El grup fa recerca en l’anàlisi, monitorització i modelització en enginyeria geològica, especialment l’anàlisi de les característiques i comportament dels massissos rocosos i l’avaluació de riscos geològics. Les principals línies de recerca són: 1) captura remota de dades geològiques; 2) construcció de models 3D del terreny; 3) caracterització, monitorització i modelització de la ruptura de massissos rocosos i de formacions superficials (en particular, esllavissades, fluxos torrencials i despreniments rocosos); 4) avaluació de a perillositat, vulnerabilitat i el risc; i 5) desenvolupament de sistemes d’alerta primerenca i d’alarma de fenòmens d’origen geològic.

El grupo realiza investigación en el análisis, auscultación y modelización en ingeniería geológica, especialmente el análisis de las características y el comportamiento de macizos rocosos y la evaluación de riesgos geológicos. 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.
