It has now been well established that the depth of bedrock is a key parameter in assessing the impact of local site conditions on seismic hazard analysis. Where conventional geotechnical testing like standard penetration test (SPT) or cone penetration test (CPT) requires a far greater cost and manpower to be used for such purposes, geophysical testing like ground-penetrating radar (GPR) and mul...

detection of subsurface structures by means of gravity method can be used to determine mass distribution and density contrast of rock units. this distribution could be detected by different geophysical methods, especially gravity method. however, gravity techniques have some drawbacks and can't be always successful in distinguishing subsurface structures. performance of the gravity technique co...

Egypt’s mineral resources are an effective means of raising the country’s income. Consequently, searching for deep subsurface ore deposits is essential. In this study, we map structure and occurrence related gold-ore mineralization in ophiolitic-assemblage rocks around Wadi El-Saqia area Central Eastern Desert Egypt. Our approach combines airborne geophysical data (aeromagnetic mapping) geochem...

An integrated geophysical survey using both the electrical resistivity tomography (ERT) and groundpenetrating radar (GPR) methods was undertaken over a cave of great archaeological interest in southern Italy. The survey was performed to assess the stability of the carbonate rock roof of the cave. A geophysical survey was preferred to boreholes and geotechnical tests, in order to avoid the risk ...

The Easternmost Mediterranean is a transition region from the ocean to continent where spreading and collision zones of lithospheric plates join. methodology paleomagnetic mapping based on combining geological geophysical techniques for continental oceanic platforms: magnetic data interpretation, reconstructions, results magnetized rock radiometric dating, satellite analysis, tectonic–structura...

A series of digital data sets were compiled for input into a geophysical data base for a one degree quadrangle in Arizona. Using a Landsat digital mosaic as a base, information on topography, geology, gravity as well as Seasat radar imagery were registered. Example overlays and tabulations are performed. The role of remote sensing in environmental inventory has evolved into an important supplem...

In 2001, the Antarctic Digital Magnetic Anomaly Project produced ADMAP-1 compilation that included first magnetic anomaly map of region south 60◦S. To help fill ADMAP-1’s regional coverage gaps, international geomagnetic community from 2001 through 2014 acquired an additional 2.0+ million line-km airborne and marine data. These new data together with surveys were not previously in public domain...

Spatial planning aims at constantly improving the distribution of people and activities within available space, especially near cities on ancient agricultural or industrial areas. However, a proper schedule development work necessitates assessment, as precisely possible, difficulties that would be encountered in terms geotechnical abilities terrain hazards resulting from previous use. In Grands...

Lightning mapping technology has proven instrumental in understanding lightning. In this work we present a pipeline that can use lightning observed by the LOw-Frequency ARray (LOFAR) radio telescope to construct a 3D map of the flash. We show that LOFAR has unparalleled precision, on the order of meters, even for lightning flashes that are over 20 km outside the area enclosed by LOFAR antennas ...
