According to the United States Geologic Survey, there are approximately 1, potentially active volcanoes worldwide. Most are located around the Pacific Ocean in what is commonly called the Ring of Fire. A volcano is defined as an opening in the Earth's crust through which lava, ash, and gases erupt.

How are the plate tectonics related to the ring of fire?
This is when plates slide against each other in a horizontal slip motion. The San Andreas Fault is an example of this. Volcanoes do not form on transform faults but earthquakes do occur. Watch: The Pacific Ring of Fire explained. Geoscience Australia Senior Seismologist Professor Phil Cummins said the term volcano refers to the process of formation and whether it was formed as a result of volcanic eruption.
The words active, dormant and extinct are often used to describe volcanoes, but definitions for their use are bit vague. An active volcano is one that erupts regularly, as would be the case for any volcano that has erupted historically. A dormant volcano is an active volcano that has not erupted recently but may erupt in the future, such as one for which there is no historical knowledge of an eruption but there is geologic evidence pointing to an eruption in the past 10, years.
An extinct volcano is one that is expected to never erupt again, such as a volcano that has not erupted in the past 10, years. Professor Cummins said the distinction between a major and minor plate is determined by its size.
For more than six years since a deadly earthquake struck Christchurch in February , the city's iconic cathedral sat in ruins in the city center. New Zealand is one of the countries that sits within the Pacific Ring of Fire. A lahar is a volcanic mudflow, a mix of rock and water, which can occur with or without eruption. They occur typically when a landscape has been covered by loose volcanic material and they pick up material as they travel, causing destruction to whatever is in its path.
An Indonesian man looks at the huge river forged by the flow of lahar from Mount Merapi, in Java in The Aleutians are the most northern part of the pacific Ring of Fire.
They are an island chain in Alaska that consists of more than small volcanic islands. These form an arc in the northern Pacific Ocean which stretches from the Alaskan Peninsula to far eastern Russia. Photo shows the eruption of Wolf volcano, at Isabela island, Galapagos, on 25 May , home to the only population of pink iguanas in the world. It stretches from the coast of Central America to South America and is home to submarine volcanoes, islands, trenches, and hydrothermal vents. One of the most famous locations is the Black Smokers near the Galapagos Islands off the South American west coast, considered the first hydrothermal vents discovered on Earth.

This is the most famous transform boundary see above in the world, the San Andreas Fault is found along the south west coast of California in the United States. It slices the area in two from Cape Mendocino to the Mexican border. Where fire meets ice at the most active volcano in Antarctica.
