摘要东北法罗边缘的高分辨率地震剖面显示，中、下陆坡发生了大规模的滑塌和滑动，影响了推测的中新世、上新世和第四纪沉积物。上斜坡上的物质流沉积物部分被较新的沉积物覆盖，推测为等深流岩。一个TOBI深拖侧扫声纳镶嵌图，结合深拖穿透回声测深仪的结果，表明上斜坡上的滑塌复合体包括一个埋藏的滑动疤痕，瓶颈幻灯片，泥石流瓣和一些浅幻灯片。在大陆坡中部和下部的滑动似乎是最近才发生的，显示出一个陡峭、不规则的主滑塌痕和非常大、完整的角块。下大陆坡的滑坡底部有许多狭窄而分散的轨迹，长度为10至15公里，止于个别块体。几种类型的泥石流已被绘制成图，有些具有纵向流动结构。
Abstract High-resolution seismic profiles of the NE Faeroe margin show large-scale slumping and sliding of the middle and lower continental slope, affecting sediments of presumed Miocene, Pliocene and Quaternary age. Mass-flow deposits on the upper slope are partially covered by more recent deposits, presumed to be contourites. A TOBI deep-tow side-scan sonar mosaic, in combination with deep-towed penetrating echosounder results, shows that the slump complex on the upper slope consists of a buried slide scar, bottleneck slides, debris-flow lobes and a number of shallow slides. Sliding at the middle and lower continental slope seems more recent and shows a steep, irregular main slump scar and very large, intact, angular blocks. The base of the slide at the lower continental slope shows numerous narrow and diverging tracks, 10–15 km length, that end at individual blocks. Several types of debris flows have been mapped, some with longitudinal flow fabrics.
