. To initiate the development of cone penetration resistance qc and shear wave velocity Vs correlations of soils from Indonesia, the results of mechanical cone penetration soundings and seismic downhole tests from Depok, West Java area are compiled and analyzed. The soils are predominantly silt-clay soils. The results of the tests are used to develop a qc – Vs correlation. The results and the associated correlation are then compared to qc – Vs correlations from other countries.
