5 MASSIVE VORTICES

1 SALTSTRAUMEN

In Norway, south of the city of Bodø, a small strait has one of the strongest tidal currents in the world. Where Skjerstad Fjord and Salten Fjord link together, water can travel at ten metres per second to create this giant whirlpool up to ten metres wide and five metres deep.

2 OLD SOW

Formed in the waters between Deer Island and Moose Island in Canada, Old Sow is one of the largest whirlpools in the Western Hemisphere. It can vary in size, within a diameter of 76 metres. Usually several smaller whirlpools surround it.

3 NARUTO

Between Tokushima and Hyōgo in Japan, this tidal whirlpool can form up to 20 metres in diameter. Water enters the narrow Naruto strait at speeds of 12 miles per hour during spring tides.

4 CORRYVRECKAN

Located between two rocks off the west coast of Scotland, this whirlpool is produced by the uneven seabed. Deep pits and basalt pinnacles increase the speed of the water that flows through. It’s considered to be the third-largest whirlpool in the world.

5 MOSKSTRAUMEN

In the Norwegian Sea between the island of Mosken and the southern part of the island of Moskenesøya is the second-strongest whirlpool in the world. At its largest it’s about 49 metres in diameter.
