dc.description.abstractAmbrym is an active volcanic island with 2 major vent complexes; Marum and Benbow. These vent complexes are continuously active over at least the past two thousands of years. These active vents either produce constant degassing during quite periods or sub-Plinian to Vulcanian explosive eruptions commonly influenced by magma-water interaction triggered phreatomagmatic explosive phases. The active vents of Ambrym perfectly expos inner walls of the crater/conduit transition zone, allowing to study in cross sectional view of the interbedded coherent magmatic bodies with pyroclastic successions. In the inner crater/conduit wall of the Marum volcano, that consists of at least 3 major vents, as well as a vent that is located on its flank (Niri Taten) exposes solidified complex lava lake cross-sections, lava spatter cone feeding lava pods, shallow intrusions as well as large sills that connected through a complex network of pathways to the surface and/or into the pyroclastic edifice of the volcano. This suggests that shallow level infiltration of melt into a mafic volcano plays an important role in the edifice growth.en_US
