  Seismic refraction method has been used to map the near surface geological features in parts of the Oru Area. Ten seismic refraction profiles were surveyed within the Area. The instruments used were a 10 kg sledge hammer, Mark 6 digital 12-channel seismograph, Reflexw software was used to process the seismic data. A GPS system was used to obtain the co-ordinates of the profiles. Surfer 11 software was used to produce contours of the seismic velocities within the study Area. This research has established that the distribution of p-wave velocities within the subsurface of this area show a general increase of velocity with depth and velocity varying from 400 m/s to 770 m/s for the weathered layer. The thickness of the weathered layer is on the average 20.4 m. Field mapping shows that the Northern part of the study area rests on Ogwashi-Asaba formation. The area has mudstone, claystone, g..
