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 ...

Sensitivity Analysis of the Thermal Structure Within Subduction Zones Using Reduced‐Order Modeling

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract Megathrust earthquakes are the largest on Earth, capable of causing strong ground shaking and generating tsunamis. Physical models used to understand megathrust earthquake hazard are limited by existing uncertainties about material properties and governing processes in subduction zones.

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

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 ...

Tsunami Vulnerability Analysis of Makran Subduction Zone through Fuzzy Logic

Indonesian Journal on Geoscience
Tsunamis are among the most terrifying natural hazards, causing significant loss of life and property and impacting our society’s human, economic, and social aspects. Given their destructive nature, developing effective techniques for tsunami observation and demolition reduction is crucial. This study proposes a novel tsunami detection and alert system

Seismic Site Amplification Characteristics of Makran Subduction Zone Using 1D Non-Linear Ground Response Analysis

Applied Sciences
The Makran Subduction Zone (MSZ) is a tectonic plate boundary where the Arabian Plate is subducting beneath the Eurasian Plate. This study investigated the dynamic response in the Gwadar region, located in the eastern part of the MSZ.
