Liquefaction hazard assessment in a seismically active region of Himalayas using geotechnical and geophysical investigations: a case study of the Jammu Region

Abstract: The Jammu Region (JR) in the northwestern Himalayas trigged by medium to high magnitude near-field as well as far-field earthquake events, including the most recent 2019 Mirpur earthquake. In this paper, an attempt has been made to develop the zonation map for liquefaction hazard in the JR based on liquefaction potential index ( ) and probability of liquefaction ( ). To achieve this, factor of safety against liquefaction was estimated using standard penetration test (SPT) data collected… Show more

“…Lining spalling and portal collapses were the most visible seismic damage in multiple mountain tunnels during the 1999 Chi-Chi earthquake and the 2008 Wenchuan earthquake During these two earthquakes, most of the tunnels exhibit extensive lining deformation. The two principal portal failure types are stratum deformation and spandrel cracking (Ansari et al 2022a , b ). The most typical types of pavement damage seen in tunnels affected by large magnitude earthquakes are uplift, cracking, and groundwater leakage in construction joints and concrete lining (Yu et al 2016 ).…”

“…The 2005 Kashmir earthquake (M w =7.6) was one of the worst, with over one lakh people killed and infrastructure projects including bridges, retaining walls, and dams destroyed (Durrani et al 2005 ). This area has witnessed mega infrastructural projects including bridge abutment, tunnelling, and expansion of railway tracks and national highways, which are going to help the overall economic development of the region (Ansari et al 2022a , b ). The Udhampur Srinagar Baramulla Rail Link (USBRL) project is a 345 km long mega rail project in the Himalayan terrain that is bordered by active seismic sources such as the Main Boundary Thrust (MBT) and Main Central Thrust (MCT).…”

“…Among these soil investigation data, SPT is the most used data. SPT data was also used in the study of liquefaction potential in the Jammu Region, India [18], Roorkee Region, India [19], Kathmandu Valley in Nepal [20], Imperial Valley, California [21], Surat City, India [22]. Currently, there are limited number of studies on liquefaction potential analysis in coastal areas in Indonesia.…”

“…Liquefaction is one of the most devastating seismic hazards related to earthquakes in the world. It occurs when earthquake shaking and increased pore water pressure reduce the strength and stiffness of soil (Marcuson, 1978;Papathanassiou et al, 2011;Tehran et al, 2016;Bahari et al, 2020;Ansari et al, 2022). Therefore, the evaluation of the liquefaction susceptibility and its resistance is an important component of seismic hazard assessment in an earthquake-prone region.…”
