Abstract—An integrated approach involving Electrical Resistivity Tomography (ERT), Vertical Electrical Sounding (VES), and Very Low FrequencyElectromagnetic (VLF-EM) methods has been used to map the concentration and pathway of leachates plumes beneath Laka dump site in OgbomosoSouthwestern Nigeria. In-situ analysis, specifically, Electrical Conductivity (EC) and Total Dissolved Solids (TDS) were also carried out on water samplescollected from hand dug wells, bore holes and stream around th...
ABSTRACTThis study is aimed at using the characteristics of polluted soil to delineate different soillayers and deduce ways of providing remediation to the problems generated as aresult of soil pollution using Electrical Resistivity Method.An inversion of the measured apparent resistivity values using a computer program was carriedout to determine the true subsurface resistivity. This method was used toestimate the lateral and vertical extend to which a particular soil has beencontaminated by...

ABSTRACTThis study reviews earthquake monitoring and sensing in Nigeria. The techniques used to monitor earthquakes include seismic, Global position system (GPS) and remote sensingmethods. For now there is no scientific method of predicting earthquakes, butseismologists depend on the anomalous animal behaviour, radon emissions,trends, creep fault, drop/rise in the water level and anomalous plant behaviourfor earthquake prediction. The study also revealed that Nigeria is not seismicallyfree fr...
ABSTRACTThis research assesses the various factors responsible for road failures in thesouthwestern and south-southern parts of Nigeria with the aim of reportingfindings to the public domain. The research further stressed the importance andrelevance of geophysics in evaluating civil engineering structures such asroads. The above goals were met by studying the results of surveys carried outby researchers in southern Nigeria. Electrical Resistivity and Electromagneticmethods have been used to e...
The aim of this work is to describe various form and sources of electromagnetic radiation and its effect on earth.INTRODUCTIONElectromagnetic radiation (EM radiation or EMR) is a fundamental phenomenon of electromagnetism, behaving as waves and also as particles called photons which travel through space carrying radiant energy. In a vacuum, it propagates at the speed of light, normally in straight lines. EMR is emitted and absorbed by charged particles. As an electromagnetic wave, it has both...
