Movimientos verticales recientes en Cataluña a partir de nivelaciones de precisión

Abstract

To determine recent vertical movements (R.V.M.) from precise leveling data we have compared the original height differences recorded in the field by the Instituto Geografico Nacional in two different campaigns. The accuracy, number of releveled bench marks and leveling paths of the two campaigns are adecuated to measure R.V.M.. The two studied profiles show significatives R.V.M.. Two steps of about 150 mm ± 30 mm, in 37 and 38 years (4 mm/year of relative velocity), which have, partially, tectonic origin has been obtained
