Southeast (SE) Asia is surrounded by subduction zones causing intense seismicity and volcanic activity. Subduction has been the principal tectonic driver of collisions that caused the growth of continental SE Asia, and most recently the collision of Australia with SE Asia. The western part of SE Asia, Sundaland, is a heterogeneous and weak region, reflecting processes that can be observed today in the east, where there are subduction zones in different stages of development. A close relationship between subduction rollback and extension has caused dramatic elevation of land, exhumation of deep crust, and spectacular subsidence of basins, observable with remotely acquired images and seismic and multibeam data obtained from oil exploration. New dating indicates that subsidence and uplift occurred at high rates during short time intervals. Laboratory studies, modeling, and reconstructions provide valuable insights, but field-based studies continue to present surprises and new discoveries essential for interp...

东南亚：马来群岛地质新观点

东南亚 (SE) 被俯冲带包围，导致强烈的地震和火山活动。俯冲一直是导致东南亚大陆增长的碰撞的主要构造驱动力，以及最近澳大利亚与东南亚的碰撞。东南亚西部巽他兰是一个异质弱的地区，反映了今天在东部可以观察到的过程，那里有不同发展阶段的俯冲带。俯冲回滚和伸展之间的密切关系导致了陆地的显着抬高、深部地壳的剥脱和盆地的壮观下沉，这些可以通过远程获取的图像以及石油勘探获得的地震和多波束数据进行观察。新的测年表明，在很短的时间间隔内，沉降和隆升发生率很高。
