Prehistoric Submarine Landslides

• The Storegga Slide, Norway, ca. 3,500 km3 (840 cu mi), ca. 8,000 years ago, a catastrophic impact on the contemporary coastal Mesolithic population
• The Agulhas slide, ca. 20,000 km3 (4,800 cu mi), off South Africa, post-Pliocene in age, the largest so far described
• The Ruatoria Debris Avalanche, off North Island New Zealand, ca. 3,000 km³ in volume, 170,000 years ago.
• Catastrophic debris avalanches have been common on the submerged flanks of ocean island volcanos such as the Hawaiian Islands and the Cape Verde Islands.
