The Pacific Ring of Fire is the terminology given to a u-shaped area that is almost forming a ring or a circle in the Pacific Ocean expanding all the way from South America and North America to Eastern Asia, New Zealand and Australia. The stretch is approximately 40,000 kilometers (25,000 miles) from New Zealand, all the way to the West Pacific through the Philippines, Japan and Indonesia, covering parts of Bering Strait between Alaska and Russia, and extending all the way to the West coasts of North America and South America. This ring accounts for 452 volcanoes (active and dormant).
The area is widely known because of its continued seismic activity influenced by the numerous numbers of active volcanoes around the region. About 75% of all active and dormant volcanoes are found in the Pacific Ring of Fire. Geologists conjure that the violent volcanic activities in the area is because the region is very close to numerous tectonic plates that are frequently subjected to subduction. For this reason, the Pacific Ring of Fire has persisted to be an active location for volcanoes and earthquakes.
More than three-quarters of the world’s volcanoes have been produced from the Pacific Ring of Fire. So, the main point is that the Pacific Ring of Fire is an extensive chain of volcanoes and other tectonically active processes such as earthquake and ocean trenches fault zones closely encircling the Pacific Ocean. About 90% of the strongest volcanic eruptions and approximately 81% of the world’s most damaging earthquakes have taken place along the Pacific Ring of Fire.
Wikipedia defines it as,
“The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements.“
Major Causes of Pacific Ring of Fire
- Tectonic Activities
The Ring of Fire is a direct outcome of the tectonic activities in the Pacific Ocean. The lithosphere plates are in constant motion and collisions. These plates making up the outermost layer of the earth are always moving on top of the mantle and sometimes pull apart, collide, or slide past each other resulting in divergent boundaries, convergent boundaries, and transform boundaries respectively.
Subduction zones are also predominant due to the action of the tectonic movements when heavier plates slip under lighter plates, creating deep trenches. The subduction alters the heavy mantle into buoyant magma which moves up the crust to the surface of the earth. When this occurs over millions of years, the rising magma brings about a series of active volcanoes referred to as volcanic arc.
The volcanic arcs and ocean trenches run parallel to each other thereby bringing about the ever expanding Pacific Ring of Fire. For example, the Aleutian Islands in Alaska run parallel to the Aleutian Trench. What’s more, the Andes Moutains of South America runs parallel to the Peru-Chile Trench. These parallel geologic features are the ones responsible for the subductions of the Plates.
When it comes to plate tectonic boundaries, it leads to faulting, crashing, and formation of rift valleys on the sea floor which contributes to the ejection of magma and powerful shaking of the ocean floor. This leads to the formation of more cracks, vents, and fault lines which can trigger strong earthquakes and volcanic activities. The ejected magma is cooled by the seawater to form new crust, creating high ridges on the ocean floor. The East Pacific Rise is one of the major locations experiencing fast seafloor spreading in the ring of fire.
- Plate Boundaries
The Pacific is a region with numerous plate tectonic boundaries. As a result, there is a constant activity of the plates pulling apart, colliding, or sliding past each other resulting in divergent boundaries, convergent boundaries, and transform boundaries respectively. The eastern section of the Ring of Fire for instance is as a result of the Cocos Plate and Nazca Plate being subducted under the wesward moving South American Plate.
At the same time, the Cocos Plate is under subduction by the forces of the Caribbean Plate in Central America. Besides, beneath the North American plate there is the subduction of a small portion of the Juan de Fuca Plate along with a section of the Pacific plate. On the northern side, the northwestward-moving Pacific Plate is under subduction below the Aleutian Islands arc. Further to the west, the Pacific Plate is under subduction along the Kamchatka Peninsula arcs in the south.
Furthermore, the southern section is even more intricate and exhibits the collisions of several tectonic plates. This includes collisions with the Pacific Plate from the Philippines, Mariana Islands, New Zealand and Tonga. The Australian, California, and Indonesian plates also show similar signs on the active plate boundaries activities.
- Volcanic Activity
It is undeniable that most of the world’s active volcanoes and volcanic activities are within the Pacific Ring of Fire. Therefore, they account for one of the major causes of the active geological activities in the Pacific. Most of the regions on the Ring of Fire show an attribute of active volcanic activities. It stretches right from the western edge, from the Kamchatka Peninsula in Russia through the Japan Islands and Southeast Asia, to New Zealand.
For instance, Mount Ruapehu in New Zealand is among the most active volcanoes within the Ring of Fire and records minor eruptions every year and major eruptions in almost every five decades. On the Indonesian pacific, the Krakotoa eruption is quite frequent. The same applies to the Australian pacific.
Major Volcanic Areas in the Pacific Ring of Fire
According to the Universe Today, there are more than 450 dormant and active volcanoes present within the Pacific Ring of Fire. Some of the globe’s most active volcanoes are found in this location. The active volcanoes areas stretch right from the western edge, from the Kamchatka Peninsula in Russia through the Japan Islands and Southeast Asia, to New Zealand. Kilauea is believed to be the most active volcano in the world found in the Pacific Ring of Fire.
- Mount Ruapehu
Mount Ruapehu is in New Zealand section of the pacific, on the southern end of the Taupo Volcanic Zone. It is among the most active volcanoes within the Ring of Fire and records minor eruptions every year and major eruptions in almost every five decades. According to history, it started erupting 250,000 years ago. Over the years it has produced several explosives scoria cones, craters, and lava flows. In December 1993, 151 people lost their lives as a result of Mount Ruapehu volcanic activity.
- Krakatau in Indonesia
Krakatau, also referred to as Krakatoa, is an Indonesian island that exhibits active volcanic activities. However, it erupts less often compared to mount Ruapehu. Below Krakatau, there is an extensive plate tectonic activity the influences the volcanism. The denser Australian Plate below Krakatau is under subduction beneath the Eurasian Plate.
A very destructive eruption took place in 1883, destroying the entire island and emitting large scores of volcanic ash, gas, and rocks high into the air at a height of more than 80 kilometers (50 miles). Since, minor eruptions still take place at the new island volcano.
- Mount Fuji
Mount Fuji is in Japan and is the most famous and tallest mountain in the region. It is still an active volcano in the Pacific Ring of Fire. It erupted last in 1709 and it has been recently reported to be active due to the tectonically active processes, mainly earthquakes. Mount Fuji is as well located at a ‘triple junction,’ where three tectonic plates interact. These include the Philippine, the Amur, and Okhotsk Plates.
- The Eastern Half of the Pacific Ring of Fire
The eastern half of the Pacific Ring of Fire has several active volcanic areas including the Trans-Mexican Volcanic Belt, the Andes Mountains, the Aleutian Islands, and the Cascade Mountains in the Western United State which also includes Mount St. Helens.

FAQs
What is the Pacific Ring of Fire and What are Major Causes of it | Earth Eclipse? ›
The Ring of Fire is a direct result of plate tectonics: specifically the movement, collision and destruction of lithospheric plates (e.g. the Pacific Plate) under and around the Pacific Ocean. The collisions have created a nearly continuous series of subduction zones, where volcanoes are created and earthquakes occur.
What is the Pacific Ring of Fire What causes it? ›The abundance of volcanoes and earthquakes along the Ring of Fire is caused by the amount of movement of tectonic plates in the area. Along much of the Ring of Fire, plates overlap at convergent boundaries called subduction zones. That is, the plate that is underneath is pushed down, or subducted, by the plate above.
