Investigating Uncertainty in Seismic Design Maps Based on Hazard and Fragility Curves [PDF]
پژوهشهای زیرساختهای عمرانیAll engineering measurements carry inherent uncertainty, whether acknowledged or not. If we add a type of risk metric as well as uncertainty quantification in the procedure of establishing the seismic design load applied to the structures, we will have a

Probabilistic seismic hazard assessment for Iraq
Journal of Seismology, 2020 Probabilistic seismic hazard assessments (PSHA) form the basis for calculating seismic loads in most contemporary seismic provisions in building codes around the world. The current building code of Iraq, which was published in 1997, is currently undergoing a significant engineering update. This study was undertaken in order to support the building code

A probabilistic approach to the seismic hazard in Kashmir basin, NW Himalaya
Geoscience Letters, 2019 Northwestern Himalaya is one of the most tectonically active domains of the Himalayan arc. The prevailing complex collisional tectonic setup is able to produce destructive earthquakes, most recent being the 8 October 2005 Kashmir earthquake (M7.6).

Deep Underground Science and Engineering, EarlyView.This study presents an integrated workflow to evaluate secure and large‐scale CO2 storage in depleted oil reservoirs of the Cambay Basin, India. Industrial CO2 sources are systematically matched with mature oil fields using a quantitative source–sink framework to minimize transport distance and cost.

World's fastest 10 000‐m breakthrough: The XY‐22 well redefines deep‐earth access in the Tarim Basin
Deep Underground Science and Engineering, EarlyView.The Tarim Basin in northwestern China hosts one of the world's deepest petroleum systems, exemplified by the XY‐22 ultra‐deep well (bottom depth: 11 116 m; ~220°C, ~145 MPa). This study integrates tectonic mapping, geological cross‐sections, ultraviolet fluorescence microscopy, and optical photothermal infrared (OPTIR) spectroscopy to characterize ...
