在印度尼西亚苏门答腊-安达曼地震及其海啸造成大量生命损失之后，邻近的巽他海沟俯冲带可能发生触发地震是一个真实的关切。我们已经计算了同震应力的分布在这个区域，以及在相邻的，垂直走滑苏门答腊断层，并发现在这两个结构，显着提高了已经相当大的地震危险，由他们构成的应力增加。特别是，该区域发生大规模俯冲带事件的可能性增加，并伴随着发生另一次海啸的危险，因此更加迫切需要在印度洋建立海啸预警系统。
Following the massive loss of life caused by the Sumatra–Andaman earthquake in Indonesia and its tsunami, the possibility of a triggered earthquake on the contiguous Sunda trench subduction zone is a real concern. We have calculated the distributions of co-seismic stress on this zone, as well as on the neighbouring, vertical strike–slip Sumatra fault, and find an increase in stress on both structures that significantly boosts the already considerable earthquake hazard posed by them. In particular, the increased potential for a large subduction-zone event in this region, with the concomitant risk of another tsunami, makes the need for a tsunami warning system in the Indian Ocean all the more urgent.
