, possible future source zones of tsunami generating earthquakes in the Indian Ocean (possible seismic gap areas) are ...

Geophysical Investigations of the Fujairah Basin, East Coast of United Arab Emirates: Insights Into Tectonic Evolution

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract The Fujairah basin in the Gulf of Oman experienced a complex tectonic evolution related to Late Cretaceous ophiolite obduction and Oligocene‐Miocene Zagros continental collision. The structure of the foreland basin in Oman‐UAE is well‐known, but the structure and evolution of the hinterland basin behind the obducted ophiolite and underlying ...

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.

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 ...
