“…The layer below the groundwater table can be considered as the slip surface of the landslide (Drahor et al, 2006). Hence, the boundary between upper unconsolidated deposits with low resistive groundwater table and below high resistive hard, sound and unweathered bedrock can be considered as the slip surface in this study (Havenith et al, 2000;Batayneh and al Diabat, 2002;Demoulin et al, 2003;Asriza et al, 2017). The depth of this slip surface in this landslide varying between 10 m and 30 m with average depth at 25 m at the crown and 10-20 at the main body part and more than 50 m toward the toe area.…”

“…Similarly, the study of geological features in a landslide by using the geophysical method provides an useful technique (Konagai et al, 2005). Asriza et al (2017) used the ERT survey and other laboratory analyses to identify the location of the slip surface for the stability of a landslide. The variation of apparent resistivity in-depth-wise and identifying the saturated zone was investigated by the ERT survey (Kim et al, 2009).…”

The depth of the slip surface and thickness of the overburden deposit play a major role in assessing the slope stability of a landslide. Electrical Resistivity Tomography (ERT) survey was carried out in the Taprang Landslide, Kaski district, west- central Nepal to determine subsurface lithological conditions, depth and geometry of the slip surface. Wenner and dipole- dipole arrays were mainly applied in this ERT survey. The electrical resistivity survey revealed that there is a wide range of resistivity value which shows different kinds of layers in the subsurface, and the boundaries between these layers played a significant role to identify the slip surface. The data show mainly three layers from surface to bottom. An upper layer represents the dry to saturated colluvium and sandy gravelly soil (500 to 8000 Ωm), the middle layer is highly –saturated soil with low resistivity value (100–700 Ωm) and unweathered fresh bedrock of schist and quartzite with high resistivity value (1000 to 8000 Ωm) at the bottom layer. The slip surface is considered as depth 25 m at the crown, 10–20 m at the main body part, and below 50 m at the toe and curved in geometry which indicates the rotational type of landslide. Investigation of the slip surface in a landslide using the ERT survey aids to know the slope stability.

“…The most outstanding conferences tackled topics of liquefaction [202][203][204], disaster waste [205,206], and landslides [207][208][209]. An amount of 7.42% corresponded to proceedings papers, with 97 documents highlighting landslides [110,210,211] and earthquakes [212][213][214][215], while 2.97% were books e.g., [216]; chapters of books, e.g., [156,217]; data papers [218]; notes [219]; reviews [220]; editorials [221], and short reviews, e.g., [222,223].…”

A Systematic Review of the Relationship between Geotechnics and Disasters

Landslides, earthquakes, and other natural events can change the landscape and generate human and economic losses, affecting transportation and public service infrastructure. In every geotechnical project, the investigation phase plays a fundamental role in reducing the risk of occurrence and mitigating catastrophes. As a result, governments have created entities to study disasters and identify triggering factors that generate huge losses worldwide. This research aims to conduct a systematic review of the relationship between geotechnics and disasters through bibliometric techniques, scientific production evaluation, and case studies analysis to recognize key topics, methods, and thematic development of the research worldwide. The research methodology consisted of three steps: (1) Database analysis, selection, and combination, (2) bibliometric analysis, and (3) systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. The systematic review with bibliometric analysis collected data from 1973 to 2021, with 1299 academic publications indexed in the Scopus and WoS database. These results indicated a growing trend of annual publications on disasters and their relationship with geotechnical studies, highlighting current issues and technological innovation. The main research trends in disaster risk assessment were topics mainly linked to landslides, earthquakes, liquefaction, and inappropriate analysis models with applications of geophysical methods, laboratory tests, remote sensing, and numerical models.

“…At a depth of 6.31 -39.8 m, it is dominated by sand clay too. The boundary between the medium resistivity zone and the low resistivity zone is regarded as a slip surface [18]. It can be view at the black lines with a depth of 19.95 -31.62 m. There is a difference in the resistivity value which can be assumed to be a slip surface.However, on line 7 there is clay up to a depth of 39.8 m. The type of rock that may be a slip surface is clay [19].…”

Landslides can be occurred in almost every natural slope or artificial slope slowly or suddenly with or without any prior signs. The main reason for slope collapse is the increase in shear stress in the landslide, the decrease in shear strength, or both. Landslide problems can result in loss of life and property, damage to the environment, infrastructure, public facilities, and disrupt livelihood generally. Landslides can be detected by exploration of the subsurface. The geoelectrical method is one of the geophysical methods to know the change of resistance of a type of rock layer below ground level. The research aims to interpret the lithology of the subsurface in the Candi Industrial Area, Ngaliyan, Semarang using Schlumberger configuration. The results of measurements are voltage and electric current to calculate the apparent resistivity value processed by IP2Win software to determine the lithology and the slip surface area. The results present that lithology in the research area consists of sand clay, clay, and sandstone. The results showed that the locations of landslide-prone areas lie at the contact between sand clay and clay with that area at a depth of between 19.95 – 31.62 m there is one difference in the resistivity value which can be assumed to be a slip surface.The result of the research can be used to make policy rules of landslide mitigation.
