Subsurface soil varies from place to place due to the rock type, its mineral constituents, the climate
 of the area, time and other geological activities such as meteorite impact. The process that leads to
 the formation of impact crater can cause great variation in the subsurface soil characteristics, which
 may have an effect on civil engineering structures. Hence, the need to evaluate the subsurface soil
 of the impacted area. In this study, Seismic refraction and borehole data were used to achieve the
 aim. The result revealed that the overburden layer inside the crater is dominated by low-velocity
 values (< 750 m/s) which correspond with low N-values. Moderate seismic velocity values (750 –
 1400 m/s) with moderate to high N-values were predominant for overburden soil within the crater
 rim and outside the crater. Slightly, moderately and highly weathered granite was observed at all
 survey lines with velocity values ranging from 1200 - 3450 m/s. The low N-values with lowvelocity values obtained inside the crater are indications that the subsurface soil inside the impact
 crater area has been deformed and weakened as evident by the presence of brecciation which
 occurred during the impact process.
