Shatsky Rise facts for kids
The Shatsky Rise is a huge underwater mountain range, like a giant plateau, found deep in the Pacific Ocean. It's located southeast of Japan.

What is the Shatsky Rise?
The Shatsky Rise is a very large area of the ocean floor that rises up, forming a kind of underwater plateau. Think of it like a flat-topped mountain that's completely covered by water. It's one of the biggest features of its kind in the world's oceans.
Where is it located?
This massive underwater plateau sits on the bottom of the Pacific Ocean. You can find it to the southeast of the country of Japan. It's a hidden giant beneath the waves.
Home to a Giant Volcano
One of the most exciting things about the Shatsky Rise is that it might be home to the largest volcano ever found on Earth! This super-sized volcano is called the Tamu Massif. It's so big that it covers an area similar to the size of New Mexico in the USA.
How did it form?
Scientists believe the Shatsky Rise and its volcanoes were created a very, very long time ago. This happened during a period known as the Upper Jurassic to Lower Cretaceous epochs. That's about 145 to 160 million years ago! It formed when hot rock from deep inside the Earth pushed up through the ocean floor.
What are Tectonic Plates?
To understand how the Shatsky Rise formed, you need to know about tectonic plates. The Earth's outer layer is broken into huge pieces, like a giant jigsaw puzzle. These pieces are called tectonic plates, and they are always slowly moving. When they move, they can crash into each other, pull apart, or slide past each other, causing things like earthquakes and volcanoes.
A Triple Junction
The Shatsky Rise is special because it sits right at a "triple junction". This means it's where three different tectonic plates meet! These plates are the Pacific, the Farallon, and the Izanagi plates. The way these plates interacted helped create the huge underwater structures we see today.
Who was Nikolay Shatsky?
The Shatsky Rise was named after a famous Soviet geologist named Nikolay Shatsky (1895-1960). He was an expert in studying how ancient landmasses, called "platforms", were formed by the movement of the Earth's crust. Naming this huge underwater feature after him was a way to honor his important work in tectonics.
