“…In line with previous studies (Ahmed & Carpenter, 2003; Bernatek‐Jakiel & Kondracka, 2016; Bovi et al, 2020; Cardarelli et al, 2014; Giampaolo et al, 2016; Joshi et al, 2021; Leslie & Heinse, 2013; Patti et al, 2021), soil pipes in the study area are presented as zones of higher ER on the ERT profiles (Figure 8) because the air filling the pipes behaves as an insulator (Samouëlian et al, 2005). In the study area, ER above 268 Ωm indicates the zones affected by piping erosion, whereas clear pipes are marked by ER >427 Ωm (Figure 8).…”

“…In the study area, ER above 268 Ωm indicates the zones affected by piping erosion, whereas clear pipes are marked by ER >427 Ωm (Figure 8). For instance, Bovi et al (2020) in tropical humid forests in Brazil found zones with ER > 4000 Ωm to be soil pipes, and Joshi et al (2021) in the humid Western Ghats in India interpreted zones with ER > 1800 Ωm as soil pipes. On the one hand, this suggests that the general geophysical response of soil pipes is the same, that is, with higher ER values than the surroundings.…”

“…So far, various different geophysical methods have been explored in soil pipes detection, among which ground penetrating‐radar (GPR) (Bernatek‐Jakiel & Kondracka, 2016, 2019; Botschek et al, 2000; Got et al, 2014; Holden, 2004, 2006; Holden et al, 2002; Wodajo et al, 2021) and electrical resistivity tomography (ERT) (Ahmed & Carpenter, 2003; Bernatek‐Jakiel & Kondracka, 2016; Bovi et al, 2020; Cardarelli et al, 2014; Giampaolo et al, 2016; Joshi et al, 2021; Leslie & Heinse, 2013; Patti et al, 2021) have received the most attention. These methods were tested to detect and visualize soil pipe networks, as well as to recognize the factors controlling piping erosion.…”

Studying soil pipes is a methodological challenge that needs improvement in detection methods in order to better recognize the role of piping erosion in land degradation and hillslope hydrology. This study explores electromagnetic induction (EMI) and electrical resistivity tomography (ERT) in order to identify soil pipes. The study was conducted in a mountainous area (the Bieszczady Mountains, SE Poland) under a temperate climate, where pipes develop in silty-clayey soils. In the plot area, eight profiles were measured by the conductivity meter at different depths and then interpolated to present apparent electrical conductivity (EC a ). Also, six ERT profiles were carried out using the Wenner-Schlumberger electrode configuration. The EC a values measured by EMI are not very diversified, suggesting its lower sensitivity to changes in the EC a , whereas the EC a values measured by ERT are characterized by greater fluctuation, that is, better detection possibilities. ERT has revealed soil pipes as zones of higher electrical resistivity (ER >268 Ωm) than their surroundings (characterized below pipes by ER <105 Ωm) underlying the air filling of pipes (ER >427 Ωm), whereas EMI has revealed its higher sensitivity to water content. The EMI results have shown the lowering of the water table in the lower part of the slope, perhaps because of the drainage by a complex pipe network. EMI allows quick measurements of EC a providing information on water content, and thus indirectly soil pipes, but, it cannot delineate individual pipes. Only the integration of geophysical methods supported by field recognition provides an effective method to detect soil pipes.

“…Lithology plays a significant role in landslide generation (Joshi et al, 2018(Joshi et al, , 2021. In the weak lithology, clayey layers allow downward water movement and serve as the gliding plane for the overlying masses (Joshi et al, 2021). The core of Sikkim consists of unfossiliferous low-grade metasediments of Daling Group of rocks and sedimentary Gondwana Group of rocks, whereas these rocks enveloped by the gneiss rocks of Darjelling and Khangchendzonga formations, and granitic bodies of Chungthang Formation.…”

Sikkim, a north‐eastern state of India, has a very specific and unique place in the tourism map of India. Every year, lakhs of people visit the state. To accommodate such floating population in the area, some big towered home stays/hotels have been constructed. However, the area is under the threat of many natural disasters such as earthquake, landslide, land subsidence, cloudburst, etc. In the year 2021, within a span of 8 months (April–November), the Sikkim state hosted four light to moderate earthquakes (Mw 4.1–Mw 5.1). Out of these, the strongest earthquake (Mw 5.1) occurred on 5 April 2021, which was well experienced in the parts of Indian states (i.e., Sikkim, West Bengal, Bihar) and across International borders, viz Bangladesh, Nepal, Bhutan, and China. Fortunately, this earthquake did not cause any major damage in the region. However, in the last two decades, one moderate (Mw 5.3) and one strong earthquake (Mw 6.9) has occurred in the Sikkim region on 14 Feb 2006 and 18 September 2011, respectively. Both of these earthquakes caused well enough damage to the residential as well as commercial buildings. Apart from infrastructural degeneracy, the 2011 Sikkim Earthquake (Mw 6.9) also caused generation of co‐seismic landslides within ~100 km epicentral distance from the earthquake. After a decade, from the 2011 earthquake, Gangtok city and other parts of the state have been rebuilt and reconstructed again, but most of the newly constructed and old refurbished buildings are established in the steep slope areas without considering the geotechnical properties of the underlying soil. These structures could be vulnerable during moderate to strong earthquakes. Therefore, the present study unfurled a question “Did we learn any lesson from the 2011 Sikkim Earthquake?”. Furthermore, the study calls for earthquake hazard adaptation measures in the tectonically sensitive Himalayan region in order to safeguard the lives and vital infrastructure.
