抽象。印度尼西亚群岛以沿着巽他弧发生灾难性地震引发的海啸而闻名。然而，与海底滑坡有关的海啸危险尚未得到充分解决。在本文中，我们汇编了已知的海啸事件，滑坡参与是肯定的，并总结了出版的滑坡的地球物理方法确定的属性。我们描绘了新的质量运动，发现在新的测深，并确定其关键参数。使用数值模拟，我们计算可能的海啸情景。此外，我们提出了一种识别滑坡海啸的方法，使用一系列的几个浮标底部压力单位。
Abstract. The Indonesian archipelago is known for the occurrence of catastrophic earthquake-generated tsunamis along the Sunda Arc. The tsunami hazard associated with submarine landslides however has not been fully addressed. In this paper, we compile the known tsunamigenic events where landslide involvement is certain and summarize the properties of published landslides that were identified with geophysical methods. We depict novel mass movements, found in newly available bathymetry, and determine their key parameters. Using numerical modeling, we compute possible tsunami scenarios. Furthermore, we propose a way of identifying landslide tsunamis using an array of few buoys with bottom pressure units.
