We present a study on the mud volcanoes of Bolle della Malvizza located in the Irpinia sector of the southern Apennines (southern Italy). These structures are hosted in the Upper Cretaceous-Upper Miocene Fortore succession (Lagonegro-Molise Basin) and emit mud and bubbles of methane and CO2. Mud volcanoes are focused in a narrow area of ca. 5000 m2, consisting of eight main emission centres and several minor craters. We approached this research with a multidisciplinary study, including stratigraphic and structural surveys, geophysical and geochemical investigations and morphometric analyses. This study aims to investigate the origin of fluid migration and shed light on the pathways mainly controlled by faults.
