Figure 1

Bathymetric map of Norwegian Sea and North Sea regions showing area of the Storegga submarine landslides (after Bugge, 1983 and Bugge et al., 1987). Dots show the principal locations where coastal deposits exist that have been attributed to deposition by the tsunami generated by the Second Storegga Slide. The graphs for sites 1, 2 and 3 are numerical model predictions of tsunami height offshore according to Harbitz (1992) (cf. also Figure 16). Note the pronounced initial drawdown and the extreme and astonishingly rapid water-level fluctuations at the Norwegian offshore site
