Where are Most Volcanoes Likely to Form?
- Convergent Plate Boundaries. Convergent boundaries, also called subduction zones, are areas where an oceanic or continental tectonic plate goes under another plate.
- Divergent Tectonic Plate Boundaries. Divergent boundaries, also called extensional boundaries, are areas where plates are moving away from each other.
- Volcanic Hot-Spots. Volcanic hot spot makes an area likely to form volcanoes. ...
- Formation of Volcanoes. The dynamic nature of earth's interior is responsible for the formation, hence the distribution of volcanoes.

What is the most dangerous volcano in the world?
- Krakatoa volcano destroyed over 70% of its land back in 1883, after four major explosions triggered the disaster.
- Mount Fuji had not erupted for over 300 years. ...
- The last eruption of Mount Vesuvius happened in 79 AD and it completely mummified the entire city of Pompeii by covering it with lava.
What is the most dangerous type of volcano?
This lava plugs up the plumbing in stratovolcanoes, allowing them to build up tremendous amounts of pressure. Of all the volcanoes on Earth, stratovolcanoes are the most dangerous. They can erupt with little warning, releasing enormous amounts of material. And they don't always erupt nicely from their tops.

What is the third place a volcano can form?
A hotspot is the third place a volcano can form. This particular type is the least common. Hot spots are when thermal plumes from deep in the Earth rises. This heat, combined with the lower pressure at the bottom of the lithosphere, causes magma to form.
How are earthquakes generated?
An earthquake is generated when two plates move relative to each other. The earthquake itself, is the movement felt on the surface caused by the movement of the tectonic plates at their boundaries.
Convergent Plate Boundaries
Divergent Tectonic Plate Boundaries
- Divergent boundaries, also called extensional boundaries, are areas where plates are moving away from each other. The movement creates gaps and magma can easily reach the surface leading to volcanic activity. The movement is also the reason behind volcanoes in East African Rift valley, southwestern US's Basin, and Range (New Mexico and Nevada) Province, and mid-oc…
Volcanic Hot-Spots
- Volcanic hot spot makes an area likely to form volcanoes. For unclear reasons, some areas of the mantle referred to as plumes, become far hotter than the rest of the mantle. The plume rises upwards towards the surface, and where it finds a weakness in the crust, it flows through leading to an outpouring of lava hence forming volcanoes. There is no ...
Formation of Volcanoes
- The dynamic nature of earth's interior is responsible for the formation, hence the distribution of volcanoes. Most of the volcanoes are caused by tectonic plates pushing against each other in areas where two or more plates meet. Fewer volcanoes are formed where plates are moving away from each other leading to the crust becoming thinner than usual. The rarest type of volcanoes …
