“…The shallow seismic refraction technique is widely used in Egypt to infer the subsurface ground model, mapping bedrock depth, and in determination of elastic moduli and geotechnical characteristics with good and reliable results (e.g. Toni 2007Toni , 2012Toni et al 2013;Selim et al 2014;Basheer 2016).…”

The seismic hazard assessment for mitigating the seismic risk is an essential step before starting construction of a new settlement. One of the tools that could help in achieving this goal is the application of seismic refraction method for evaluating the geotechnical characteristics and dynamic properties of the soil deposits. Dynamic characteristics are fundamental for understanding the response of the soil under dynamic loading. Shallow refraction technique is in-situ test depends on the computation of seismic wave velocities which penetrating the soil. A total number of 88 compressional (P) and Shear wave (S) seismic refraction profiles have been conducted at the southern extension of Marsa Alam city on the Red Sea coast. The average Pand S-wave velocities were estimated for the subsurface layers consequently. Microzonation map for each layer was released by the spatial interpolation of data. In addition, the iso-thickness map was created for manifesting the soil thickness all over the studied area. Geotechnical parameters of the subsurface sediments were computed, as well as the zonation maps for density and Nvalue parameters have been created. The obtained maps emphasize that the first layer could be considered as foundation soil due to it is relatively stiffness.
