Info from Licensor: " When walking along the Sermilik Fjord we were suddenly astonished by the spectacle of a football field-sized iceberg which collapsed out of the blue. The rupture was one thing, but the overturn was massive. This provoked a tsunami tidal wave of 5m high which rammed into the coast where we would normally walk. Luckily at that time, we were ascending a rocky slope to avoid a rock band along the coast and we were at some 50m above sea level."
