Yūryaku Seamount facts for kids
Yūryaku Seamount (雄略海山) is a fascinating underwater mountain found in the Pacific Ocean. It's a type of volcano that is completely hidden beneath the waves. Yūryaku is part of a very long line of underwater mountains called the Hawaiian–Emperor seamount chain.

What is a Seamount?
A seamount is basically a mountain that rises from the ocean floor but does not reach the surface of the water. Most seamounts are old volcanoes. They are often shaped like cones, just like volcanoes on land.
Yūryaku: A Flat-Topped Mountain
Yūryaku Seamount is special because it has a flat top. Because of this flat top, it's also known as a "guyot" or "tablemount." Imagine a mountain with its very top chopped off – that's what a guyot looks like!
How Guyots Get Flat Tops
Guyots become flat-topped over millions of years. When these volcanoes were active, their tops might have been above the ocean surface. Waves and weather slowly eroded the top, making it flat. Then, as the ocean floor moved, the seamount slowly sank deeper into the water.
An Ancient, Extinct Volcano
Yūryaku Seamount is an extinct volcano. This means it will never erupt again. Its last eruption happened about 43 million years ago! That's a very, very long time ago, even before dinosaurs disappeared.
Named After an Emperor
This amazing undersea mountain is named after Emperor Yūryaku of Japan. Many features in the Hawaiian–Emperor seamount chain are named after important figures or places.
Exploring the Deep Ocean
Scientists use special tools and submarines to explore seamounts like Yūryaku. These underwater mountains are important for ocean life. Many different kinds of fish, corals, and other sea creatures live around them. They provide places for animals to hide, feed, and raise their young.
