The Pacific Ring of Fire is a 25,000-mile (40,000 km) horseshoe-shaped area of intense volcanic and seismic (earthquake) activity that follows the edges of the Pacific Ocean. The Ring of fire, which takes its name from the 452 dormant and active volcanoes located within it, contains 75% of the world’s active volcanoes and is also responsible for 90% of the world’s earthquakes.
Where’s the Pacific Ring of Fire?
The ring of fire is a mountain, volcano, and oceanic trench that extends from New Zealand north along the eastern edge of Asia, then east along the Aleutian Islands of Alaska, and then south along the western coasts of North and South America.
What created the Pacific circle of Fire?
The circle of fire was formed by plate tectonics. Tectonic plates are like giant rafts sliding side by side on the Earth’s surface and colliding. The Pacific Plate is quite large and is therefore bounded (and interacts with) several large and small plates.
The interactions between the Pacific Plate and the surrounding tectonic plates create enormous amounts of energy, which allows the rocks to melt easily with magma. This magma then rises to the surface as lava and forms volcanoes.
Major volcanoes in the Pacific Ring Of Fire
With 452 volcanoes, The Ring of Fire is home to quite ‘famous’ volcanoes. The list of major volcanoes in the circle of fire is as follows:.
Andes-stretching in a north-south direction of 5,500 miles (8,900 km) along the western edge of South America, the Andes Mountains are the longest continental mountains in the world. The Andean Volcanic Belt is in a mountainous region and is divided into four volcanic zones, which include active volcanoes such as Cotopaxi and Cerro Azul. It is also home to the highest active volcano, Ojos del Salado.
Popocatepetl-Popocatepetl is an active volcano in the Trans-Mexican Volcanic Belt. This volcano, located near Mexico City, is considered by many to be the most dangerous volcano on earth, as a massive eruption could potentially kill millions of people.
Mount St Helens-the Cascade Mountains in the Northwestern Pacific region of the United States are home to the 1,300 km Cascade Volcanic Arc. The Cascades contain 13 large volcanoes and about 3,000 volcanic structures. The most recent eruption in the Cascades occurred on Mount Saint Helens in 1980.
Aleutian Islands-Alaska’s Aleutian Islands, consisting of 14 large and 55 small islands, were formed by volcanic activity. The Aleutian contains 52 volcanoes, the most active of which are Cleveland, Okmok, and Akutan.
Mount Fuji-located on the Japanese island of Honshu, Fuji, at 3,776 m (12,380 feet), is the highest mountain in Japan and the most visited in the world. However, Fuji is more than a mountain, it is an active volcano that last erupted in 1707.
Krakatoa-located on the Indonesian island arc, Krakatoa. Everyone remembers his Big Bang (considered the loudest sound in modern history) on August 27, 1883, which killed 36,000 people and was heard 2,800 miles away. The Indonesian island arc is also home to Mount Tambora, the largest eruption in known history, with its eruption on April 10, 1815, calculated as 7 in the volcanic eruption Index (vei).
Mount Ruapehu-with an elevation of 2797 m (9,177 feet), Ruapehu is the highest mountain in the North Island of New Zealand. Located in the southern part of the Taupo Volcanic Zone, Ruapehu is New Zealand’s most active volcano.
The Pacific Ring of Fire, a place that produces most of the world’s volcanic activity and earthquakes, is a fascinating place. Understanding more about the Ring of fire and being able to accurately predict volcanic eruptions and earthquakes could perhaps help save millions of lives.
