The Krakatau project has been launched as a regional study along the Indonesian island arc aiming at understanding the response of an island arc and of its fore-arc to an increased obliquity in the convergence along its subducting border. Along the Sunda island arc, convergence varies from near-to-normal along Java to increasingly oblique along Sumatra, and to near-to-tangent along the Andaman-Nicobar ridge. As a result of this increased obliquity, it has been assumed that the fore-arc region has been mobilized, as a whole as a series of segmented units with a resulting strike-slip motion parallel to the island-arc.
