“…Another significant effect is PGD, which can lead to soil liquefaction, landslide and ground failure. The individual and combined repercussions of these hazards can result in instability in the performance of pipelines, leading to substantial costs throughout the lifespan of the structure (Farahani et al, 2023). In the context of SRA for lifelines and infrastructure, investigating TGD and PGD are of paramount importance which are presented below.…”

The gas pipelines are a significant part of energy transportation pipelines and are recognized as a vital component of societal infrastructure. Earthquake-induced damage to gas pipelines can have severe disastrous humanitarian, social, economic, and ecologic consequences. To mitigate these consequences, one effective approach is to carefully design gas pipeline routes, considering the seismic hazard of the region. Conventional gas pipeline design methods consider only minimum distances from faults and fails to account for seismic potential of faults. This paper introduces a methodology that integrates seismic risk assessment into the gas pipeline route design process. Seismic risk is performed using the HAZUS method, and pipeline routing optimization is accomplished through the application of a metaheuristic algorithm within a GIS-based framework. The methodology is applied in to three gas pipeline routing problems within the high seismic region of southern Iran. The results are then compared with conventional approaches, considering factors such as route length, seismic risks, and seismic damage costs. The findings demonstrate the proposed method effectiveness in mitigating seismic risks related to gas pipeline. The proposed method enables a quantitative and direct incorporation of seismic risk into gas pipeline routing, marking a departure from the qualitative methods presently in use.

“…Given the variability in ground motion parameter intensities across different areas, the necessity for a seismic hazard map is evident. These maps inform seismic macrozonation [19,20], pipeline route design, land-use planning, building codes, and disaster preparedness efforts [21], necessitating hazard analyses across multiple points [22]. In a pipeline route design project, a macro assessment of seismic hazards is essential to evaluate the seismic hazard and consequence seismic risk of each candidate route.…”

Earthquake hazard mapping assesses and visualizes seismic hazards in a region using data from specific points. Conducting a seismic hazard analysis for each point is essential, while continuous assessment for all points is impractical. The practical approach involves identifying hazards at specific points and utilizing interpolation for the rest. This method considers grid point spacing and chooses the right interpolation technique for estimating hazards at other points. This article examines different point distances and interpolation methods through a case study. To gauge accuracy, it tests 15 point distances and employs two interpolation methods, inverse distance weighted and ordinary kriging. Point distances are chosen as a percentage of longitude and latitude, ranging from 0.02 to 0.3. A baseline distance of 0.02 is set, and other distances and interpolation methods are compared with it. Five statistical indicators assess the methods. Ordinary kriging interpolation shows greater accuracy. With error rates and hazard map similarities in mind, a distance of 0.14 points seems optimal, balancing computational time and accuracy needs. Based on the research findings, this approach offers a cost-effective method for creating seismic hazard maps. It enables informed risk assessments for structures spanning various geographic areas, like linear infrastructures.
