SIGMA-3D software package of structural interpretation is an effective tool for the automated three-dimensional modeling while studying magnetic anomalies created by underwater volcanoes. With the help of this software package submarine volcanoes Grigorieva, Krylatka, and Yubileiny, located in the Kurile island arc, have been studied.
