Global Positioning System (GPS) Determination of Motions, Neotectonics, and Seismic Hazard in Trinidad and Tobago

open access: yes, 2008
The twin island nation of Trinidad and Tobago is located in the actively deforming Caribbean-South American (Ca-SA) plate boundary zone. Geodetic GPS work over the past decade has accurately determined present-day Ca-SA relative plate motion.

Soil Gas Investigations in Hatay‐Reyhanlı (Türkiye): Implications for Buried Fault Detection and Seismic Hazard Assessment

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract This study presents a soil gas geochemical survey in the Kırcaoğlu and Reyhanlı regions of Hatay Province, southeastern Türkiye, following the 2023 Kahramanmaraş earthquake doublet. The aim was to identify concealed faults and assess seismic hazard through analysis of soil CO2 flux, CO2 and 222Rn concentrations, and carbon and helium isotopic ...

Neotectonics and seismicity of the Urals

open access: yesIzvestiya vysshikh uchebnykh zavedenii. Gornyi zhurnal, 2022
Introduction. The Ural submeridional mountain belt is an epipaleozoic orogen rejuvenated in the contemporary period (in the Neogene-Quaternary period in the last 20–30 million years). In the pre-Paleozoic era, the Urals developed as a submeridional upland, presumably as a result of the interaction (clash) between the East European and West Siberian ...

Crustal Structure Across the Okavango Rift, Botswana: The SEISORZ Wide‐Angle Seismic Experiment

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract The Okavango Rift Zone (ORZ) is an incipient continental rift in Botswana at the terminus of the Southwestern Branch of the East African Rift System. The lack of syn‐rift magmatism and tectonic processes overprinting pre‐rift structures provide an opportunity to investigate incipient‐stage rift processes and the role of pre‐existing structures

Evaluation of GPR capabilities in the study of seismogenic faulting and deformation in the bottom sediments of Lake Upoloksha (northeast of the Fennoscandian shield)

open access: yesГеодинамика и тектонофизика, 2018
The article describes the experience of using the GPR method to study the bottom sediments of Lake Upoloksha located in the Kola Peninsula, Russia. Such sediments are viewed as good archives of various Holocene geodynamic processes, including tectonic ...

The internal structure of Beypazarı Blind Thrust Zone around Çayırhan

open access: yesBulletin of the Mineral Research and Exploration, 2020
The Beypazarı Blind Thrust Zone, which is surrounded by the North Anatolian, the Eskişehir, and the Kırıkkale-Erbaa fault zones, is a recently defined neotectonic structure developed in the NW central Anatolia together with the Eldivan-Elmadağ and the ...

Recent Pedogenesis and Neotectonics affecting Archaeological Sites in North Yemen

open access: yes, 1989
A holocene pedogenetic phase identified in the central highlands of North Yemen, as well as a renewal of very recent neotectonic movements, are related to the history of different archaeological sites found in the area, ranging in age from the lower ...

Cave Palaeolithic of the Ural Mountains – a review

open access: yesBoreas, Volume 55, Issue 1, Page 4-28, January 2026.
The Ural Mountains are of fundamental importance for studying early human migrations along the geographical limits between Europe and Asia. Geological processes and past climates gave rise to numerous caves, mostly in Palaeozoic carbonate formations.

Active tectonics in Quaternary marine formations in the Tangier region (North West Rif, Morocco): Persistent Scatterer (PSInSAR) contribution

open access: yesGeogaceta
This study investigates recent tectonic activity in Tangier, Morocco, using PSInSAR data and microtectonic field observations. The exploration of marine deposits in the Achakar basin during the Plio-Quaternary period holds significance for tracking the ...

On a flawed conclusion that the 1255 A.D. earthquake ruptured 800 km of the Himalayan Frontal Thrust east of Kathmandu

open access: yesGeophysical Research Letters, 2016
A reexamination of the observations and analysis recently reported to conclude that an 800 km section of the Himalayan Frontal Thrust ruptured in 1255 A.D. shows that the conclusion is flawed and without merit because of misinterpretations of trench logs
