The Storegga Slides: Evidence from eastern Scotland for a possible tsunami

Abstract The Second Storegga Slide on the continental slope off western Norway has been dated at between 8000 and 5000 yrs B.P. A prominent sand layer in Flandrian (Holocene) deposits along the coast of eastern Scotland, and dated at approximately 7000 yrs B.P. may have been deposited by a tsunami generated by the slide. The altitude and stratigraphy of the layer allow estimates to be made of the magnitude of the earthquake which initiated the slide.
