... developed in contrast to those found in other humid tropical regions (Irfan, 1999). A series of chemical analyses, petrographical analyses and magnetic susceptibility tests of volcanic rock samples were carried out. These samples were collected at about 1m intervals within each of four boreholes (D01, D04...

.... Due to high water table and dense over-burden, sampling in boreholes has been difficult. In-situ tests like dynamic cone penetration tests (DCPT), plate load tests (PLT) and pressuremeter tests (PMT) were also conducted to evaluate the soil parameters. With the accumulation of data and understanding...
