Abstract
La deformación del terreno es un fenómeno físico que se origina como consecuencia de diferentes procesos, tanto de origen natural (p.e., erupciones volcánicas, terremotos o deslizamientos de ladera) como de origen antrópico (p.e., la inyección o extracción de fluidos o como resultado de explotación minera). El rápido crecimiento de la población mundial, así como su mayor demanda de recursos naturales provoca que, inevitablemente, la sociedad sea más vulnerable ante estos peligros. Una correcta detección y monitorización de estos fenómenos de deformación resulta esencial para poder comprender y caracterizar su origen permitiendo así estudiar su evolución temporal con detalle. Esto hace posible planificar una gestión sostenible de los recursos naturales y ayuda en la toma de decisiones en situaciones de crisis. Actualmente existen dos técnicas geodésicas ampliamente utilizadas para el control de deformación superficial: los Sistemas Globales de Navegación por Satélite (GNSS) y las técnicas de Interferometría Radar de Apertura Sintética (InSAR). Las técnicas GNSS permiten un posicionamiento preciso sobre la superficie terrestre proporcionando información de las tres componentes del desplazamiento (x, y, z) con una gran resolución temporal, pero normalmente, una baja cobertura espacial. Las técnicas InSAR, permiten obtener el desplazamiento de la superficie en un vector unidimensional, conocido como Línea de Visión (abreviado LOS en inglés), con una alta precisión y resolución espacial, pero menor resolución temporal...
Surface deformation can be the consequence of different processes, both of natural origin (e.g. volcanic eruptions, earthquakes, or landslides) and of anthropogenic (e.g. injection or extraction of fluids or as a result of mining). The rapid growth of the world's population, as well as its increased demand for natural resources, inevitably makes society more vulnerable to these hazards.The correct detection and monitoring of these surface deformation phenomena are essential to understand and characterize the mechanisms that cause them allowing to study their time evolution. It helps decision making during crisis as also to improve the sustainable management of natural resources There are currently two widely used geodetic techniques for surface deformation monitoring: Global Navigation Satellite Systems (GNSS) and Interferometric Synthetic Aperture Radar (InSAR) techniques. GNSS techniques enable precise positioning on the earth's surface, providing information on the three components of displacement (x, y, z) with high temporal resolution but typically limited spatial coverage. InSAR techniques allow obtaining the surface displacement in a one-dimensional vector, known as Line of Sight (LOS), with high precision and spatial coverage but lower temporal resolution...
