Forensic Assessment on Near Surface Landslide Using Electrical Resistivity Imaging (ERI) at Kenyir Lake Area in Terengganu, Malaysia

Analysis of Geotechnical-Assisted 2-D Electrical Resistivity Tomography Monitoring of Slope Instability in Residual Soil of Weathered Granitic Basement

“…In Peninsular Malaysia, shallow landslides are common occurrence that have been studied using 2-D ERT as reported by several researchers (Abidin et al, 2017;Ismail and Yaacob, 2018;Nordiana et al, 2018a;Nordiana et al, 2018b). However, a reliable method to include density in geotechnical calibration of ERT model resistivity values distribution is still rare.…”

“…Slope movement events that resulted in landslide have wrecked severe havoc and damage to lives and infrastructures with an estimated loss of several billions of dollars across the world (Chandarana, 2016;Sidle and Bogaard, 2016;Winter et al, 2016;Soto et al, 2017;Wang et al, 2017;Bordoni et al, 2018;Di Traglia et al, 2018;Tomás et al, 2018;Moragues et al, 2019;Yang et al, 2019;Kirschbaum et al, 2020). The impact of damages caused to lives and infrastructure as well as mitigation and management of this natural hazard has been the subject of research for decades (Abidin et al, 2017;Bordoni et al, 2018;Pasierb et al, 2019). However, research work on the area of slope instability monitoring to predict future occurrence of landslide to prevent loss of lives and properties has not yet been fully demonstrated (Chae et al, 2017;Intrieri et al, 2019;Park et al, 2019).…”

“…To adequately obtain information about the soil-water conditions in the subsurface structure, a noninvasive geophysical technique of ERT has been adopted by several researchers (Brillante et al, 2015;Giocoli et al, 2015;Hübner et al, 2015;Abidin et al, 2017;Angelis et al, 2018;Boyle et al, 2018;Cavalcanti et al, 2018;Gaffney et al, 2018;Gunn et al, 2018;Olabode and Ocho, 2018;Tomás et al, 2018;Pasierb et al, 2019). It provides a very fast, cheap, and efficient survey technique to characterize landslide-prone slopes (Pasierb et al, 2019).…”

Solution of Collinearity Problem in Two-Dimensional Electrical Resistivity Tomography using Wenner Array

“…Therefore, to address these drawback, multidisciplinary research across the engineering, physical and social sciences is required (Fragaszy et al, 2011). Thus, geophysical methods offer solution to some of the inherent challenges in borehole exploration method (Abidin et al, 2017) Among the advantages of geophysical techniques are; fast data acquisition, low cost and ability to cover a large area (Cosenza et al, 2006;Godio et al, 2006) As reported by Griffiths and Barker (1993), the electrical resistivity method is one of the most often used geophysical methods for subsurface investigation. Over time, the technique had witnessed great improvement in terms of availability of forward modelling and inversion schemes, efficient data acquisition and processing techniques (Ingeman-Nielsen et al, 2016;Rucker et al, 2012).…”

Shear joints and its relations with subsurface structures in Batu Melintang, Jeli, Kelantan, Malaysia

“…The researched found that 2D electrical resistivity surveys (ERI) provide a more detailed subsurface structure as it provides a more detailed interpretation compared to 1D electrical sounding (VES). In Malaysia, several previous researched conducted the application of resistivity method for subsurface structure investigation especially geohazard assessment such as landslide and sinkhole, e.g., (Bakhshipour et al, 2013, Abidin et al, 2017, Rauff et al, 2020. The assessment of detailed subsurface structure helps to avoid the dangerous geological hazards in the future as the accuracy assessment at 95% confidence level (Arisona et al, 2020).…”
