Convergence of 29 ± 1 mm/yr between the NW corner Indian plate and Asia is accommodated by a combination thrust strike‐slip faulting on prominent faults apparent distributed deformation within Hindu Kush, Pamir, South Tien Shan Kohistan Ranges. An upper bound to slip rate known obtained ignoring strain rotation: convergence occurs north Peshawar Basin (13 mm/yr) in Alai‐South (12 2 mm/yr), shear northeast‐trending northern Chaman‐Gardiz‐Konar system (18 1mm/yr) Darvaz‐Karakul fault zone (11...
Abstract The Cenozoic convergence between India and Asia has created Earth's thickest crust in the Pamir‐Tibet Plateau by extreme crustal shortening. Here we study structure of Pamir western Tian Shan, adjacent margins Tajik, Tarim, Ferghana Basins, Hindu Kush, using data collected temporary seismic experiments. We derive, compare, combine independent observations from P S receiver functions. obtained Moho depth varies ~40 km below basins to a double‐normal thickness 65–75 underneath Kush. A...
<p>Central Asia is one of the seismically most active regions in world. Its complex seismicity due to collision Eurasian and Indian plates has resulted some world’s largest intra-plate events over history. The region dominated by reverse faulting strike slip normal events. GSHAP project (1999), aiming at a hazard assessment on global scale, indicated that Central characterized peak ground accelerations for 10% probability exceedance 50 years as high 9 m/s<sup>2</sup>.

Abstract. Central Asian countries, which include Kazakhstan, the Kyrgyz Republic, Tajikistan, Turkmenistan, and Uzbekistan, are known to be highly exposed natural hazards, particularly earthquakes, floods, landslides. With aim of enhancing financial resilience risk-based investment planning promote disaster climate in Asia, European Union, collaboration with World Bank GFDRR, launched a regional program for “Strengthening Financial Resilience Accelerating Risk Reduction Asia” (SFRARR)....
Abstract. Central Asia is an area characterized by complex tectonic and active deformation, largely due to the relative convergent motion between India Arabia with Eurasia. The resulting compressional regime responsible for development of significant seismic activity, which, along other natural hazards such as mass movements river flooding, contributes increased risk local populations. Although several studies have been conducted on individual perils at national levels, last published...

This study presents an integrated approach to seismic microzonation in urban environments, emphasizing the importance of dynamic numerical modeling enhancing earthquake hazard assessments. Our goal was deepen understanding wave behavior soils city Dushanbe by combining extensive geological, geophysical, and engineering datasets. These datasets include macroseismic data, local geological observations, detailed geophysical surveys conducted between 2019 2020. The consisted five Microtremor...
Abstract Seismologic and geologic fault‐slip data characterize the active deformation of intramontane Tajik basin its margins, Tian Shan, Pamir, Hindu Kush at northwestern tip India‐Asia collision zone. Within this complexly deforming region, lithosphere forms backstop for north‐dipping Indian‐slab subduction beneath but itself delaminates retreats west northward Pamir. Herein, we link crustal to these lithosphere‐scale processes, using from recently deployed seismic networks observations....
Abstract Geodetically derived velocities from Central Asia show that Northern Afghanistan, the Tajik Pamir, and northwestern Pakistan all move northward with comparable large toward Eurasia. Steep velocity gradients, hence high strain rates, occur only across Main Pamir Fault zone lesser magnitude between northernmost Hindu Kush south southeast margins of Depression. Localized shortening is not apparent on any active India‐Hindu crustal boundary; hence, convergence India Eurasia in absorbed...
Abstract At the northwestern tip of India‐Asia collision zone, Pamir orocline overrides Tajik Depression and Tarim Basin collides with Tian Shan. Currently, Pamir's northern edge exhibits localized shortening rates 13–19 mm/yr. While eastern move northward nearly en block, north‐south decreases westward along front into Depression. In northeastern Depression, wedge‐shaped crustal sliver Peter First Range is squeezed between dextral‐transpressive Vakhsh sinistral‐transpressive Darvaz faults....

In the territory of Dushanbe city, capital Tajikistan, detailed geological and geophysical data were collected during surveys in 2019–2020. The comprise 5 microtremor array measurements, 9 seismic refraction tomography profiles, seismological from temporary stations for standard spectral ratio calculations, 60 borehole datasets, 175 ambient noise measurements. complete dataset was used to build a consistent 3D geologic model city with size 12 × km2. results compared calibrated define...
Abstract. In this study, we have created 10 geoscience video lessons that follow the paired-teaching pedagogical approach. This method is used to supplement standard school curriculum with lessons, instructed by geoscientists from around world, coupled activities carried out under guidance of classroom teachers. The introduce students scientific concepts behind earthquakes (e.g. Earth's interior, plate tectonics, faulting, and seismic energy), earthquake hazards, mitigation measures...

Being a country exposed to strong seismicity, the estimation of seismic hazard in Tajikistan is essential for urbanized areas, such as rapidly growing capital city Dushanbe. To ensure people’s safety and adequate construction work, detailed microzonation key proper planning. Existing estimations date back 1978; they are based on engineering geological investigations observed macroseismic data. Thereupon relies Tajik Building Code, which considers intensities according...
