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.

横跨土耳其北方的1600公里长的北安纳托利亚转换断层在过去的60年里发生了一系列大地震。 在1999年的两次灾难性地震中，破裂前缘向西推进了160公里。 下一次破裂预计将在未来几十年内发生在马尔马拉海的地下。 2000年10月，利用多波束测深和反向散射技术绘制了马尔马拉海东北部大陆架和邻近陆坡图。 其目标是解析发震断层带的平面几何形状，并识别任何相关特征，如质量浪费沉积物、砂吹、泥火山和脱气火山口。
