The 1600-km-long North Anatolian transform fault across northern Turkey has been repturing from east to west in a series of large earthquakes during the past 60 years. The rupture front advanced 160 km westward in 1999 in two disastrous earthquakes. The next rupture is expected to occur within the next few decades benearth the Marmara Sea. In October 2000, the shelf and adjacent slope of the northeastern Marmara Sea were charted using multibeam bathymetry and backscatter technology. The goal was to resolve the planview geometry of seismogenic fault strands, and to identify any related features such as mass-wasting deposits, sand blows, mud volcanoes, and degassing craters.

在过去60年中，整个土耳其北部的1600公里长的北部安纳托利亚转型断层在一系列大地震中一直从东到西。 1999年在两次灾难性的地震中，破裂的阵线向西160公里。 预计下一次破裂将在接下来的几十年中发生在马尔马拉海贝纳尔斯。 2000年10月，使用Multibeam测深和反向散射技术绘制了Marmara Sea东北部的架子和邻近坡度。 目的是解决地震发生断层链的平面文化几何形状，并确定任何相关特征，例如大量浪费沉积物，沙吹，泥土火山和脱气的陨石坑。
