As much as they may inspire fear in us, volcanoes also fascinate us. Here is an overview of the world's most famous volcanoes, as well as some fascinating facts about this natural phenomenon. 

Volcano Trivia

What Causes Volcanoes to Erupt?

A volcano erupts when thick magma is forced to its surface, causing a build up of pressure that is released through an explosion. 

Why Do Volcanoes Erupt?

Are Volcanoes Mountains?

A similarity exists between mountains and volcanoes. However, there is a difference in their formation. A mountain results from various geological processes such as movement and opposition of tectonic plates. On the other hand, a volcano forms around a vent when magma flows out and reaches the surface of the earth.

When Is A Volcano Considered Active, Dormant, Or Extinct?

Volcanoes are classified as active, dormant, or extinct based on their activity since the last Ice Age. Active volcanoes are those that have seen some volcanic activity within the last 10,000 years. Dormant volcanoes are those that have erupted sometime before or after the last Ice Age and retains the ability to erupt again in future, but has not seen any activity in the past 10,000 years. Extinct volcanoes are those that have had no activity in the past 10,000 years and are believed to lack the ability to ever erupt again.

What Are Submarine Volcanoes?

Submarine volcanoes are fissures in the surface of the Earth through which the magma can erupt, and they account for 75% of the output of the material. They are located in the deep ocean and the seas, but some of them can be found in the shallower waters as well. Submarine volcanoes are also found near the tectonic plate movements, which are known as ocean ridges.

What Is Tallest Volcano In The World?

Nevado Ojos del Salado, a stratovolcano in the Andes, is the highest active volcano in the world. It has an elevation of 22,615 feet. The most recent major eruption happened 1,300 years ago. The volcano is situated on the Argentina-Chile border near the Atacama Desert.

Where is Paricutin?

When Did the Soufrière Hills Volcano Erupt?

In 1995, the Soufrière Hills volcano on the Caribbean island of Montserrat became active. As a result, half of Montserrat became uninhabitable. As the volcano had been dormant for over 3 centuries and had been deemed inactive, this came as a devastating blow to the small island and its inhabitants.

Where Are Most Volcanoes Likely To Form?

Volcanoes are common in along tectonic plate boundaries. For instance, 75% of the worlds' active and dormant volcanoes are around Pacific Ring of Fire.
