El análisis de los procesos de subsidencia representa la reducción de volumen de una unidad en el subsuelo. Esta reducción puede deberse a imperfecciones constructivas, consolidación de rellenos, disolución de evaporitas o el colapso de materiales limosos. En muchos casos, las evidencias superficiales, patologías, pueden permitir la caracterización del origen, pero éstas son dependientes de la reología de los materiales. La caracterización geométrica del subsuelo por medio de georradar, se presenta como metodología eficaz para identificar el radio real de los procesos activos, la identificación de la cota de afección y la cartografía indirecta de medios inestables en medios urbanos. Subsidence processes commonly imply volume reduction of an underground unit. This reduction can be due to constructive imperfections, filling consolidation, evaporitic solution or collapses of silty units. In many cases, the surficial evidences -pathologies- allow the identification of their origin even though they are contingent on the material rheology. The geometrical characterization of underground materials by means of Ground Penetrating Radar (GPR), is presented as a successful methodology for the actual determination of active processes radii, the identification of the origin depth and the indirect mapping of unstable areas at urban areas.
