Abstract. Seismic reflection S-wave technique is very effective and has demonstrated nice results in previous investigations of various authors. However, the salt layer was not detected in the Ghor Al-Haditha area (Jordan) because of some reasons. The main reason is that about ~ 80 % of reflection lines were carried outside the salt area delineated by Ezersky et al. (2013b) based on results of El-Isa et al. (1995). Other possible factor is too strong filtering of seismic data obtained from the upper part of the section (up to 50 m deep). Our and Polom (2018) assessment of the work of other authors diverges. We affirm that the salt layer of 7–10 m thickness is located at ~ 40 m depth in the Ghor Al-Haditha area.

“…5,in Polom et al). According to Ezersky et al (2013b) the seismic reflection Line 1b is generally located out 55 of the salt area. The southern part of this line is located some 200 m east of the salt area, whereas northern part is approaching to the subsidence and sinkholes area (location of this line is shown in Fig.…”

“…Geophysical methods of detecting voids in the rock mass have been found to be helpful in the assessment of sinkhole hazard, which was noted in the paper by Kaufmann (Kaufmann 2014). The work by Ezersky et al (Ezersky et al 2013) also exhibited the results of the research aimed at the assessment of the sinkhole formation hazard. The research, conducted by means of SRFR, ERT and gravimetric methods, was positively verified by drilling boreholes.…”

Sinkholes forming as a result of loss of stability of shallow voids of natural or anthropogenic origin (mining activity) pose a serious hazard to buildings and infrastructure and especially to the inhabitants of the area. The paper presents an example of the verification of the author's mathematical model of forecasting the formation of sinkholes. The verification was performed with the use of a computer program for a case that was strictly compliant to the model assumptions. The sinkhole has formed above a working located at the depth of 54 m, outside the area of bifurcations or crossings with another gallery. The working was not influenced by mining exploitation, which means that the analysed case fully met the assumptions of the adopted mathematical model. The calculations of the sinkhole dimensions were also carried out, providing results that correspond to the actual conditions. The calculations and the performed analysis have confirmed the usability of the proposed model.

“…Ezersky et al . () used both these methods along with microgravity in the Dead Sea region to investigate the formation of sinkholes in association with the presence of a shallow salt layer.

“…There have been many deep exploration-scale seismic studies on salt dome and related structures in sedimentary basins and many ERT investigations of saltwater intrusion into coastal aquifers, but very few previous studies have used seismic refraction and/or ERT methods to image shallow terrestrial salt structures. Ezersky et al (2013) used both these methods along with microgravity in the Dead Sea region to investigate the formation of sinkholes in association with the presence of a shallow salt layer. Beneath the urban area of Hamburg in Germany, Kuhn, Ohrnberger and Dahm (2011) mapped the top of a shallow salt diapir with passive seismic measurements, while Krawczyk et al (2013) investigated sinkholes using an active shear-wave technique.…”

In the northeast of Thailand, many swamps and lakes show evidence of rock salt dissolution, with attendant environmental problems due to saline groundwater and soil salinization. The knowledge of the depth and structure of the rock salt would be useful to achieve a better understanding of the impact of its dissolution on the environment and to facilitate effective land management strategies. Geophysical methods can provide key subsurface information. Four seismic refraction profiles and three electrical resistivity tomography profiles were carried out between Nong Bo and Nong Pong reservoirs in the salt‐affected Borabue district of Maha Sarakham province. The seismic results indicate the top of shallow rock salt beneath Nong Bo reservoir as a diagnostic zone of high P‐wave velocity >3400 m/s at depths >20 m. The electrical resistivity tomography investigation shows electrical resistivity values ≳5 Ωm at similar depths, indicative also of shallow rock salt. Zones interpreted to be saline groundwater are electrically conductive, identified by electrical resistivity values ≲5 Ωm in the electrical resistivity tomography images. The combined seismic–electrical resistivity tomography interpretation suggests that shallow rock salt lies beneath the reservoirs and ponds in the Borabue district but does not appear to form a continuous body between the two largest reservoirs.
