我们对新的水深测量数据的分析显示，在印度尼西亚爪哇中部和松巴岛之间的舜他东缘有六个海底滑坡。它们的体积从爪哇弧前盆地的1千米到松巴和松巴瓦附近海沟的20千米。我们通过模拟相应的海啸及其在附近海岸的抬头来估计每一次事件的潜在危险。有四个滑梯位于1977年发生海啸的SumbaMw=88.3地震的震中附近。然而，将记录在案的海啸启动高度和到达时间与我们的模拟结果进行比较，既不能证实也不能否认地震引发了这些海底山体滑坡的假设。
Our analysis of new bathymetric data reveals six submarine landslides at the eastern Sunda margin between central Java and Sumba Island, Indonesia. Their volumes range between 1 km³ in the Java fore-arc basin up to 20 km³ at the trench off Sumba and Sumbawa. We estimate the potential hazard of each event by modeling the corresponding tsunami and its run-up on nearby coasts. Four slides are situated remarkably close to the epicenter of the 1977 tsunamigenic SumbaMw= 8.3 earthquake. However, comparison of documented tsunami run-up heights and arrival times with our modeling results neither allows us to confirm nor can we falsify the hypothesis that the earthquake triggered these submarine landslides.
