Philippines

FilipinoPhilippinePhilippine Islands
The western portion is more complex, with a number of smaller tectonic plates in collision with the Pacific Plate from the Mariana Islands, the Philippines, Bougainville, Tonga, and New Zealand.
The Philippines' location on the Pacific Ring of Fire and close to the equator makes the Philippines prone to earthquakes and typhoons, but also endows it with abundant natural resources and some of the world's greatest biodiversity.

Plate tectonics

tectonic platesplate tectonictectonic
The Ring of Fire is a direct result of plate tectonics: the movement and collisions of lithospheric plates, especially subduction in the northern portion.
The majority of the world's active volcanoes occur along plate boundaries, with the Pacific Plate's Ring of Fire being the most active and widely known today.

Aleutian Islands

AleutiansAleutianAleutian Chain
Along the northern portion, the northwestward-moving Pacific Plate is being subducted beneath the Aleutian Islands arc. Farther west, the Pacific Plate is being subducted along the Kamchatka Peninsula arcs to the south past Japan.
The islands, with their 57 volcanoes, form the northernmost part of the Pacific Ring of Fire.

Alpide belt

Alps-Himalaya SystemAlpideAlp-Himalayan
The next most seismically active region (5–6% of earthquakes and 17% of the world's largest earthquakes) is Alpide belt, which extends from Java to the northern Atlantic Ocean via the Himalayas and southern Europe.
It is the second most seismically active region in the world, after the circum-Pacific belt (the Ring of Fire), with 17% of the world's largest earthquakes.

California

CAState of CaliforniaCalifornia, USA
The famous and very active San Andreas Fault zone of California is a transform fault, which offsets a portion of the East Pacific Rise under the southwestern United States and Mexico; the motion of the fault generates numerous small earthquakes, at multiple times a day, most of which are too small to be felt.
As part of the Ring of Fire, California is subject to tsunamis, floods, droughts, Santa Ana winds, wildfires, landslides on steep terrain, and has several volcanoes.

Japan

JPNJapaneseJP
Along the northern portion, the northwestward-moving Pacific Plate is being subducted beneath the Aleutian Islands arc. Farther west, the Pacific Plate is being subducted along the Kamchatka Peninsula arcs to the south past Japan. Farther south, the eastern belt continues to the southern slope of Kamchatka, topped by loads of stratovolcanoes, continuing onto the Kuril Islands with about 40 active volcanoes, and south into Japan.
The islands of Japan are located in a volcanic zone on the Pacific Ring of Fire.

Indonesia

Republic of IndonesiaIndonesianIndonesian Republic
Indonesia lies between the Ring of Fire along the northeastern islands adjacent to and including New Guinea and the Alpide belt along the south and west from Sumatra, Java, Bali, Flores, and Timor.
It lies on the Pacific Ring of Fire where the Indo-Australian Plate and the Pacific Plate are pushed under the Eurasian plate where they melt at about 100 km deep.

Earthquake

The Ring of Fire (also known as the Rim of Fire or the Circum-Pacific belt) is a major area in the basin of the Pacific Ocean where many earthquakes and volcanic eruptions occur.
Most of the world's earthquakes (90%, and 81% of the largest) take place in the 40000 km, horseshoe-shaped zone called the circum-Pacific seismic belt, known as the Pacific Ring of Fire, which for the most part bounds the Pacific Plate.

Chile

Republic of ChileChileanCHI
Many of the active volcanoes are international mountains shared with Chile.
It is situated within the Pacific Ring of Fire.

Santiago

Santiago, ChileSantiago de ChileGreater Santiago
It is situated 82 km northeast of Temuco and 663 km southeast of Santiago, within the borders of Conguillío National Park.
Due to Santiago's location on the Pacific Ring of Fire at the boundary of the Nazca and South American plates, it experiences a significant amount of tectonic activity.

Cotopaxi

Cotopaxi VolcanoCotapaxi Cotopaxi volcano
Cotopaxi is a stratovolcano in the Andes, located about 50 km south of Quito, Ecuador, South America.
On a clear day, Cotopaxi is clearly visible on the skyline from Quito and is part of the chain of volcanoes around the Pacific plate known as the Pacific Ring of Fire.

Juan de Fuca Plate

Juan de FucaJuan de Fuca tectonic plateJuan de Fuca oceanic plate
A portion of the Pacific Plate and the small Juan de Fuca Plate are being subducted beneath the North American Plate. The arc is formed by the subduction of the Gorda and Juan de Fuca Plates at the Cascadia subduction zone.
These in turn are part of the Pacific Ring of Fire, a much larger-scale volcanic feature that extends around much of the rim of the Pacific Ocean.

Pacific Ocean

PacificSouth PacificWestern Pacific
The Ring of Fire (also known as the Rim of Fire or the Circum-Pacific belt) is a major area in the basin of the Pacific Ocean where many earthquakes and volcanic eruptions occur.
Outside the andesite line, volcanism is of the explosive type, and the Pacific Ring of Fire is the world's foremost belt of explosive volcanism.

Mount St. Helens

Mount Saint HelensMt. St. HelensMount St Helens
The eruption was preceded by a two-month series of earthquakes and steam-venting episodes caused by an injection of magma at shallow depth below the mountain that created a huge bulge and a fracture system on Mount St. Helens' north slope.
The volcano is located in the Cascade Range and is part of the Cascade Volcanic Arc, a segment of the Pacific Ring of Fire that includes over 160 active volcanoes.

Castle Rock (volcano)

Castle Rock
Hot springs are at some volcanoes, while 10 volcanoes in British Columbia appear related to seismic activity since 1975, including: the Silverthrone Caldera, Mount Meager massif, Wells Gray-Clearwater volcanic field, Mount Garibaldi, Mount Cayley massif, Castle Rock, The Volcano, Mount Edziza, Hoodoo Mountain, Crow Lagoon, and Nazko Cone.
Castle Rock is part of the Pacific Ring of Fire that includes over 160 active volcanoes and is in the Klastline Group, Northern Cordilleran Volcanic Province and last erupted in the Pleistocene.

Northern Cordilleran Volcanic Province

Stikine Volcanic Belt
The Northern Cordilleran Volcanic Province (sometimes known as the Stikine Volcanic Belt) is the most active volcanic region in Canada.
The Northern Cordilleran Volcanic Province is part of an area of intensive earthquake and volcanic activity around the Pacific Ocean called the Pacific Ring of Fire.

Pacific Plate

PacificPacific tectonic platePacific crust
The western portion is more complex, with a number of smaller tectonic plates in collision with the Pacific Plate from the Mariana Islands, the Philippines, Bougainville, Tonga, and New Zealand. A portion of the Pacific Plate and the small Juan de Fuca Plate are being subducted beneath the North American Plate.
A geologic map of the Pacific Ocean seabed shows not only the geologic sequences, and associated Ring of Fire zones on the ocean's perimeters, but the various ages of the seafloor in a stairstep fashion, youngest to oldest, the oldest being consumed into the Asian oceanic trenches.

Tseax Cone

The nearby Tseax Cone and The Volcano produced some of Canada's youngest lava flows, about 150 years old.
The Tseax Cone is in the southern part of the Northern Cordilleran Volcanic Province and is therefore part of the Ring of Fire.

Volcano

It has 452 volcanoes (more than 75% of the world's active and dormant volcanoes).
For example, a mid-oceanic ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates.

Volcanic belt
