El Grupo de Volcanología de Barcelona lleva a cabo estudios de volcanología física en zonas de particular interes de España como por ejemplo las Islas Canarias, Cabo de Gata y Cataluña (Zona volcánica de la Garrotxa y Pirineos). Asimismo, estos estudios se extienden a áreas tales como Méjico, Costa Rica, Italia, etc. Dentro del marco de estudios de volcanología física, se realizan estudios estratigráficos y sedimentológicos, mapas geológicos y geología estructural. El objetivo de esta línea de insvestigación es mejorar los conocimientos científicos de los miembros del grupo en referente a los procesos eruptivos y más concretamente al estudio de las calderas de colapso. Estos estudios sobre volcanología física incluyen los conceptos más actuales sobre modelos numéricos y evaluación del peligro volcánico comentado en otros apartados.

Los resultados obtenidos en esta línea de investigación complementa los resultados anteriores mediante métodos de petrología experimental y estudios de tiempos de residencia de magmas. El objetivo principal es caracterizar las condiciones necesarias para el desarrollo del volcanismo explosivo. Los estudios incluidos en el marco de la petrología y geocronología realizados por el Grupo de Volcanología se desarrollan básicamente en el laboratorio de procesos geológicos SIMGEO. Las escalas de tiempo y las tasas de los procesos magmáticos son una importante fuente de información a la hora de comprender diversos aspectos de la actividad ígnea. Por ejemplo,el tiempo de vida de los magmas localizados debajo de calderas o volcanes activos puede llegar a condicionar los flujos, tanto de masa como de temperatura, relevantes en la explotación geotérmica y la evaluación del riesgo volcánico. En el Grupo de Volcanología de Barcelona determinamos la duración de dichos procesos a través de la modelización (utilizando la Ley de Fick para la difusión) del re-equilibrio por difusión de los isótopos y elementos en diversos minerales.
