Abstract: In Serra do Mar periodically are verified some events of landslides from scarped hogbacks. The landslides are inherent to the this region, propitiated by intensive bad weather, simultaneously associated to the other events occured in geological time, as the successives marine ingressions and regresses in the Quaternary period. As a consequence of this events, there is a load of settling dregs situated on Ubatuba's Coastal Plain, which is classified as "pocket beach", a small zone of settling dregs, separated by advances of bedrock, making the area of discontinuous sedimentation. This work has the objective to identify areas of marine deposits, submerged in the last marine ingression (occurred about five thousand years ago) with an elevation of about five meters related to the actual and the relation with the gravitational dregs situated on the Sedimentary Plain. It was verified the evolutions of marine levels along the Holoceno, as well as the typology and morphology of its sedimentation. It was simultaneously verified the occurrence of landslides and the occurrence of a slide down and its correlative dregs over the marine plain. Thus, the risks to the occupation of the area are very relevant, especially in rugged areas, close to hills and rivers.
