“…Numerous equations have been proposed in the literature for clean sand correction. Thus, when empirically obtained using liquefaction case history data, and accounting for the impacts of fines content to the CRR [23], it is expressed as: N 1(60)cs = N 1(60) + ∆N 1(60) (11) Figure 8 presents the correction values according to the amount of fines content in respect to various approaches developed for clean sand correction [27,[31][32][33]. It is clear from the figure that the Idris and Baulanger [27] curve seems to plot an average of all other proposed curves.…”

“…The authors believe that the average safety factor for the site can provide valid liquefiable soil depth evidence. Wadi et al [11] conducted another study, which followed similar steps, by investigating the data from 28 boreholes with SPT measurements. The authors reported that saturated subsurface fine-grained soil up to a depth of 4 m had a low factor of safety (F.S.)…”

Cyprus is the third largest and populated island in the Mediterranean Sea, and is still rapidly expanding. Significant infrastructures, such as hotels, educational institutions, and large residential complexes, are being built. Historically, 15 destructive earthquakes were reported on Cyprus from 1896 to 2019 that caused structural damages and casualties. In this study, the liquefaction potential of Tuzla and Long Beach on the east coast of Cyprus is estimated using the standard penetration test (SPT) data from more than 200 boreholes at different locations at the sites. The overall results are presented in a liquefaction potential index obtained from the factor of safety (F.S.) coefficient. Both study areas are susceptible to liquefaction. Thus, liquefaction potential maps are prepared to identify hazards in Tuzla and Long Beach. Additionally, the average factor of the safety line was introduced for both sites to create a correlation between the liquefaction area and F.S. values of every borehole. The adopted approach precisely provides the liquefiable regions when compared with historical evidence, CPT measurements, surface geology aspects, and geospatial data. Additionally, the results prove that the liquefaction potential must be considered during the design stage of new infrastructure in these areas.

“…Following investigation, researchers indicated that the soil up to 15 meters deep had a considerable liquefaction risk at successive depths in the majority of drilling locations [22]. Using information from 28 boreholes, Wadi et al (2021) carried out a similar case study at a sugar plant location in Nigeria's Upper Benue area to assess subsurface formation for soil liquefaction analysis. According to the method in Idriss and Boulanger, the liquefaction parameters were calculated (2014).…”

“…According to the method in Idriss and Boulanger, the liquefaction parameters were calculated (2014). According to the findings, there is saturated loose to medium-density sandy, silty clayey soil between 1.5 and 4.5 meters beneath the surface, and the liquefaction safety factor is less than 1 [23]. The study by Abdullah and Aal (2021) was aimed at assessing and creating maps of Jeddah City's vulnerability to liquefaction in the Kingdom of Saudi Arabia.…”

Bangladesh is one of the world's most disaster-prone areas. The northwest region of Bangladesh is the most seismically active region. Dinajpur is the district closest to the Himalayan frontal thrust, making it the most vulnerable to earthquake-related liquefaction. Therefore, the in-situ parameters are used to assess the liquefaction susceptibility of the subsurface geology for the Dinajpur district in terms of soil liquefaction safety factor (FS), the liquefaction potential index (LPI), and the liquefaction probability (PL). This study used deterministic and probabilistic techniques to estimate the liquefaction susceptibility of the area based on standard penetration test (SPT) N values. SPT data was collected at 160 different places within the study area. In an earthquake scenario with Mw = 6.5, liquefaction resistance is evaluated at each location using a 0.20g peak ground acceleration (PGA). The results of the SPT-based liquefaction assessment techniques were found to be considerably different. The soil strata prone to liquefaction in different zones of the city have been determined based on a common comparison. According to deterministic and probabilistic techniques, it has been found that, out of 160 locations, 36 and 50 sites are susceptible to liquefaction. Then, using geospatial techniques (IDW interpolation), hazard maps were created depending on the potential for liquefaction of particular locations. Finally, using an independent secondary dataset, the resulting hazard maps were validated to examine the developed approach. The obtained R2values for each regression analysis event were more than 0.79. Therefore, the produced hazard map may be utilized successfully for planning, management, and long-term development of the studied locations. Doi: 10.28991/CEJ-2022-08-07-010 Full Text: PDF

“…Only the average safety factor for the site can provide valid liquefiable soil depth information. Another case study was conducted by Wadi et al (2021), which followed similar steps by investigating the data from 28 boreholes with SPT measurements. The authors reported that saturated subsurface clay and silt soil up to a depth of 4 m had a low factor of safety (FS) value, which caused liquefaction risk for a designed 7.5 Mw earthquake located in Nigeria's Upper Benue region.…”

This study proposes an improved and precise liquefaction risk index for the evaluation and translation of outcomes into maps to establish susceptible liquefiable areas. Cyprus is the third largest and populated island in the Mediterranean Sea, which is rapidly expanding in every way. Significant infrastructures, such as hotels, educational institutions, and large residential complexes are being built. Historically, two major earthquakes with magnitudes of 6.5 Mw struck the island in 1953 and 1996. Potential liquefaction areas have been detected on the island's east coast as a result of these significant earthquakes. In this case study, the liquefaction potential of Tuzla and Long Beach in the northern part of Cyprus is estimated using the standard penetration test (SPT) data from more than 200 boreholes at different locations at the sites. The overall results are presented in a liquefaction risk index obtained from the factor of safety (FS) coefficient. It is clear that both study areas are susceptible to liquefaction. Thus, risk index maps are prepared to identify susceptible liquefiable areas. In addition, the average factor of the safety line was introduced for both sites to create a correlation between the liquefaction risk area and FS values of every borehole. It is clear that the adopted approach precisely provides the suspected depth of the liquefiable soil layer when compared with the risk index maps. Additionally, the results prove that the liquefaction potential must be considered during the design stage of new infrastructure in these areas.
