Like other large-scale development projects, the design, construction, and utilization of subway projects have several positive negative environmental consequences. In this study, geological hazards in construction phase Ahvaz Subway Line 1identified localized. The impacts also were assessed surface subsurface sections. During evaluation, after providing preparing required information layers, A...

Large seismogenic faults consist of approximately meter-thick fault cores surrounded by hundreds-of-meters-thick damage zones. Earthquakes are generated rupture propagation and slip within dissipate the stored elastic strain energy in fracture frictional processes zone radiated seismic waves. Understanding this partitioning is fundamental earthquake mechanics to explain dynamic weakening causat...

The fragility of buried electrical cables is often neglected in earthquakes but significant damage to cables was observed during the 2010–2011 Canterbury earthquake sequence in New Zealand. This study estimates Poisson repair rates, similar to those in existence for pipelines, using damage data retrieved from part of the electric power distribution network in the city of Christchurch. The funct...

In this study, it is attempted to analyze sensitivity and reliability in order to evaluate the liquefaction potential in soil layers in Tabriz. 62 boreholes that had possible conditions for liquefaction were selected. Seismic mapping was simulated using finite fault method and then the effect of soil layers on PGA was estimated. In continue, the liquefaction potential index was estimated and th...

The aim of the study is to clarify the vitreous body structure and liquefaction phenomena. It was found that when melting a frozen rabbit vitreous body, the gel-sol transition phenomenon occurs and the gel structure is broken. This is almost like the liquefaction of the vitreous body in vivo. We try to clarify the liquefaction phenomenon by using this animal model. The native vitreous body has ...

Geological identification of tsunami deposits is important for tsunami hazard studies, especially in areas where the historical data set is limited or absent. Evidence left by historical tsunamis in the coastal sedimentary record of the Gulf of Corinth was investigated by trenching and coring in Kirra on the north coast and Aliki on the south coast. The Gulf of Corinth has a documented tsunami ...

The Boumerdes-Algiers earthquake of magnitude Mw:6.8 is the second major event which seriously affected Algeria in the last twenty years. This seismic event, located 7 km north of the village of Zemmouri (50 Km east of Algiers) happened in a region characterized previously by a low to moderate seismic activity. With a depth of 10 km, the earthquake killed 2300 persons and caused huge damage in ...

The liquefaction of crop residues in the presence of ethylene glycol, ethylene carbonate, or polyethylene glycol using sulfuric acid as a catalyst was studied. For all experiments, the liquefaction was conducted at 160°C and atmospheric pressure. The mass ratio of feedstock to liquefaction solvents used in all the experiments was 30:100. The results show that the acid catalyzed liquefaction pro...

In this paper, we study how coseismic deformations calculated in 1066 Earth models are affected by the treat discontinuities. From results of applying 1066A (continuous) and 1066B (discontinuous), find that difference Love numbers strike-slip horizontal tensile sources bigger than dip-slip vertical sources. Taken collectively, discontinuities have major effects on Green’s functions four indepen...
