Tulivuorivyö

Tulivuorivyö, also known as a ring of fire, is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur. The term was first used by American geologist Woodrow Wilson in 1898. The ring of fire is about 40,000 kilometers (25,000 miles) long and includes 452 volcanoes and over 540 active and dormant volcanoes. It is home to 75% of the world's active volcanoes and 90% of the world's earthquakes.

The ring of fire is caused by the subduction zones where one plate of the Earth's lithosphere is forced underneath another, leading to volcanic activity and earthquakes. The area is characterized by frequent seismic and volcanic activity, making it a significant area of study for geologists and seismologists.

The ring of fire stretches from the southern tip of South America, across the coast of North and South America, up along the coast of Asia, and into the western Pacific. It includes the Andes mountains in South America, the Cascade Range in the western United States, the Japanese archipelago, and the Philippines.

The ring of fire is also known for its diverse ecosystems and cultural significance. Many indigenous communities live in the region, and the area is rich in natural resources. However, the frequent natural disasters also pose significant challenges to human settlements and infrastructure.
