Rupture of the 1949 Khait Earthquake on a Cryptic Fault: Implications for Earthquake Hazard

Tectonics, Volume 44, Issue 10, October 2025.
Abstract The 1949 Mw 7.6 Khait earthquake, Tajikistan, was one of the most destructive of the Pamir—Tien Shan region, killing over 7,000 people by building collapse and landsliding. It occurred at the transition between the Pamir and Tien Shan mountain ranges, which converge along the narrow Vashkh river valley.

PROVENANCE OF KARAKUM DESERT SAND (TURKMENISTAN): LITHIC-RICH OROGENIC SIGNATURE OF CENTRAL ASIAN DUNE FIELDS

Rivista Italiana di Paleontologia e Stratigrafia, 2018
Major deserts do not necessarily consist of eolian dunes as quartz-rich as those of the Great Nafud, Rub’ al Khali, Sahara, and Mega-Kalahari sand seas accumulated in anorogenic settings of Arabia and Africa. The Karakum dune field of Turkmenistan is one

Coupling of Tectonics, Climate, and Lithology in Orogenic Systems: Insights From Cosmogenic 10Be Erosion Rates and River Profile Inversion Modeling in the Talesh Mountains, NW Iranian Plateau

Tectonics, Volume 44, Issue 2, February 2025.
Abstract The landscape of the Talesh Mountains, located in the NW sector of the Iranian Plateau (within the Arabia‐Eurasia collision zone), results from the interplay of multiple forces. To explore the interaction between tectonics, climate, and lithology we present 11 new erosion rates derived from meteoric 10Be on the eastern (wetter) and western ...

Block Rotations in NW Iran in Response to the Arabia‐Eurasia Collision Constrained by Paleomagnetism

Tectonics, Volume 43, Issue 8, August 2024.
Abstract Northwest Iran is a seismically active region dominated by NW‐SE trending strike‐slip faults, such as the North Tabriz and Qosha Dagh faults, and smaller NNE‐SSW striking faults. The Bozgush Mountains are shaped by these faults and divided into two domains that show a difference in strike. To quantify rotational tectonic deformation in NW Iran,

Provenance and Fluvial‐Aeolian Process of Kyzylkum Desert: Constrained by Detrital Zircon U–Pb Dating

Geophysical Research Letters, Volume 51, Issue 13, 16 July 2024.
Abstract The Kyzylkum Desert, as a transition area of different dust source in Central Asia, provides and reserves a large amount of dust transported by different atmospheric circulation systems, affecting Uzbekistan and downwind East Asia. However, there remains very few investigations about sediment sources and control factors of the desert.

A comprehensive review of HVS‐I mitochondrial DNA variation of 19 Iranian populations

Annals of Human Genetics, Volume 88, Issue 3, Page 259-277, May 2024.
Abstract Iran is located along the Central Asian corridor, a natural artery that has served as a cross‐continental route since the first anatomically modern human populations migrated out of Africa. We compiled and reanalyzed the HVS‐I (hypervariable segment‐I) of 3840 mitochondrial DNA (mtDNA) sequences from 19 Iranian populations and from 26 groups ...

Investigating the Reliability of Ground Motion Intensity Measures

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
The uncertainty and unreliability in the probabilistic seismic demand models (PSDMs) can be addressed in the framework of performance‐based earthquake engineering (PBEE). Some characteristics have been introduced and extensively investigated in the earthquake engineering literature for appropriateness (i.e., optimality) of various intensity measures ...

The occurrence of Neoflabellina bioevents across the Coniacian/Santonian boundary in the Abderaz Formation, Kopeh-Dagh Basin, Iran

Stratigraphy, 2020
In this study, Abderaz Formation at six stratigraphical sections, in east and center of the Kopeh-Dagh sedimentary basin, has been investigated, based on biserial planktonic foraminifera. Totally, 831 samples, with 3 meter distance, were gathered from a sequence with 2800 meter thickness. Also 4 genera and 17 species of biserial planktonic foraminifera

Investigating the Resilience of Urban Passages Against Earthquakes (Case Study: Jajarm City) [PDF]

مطالعات جغرافیایی مناطق کوهستانی
IntroductionConsidering that the vulnerability of the physical part of the city has a direct effect on the human casualties caused by the crisis. Vulnerability is usually aggravated as a result of indiscriminate constructions in the boundaries of faults,
