Abstract

A submarine sediment instability event (landslide) occurred at Kitimat, British Columbia, in 1975. Recent high-resolution surveys provide details of the resulting seafloor morphology. The effects of the slide include modification of the fjord head delta-front slopes, transport of delta sediments into deep water and mixing with deep water, fjord bottom clays. Distinctive features include the results of shallow rotational sliding, tearing and shearing, compressional folding and long distance block gliding at the downslope slide terminus.
