Australian Plate south, is now being torn apart along the transform boundary marked by the Alpine Fault. South of New Zealand the boundary becomes a transitional transform-convergent boundary, the Macquarie Fault Zone, where the Australian Plate is beginning to subduct under the Pacific Plate along the Puysegur Trench. Extending southwest of this trench is the Macquarie Ridge. The southerly side is a divergent boundary with the Antarctic Plate called the Southeast Indian Ridge (SEIR). The subducting boundary through Indonesia is not parallel to the biogeographical Wallace line that separates the indigenous fauna of Asia from that of Australasia. The eastern islands of
Inter-Entity Boundary Line Inter-Entity Boundary Line The Inter-Entity Boundary Line (, ), commonly abbreviated IEBL, divides Bosnia and Herzegovina into two entities, the Republika Srpska and the Federation of Bosnia and Herzegovina. The total length of the Inter-Entity Boundary Line is . Along the IEBL is the 2 km Zone of Separation, which stretch toward both entities, making the Zone 4 km wide in total. The IEBL essentially runs along the military front lines as they were at the end of the Bosnian War with some major adjustments (most importantly in the western part of the country, and in and around Sarajevo), made
