LONDONO-LINARES, Juan Pablo. Landslides susceptibility assessment using discriminant analysis. Application on a regional scale. Dyna rev.fac.nac.minas [online]. 2017, vol.84, n.201, pp.278-289. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v84n201.61385.

In this article, we present the stepwise application of the quantitative multivariate method known as Discriminant Analysis to obtain models of susceptibility to landslides at regional scales. As a proposal, context variables were incorporated into the analysis, which aim to account for anthropogenic action within the territory. The detailed procedure is presented, applied to a specific area, obtaining five susceptibility functions, which are analyzed in terms of performance to select the best model. In conclusion, adequate values of performance of the models are obtained, confirming the usefulness of the method as an initial step in the calculation of landslide risk at regional scale for land planning.
