Local site effect is an important feature of seismic hazards, which often causes amplification of ground motions and results in increasing the damage potential of earthquake. This paper presents an experimental study of microtremor data to investigate the dynamic characteristics of soil and structures at the 15th May City, southeast Cairo, Egypt. This city was constructed on Eocene sedimentary rocks ... Read more

Lack of pressure data and/or one curve of the essential well logs such as density, neutron, sonic, resistivity and gamma ray curves in some reservoirs, is not preferred situation for the petrophysict, which will affect the petrophysical evaluation process and the reservoir characterization study. Four wells (A, B, C and D), in the area of interest, penetrated Baba sandstone zone ... Read more

Land reclaimed from water bodies or its equivalent (swamp, flood zones and abandon river channel) usually contain certain mechanically unstable geological formations (e.g. peat and clay) which are inimical to the foundation of engineering structures. Concerted effort must therefore be ensured to determine depth to competent layer (bedrock) across the proposed site as against conventional geotechnical test which is a ... Read more

The aim of this study is to delineate the areal extent of and estimate depths to a basaltic intrusion –Fahdi domal structure (FDS) – in the western desert of Egypt. The study also shed light on the different phases of deformations associated with this intrusion. For this purpose, we integrate total field ground magnetic data and aeromagnetic data, collected for ... Read more

This technique was originally proposed by Nogoshi and Igarashi (J Seism Soc Japan 24:26–40, 1971) and modified by Nakamura (Railway Tech Res Inst (RTRI) Q Rep 30:25–33, 1989). Read more
