The multi- faceted nature of these influences makes the surveillance of mass movements a highly intricate task, requiring an understanding of numerous interdepen- dent variables. Recent years have seen an emergence in scholarly research aimed at integrating geophysical and geotechnical methodologies. The con- joint examination of geophysical and geotechnical data offers an enhanced perspective into subsurface structures. Within this work, a methodology is proposed for the synchronous analysis of electrical resistivity geophysical data and geotechnical data, specifically those extracted from the Light Dy- namic Penetrometer (DPL) and Standard Penetration Test (SPT). This study involved a linear fitting process to correlate resistivity with N10/SPT N-values from DPL/SPT soundings, culminating in a 2D profile of N10/SPT N-values How to cite this paper: Bortolozo, C.A., Mendes, T.S.G., Motta, M.F.B., Simões, S.J.C., Pryer, T., Metodiev, D., de Andrade, M.R.M., de Moraes, M.V., de Paula, D.S., Bastos, N.J., Pampuch, L.A., Mendes, R.M. and de Moraes, M.A.E.
