In this article, we will introduce "Naruto Straits Uzushio" in a simple and easy-to-understand manner!
What is "Naruto Straits Uzushio"?
Uzushio occurs in the Naruto Straits between Naruto City, Tokushima Prefecture and Hyogo Prefecture!
During high tide, the diameter of the whirlpool is said to reach up to 30 meters, and it is said to be one of the largest whirlpools in the world!
The Council for the Promotion of the World Heritage Registration of "Naruto Whirlpools" in Hyogo and Tokushima defines the size of the whirlpool as "the distance between the outer edges of the whirlpool where the sea surface is at its highest.
How does the "Naruto Straits Uzushio" occur?
There are many factors that cause vortexes, one of which is the ebb and flow of the ocean tides. This is because the gravitational pull of the moon and sun changes the height of the water.
The difference in speed between the high and low tides, which are next to each other across the Naruto Straits, creates a rotating force due to the difference in speed between the fast current flowing in the center and the slow current on the landward side. A whirling whirlpool is then formed!
in the end
Did you know that "there is actually a deep relationship between the whirlpools of Naruto Strait and the moon"?
In the "Uzunetarium" at the Uzushio Science Museum, a spherical screen on the ceiling shows the positional relationship between the earth and the moon, allowing visitors to experience the mechanism of the Uzushio in the entire space! The relationship is explained in detail in the video, so please check it out when you visit the museum!
