Tsunami and the effects on coastal morphology and ecosystems: A report [PDF]

, 2012
Tsunamis are one of the most destructive natural hazards that affect the coastal areas. Tsunami waves that impact the coast with enormous energy are capable of destroying the objects on the coast and re-shaping the coastal geography, geomorphology and ...

Morphotectonics of the central Muertos thrust belt and Muertos Trough (northeastern Caribbean) [PDF]

, 2009
Multibeam bathymetry data acquired during the 2005 Spanish R/V Hespérides cruise and reprocessed multichannel seismic profiles provide the basis for the analysis of the morphology and deformation in the central Muertos Trough and Muertos thrust belt ...

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.

Chromian spinel geochemistry as a petrogenetic indicator in the chromitites and peridotites of the Bajgan Complex, Western Makran [PDF]

پترولوژی
IntroductionEconomic chromite deposits are very common in ophiolite belts. These deposits usually occur in the uppermost horizons of the ophiolite mantle sequence or within the ultramafic cumulitic rocks at the base of the crustal sequence (González ...

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

Ridge subduction at an erosive margin - the collision zone of the Nazca Ridge in southern Peru [PDF]

, 2004
The 1.5-km-high, obliquely subducting Nazca Ridge and its collision zone with the Peruvian margin have been imaged by wide-angle and reflection seismic profiles, swath bathymetry, and gravity surveying.

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 ...

Structure of the Makran subduction zone from wide-angle and reflection seismic data

Tectonophysics, 2000
Abstract Makran is one of the largest accretionary wedges on the globe, formed by the convergence between the Eurasian and the Arabian Plates. It is characterised by an extremely high sediment input of 7 km and a shallow subduction angle. We present seismic velocity models from four wide-angle seismic lines that image the wedge sediments and the ...

Backstop geometry and accretionary mechanics of the Sunda margin [PDF]

, 2003
The convergent Sunda margin off Indonesia displays all geological features characteristic of an accretion-dominated subduction zone. A combined interpretation of prestack depth-migrated seismic reflection data and velocity information gained from ...
