It is important to study in depth the morphostructural characteristics involved in underwater volcanism in order to understand the evolution of these volcanic centers with respect to their tectonic environment. Particularly, this study focuses on the Mount Orca submarine volcano, which is located at the Bransfield Strait (Antarctica), facin King George Island, and whose volcanic build reaches 650m high over a platform at 1340m deep, although the tectonic framework of the area is quite interesting, the interaction between three plates (Nazca, Scotia and Antarctic), the structural system that controls volcanism in unknown, mainly due to technological limitations or difficulty of access. This work presents a preliminary characterization of the morphology and structures associated with this underwater mount, through the digital elevation models obtained during the ANTARXXVI campaign with an ...
