Las principales líneas de investigación son: 1) captura remota de datos geológicos; 2) modelización 3D de la estructura geológica del terreno; 3) caracterización, auscultación y modelización de los mecanismos de rotura de macizos rocosos y formaciones superficiales (en particular, deslizamientos, flujos torrenciales y desprendimientos rocosos); 4) evaluación de la peligrosidad, vulnerabilidad y riesgo; 5) desarrollo de sistemas de alerta temprana y alarma de fenómenos de origen geológico.

The group performs research on the analysis, monitoring, and modelling in engineering geology focussing on the analysis of the characteristics and behaviour of the rock masses, and on the evaluation of geological risks. The main research interest is: 1) application of remote sensing techniques for the capture of geological data; 2) 3D modelling of the ground; 3) characterization, monitoring and modelling of failure mechanisms of the rock masses and surficial formations (particularly, landslides, torrential processes, and rockfalls); 4) hazard, vulnerability and risk assessment; 5) design of early warning and alarm systems of geological processes.
