Comment on Shear wave reflection seismic yields subsurface dissolution and subrosion patterns: application to the Ghor Al-Haditha sinkhole site, Dead Sea, Jordan by Polom et al. (2018)

Abstract

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.
