Location: A nearly continuous chain of volcanoes surrounds the Pacific Ocean.They include Mariana trench, Guam trench etc. Trenches The edges of plates are destructive boundaries and as a result large trenches are found.Edges of continental plates The Circum-Pacific zone consists of edges of continental plates such as Asian plate, Pacific plate, Nazca plate, Cocoa plate etc.They are thus prone to regular earthquakes. Convergent zone The Circum-Pacific zone is a convergent zone between continental and oceanic plate.This includes Mt Fiji, Mt Pinatubo, Mt Chimborazo, Mt Krakatau etc. Ring of fire Majority of global volcanoes are present along the perimeter of Circum-Pacific zone.Archipelago clusters The Circum-Pacific zone consists of clusters of archipelago such as Japan, Philippines, Indonesia, Polynesia, Chile etc.Geophysical characteristics of Circum-Pacific Zone It is the most seismically active region followed by Alpide Belt that extends from Java to the northern Atlantic Ocean via the Himalayas & Southern Europe More than 80 percent of the world’s largest earthquakes occur along the circum-pacific belt. It is home to around 452 volcanoes (active and dormant volcanoes both) 3. The ring of fire features the following: Oceanic trenches Volcanic arcs, and Volcanic belts and/or plate movements 2. What are the features of the ring of fire?ġ. What are the countries/Cities located in the ring of fire?īolivia, Chile, Ecuador, Peru, Costa Rica, Guatemala, Mexico, United States, Canada, Russia, Japan, Philippines, Indonesia, New Zealand, and Antarctica are some of the important places located in the ring of the fire. What is the length of the circum-pacific belt? A horseshoe-like shape is formed with the ring of fire. Also, since more than 75 percent of earth’s volcanoes and 90 percent of earthquakes are witnessed here, it is called the ring of fire. It is so-called because it marks a track around the rim of the pacific ocean. It is also called the Circum-Pacific Belt or Circum-Pacific Seismic Belt. The path located at the rim of the pacific ocean, which is characterized by active volcanoes and earthquakes is called the ring of fire. It stretches from Bering strait in Siberia to New Zealand and coast of Chile to Alaska.Circum-Pacific zone is also a source of study to determine orogenesis process such as continent formation, earthquake activities, volcanic activity etc. This is the area with the most earthquakes and volcanoes in the world.Ĭircum-Pacific zone is the region encompassing the coast of Asia, Australia, and Americas. In the subduction zone where these plates overlap at the convergence boundary, the sliding between the plates and the rupture within the plates can cause earthquakes. This is a typical zone where oceanic crustal plates sink or subduct under another plate. The belt runs along the boundary of the tectonic plate. In addition, it has experienced the most violent and dramatic earthquake events. More than 85% of earthquakes on the earth occur on this path. The Pacific Rim seismic zone is the largest seismic zone in the world, located on the edge of the Pacific Ocean.
It contains most of the subduction zones on the earth. Many of these volcanoes were formed through the process of subduction. Most active volcanoes on earth are underwater. It is composed of more than 450 volcanoes. The Pacific Rim of Fire is the area where the Pacific Plate meets many surrounding tectonic plates and forms a horseshoe shape.
