`color{blue}✎` On the basis of mode of eruption Central Eruption or Explosive Type Here, the magma comes with great force through the small vent and spread to a distant position. e.g. Hawaiian type, Strombolian type, Pelcan type, Visuvius type, Volcanion type.
Fissure Eruption or Quiet Eruption : Large quantities of lava quietly flow up from fissures and spread out over the surrounding areas. Successive flow of lava results in the growth of lava plateau. e.g. Deccan Plateau.
`color{blue} ✍️` On the basis of periodicity of eruptions
Active Volcano : Volcano which errupt periodically. e.g. Etna, Stromboli, Mayon.
Dormant Volcano : Volcano which become quiet after their eruption for some time. e.g. Fujiyama, Krakatoa, Barren Island.
Extinct Volcano : They have no indication of future eruption.
`color{blue}✎` The most common type of volcano is the strato or composite. These are tall mountains that have steep sides and which have alternated magma and layers of rock.
`color{purple} {"Eruption Classification"}`
There are two types of classification of volcanoes based on eruption and these are `color{blue}{"central or explosive"}` and `color{blue}{"fissure or quiet"}`.
`color{green} ✍️` There are several factors that go into account when attempting to classify a volcano into a group and that includes things like recent activity, periodicity of eruptions, size, potential impact and others.
`color{green} ✍️` Though it is not common to hear it volcano eruptions are actually not that rare. More often than not the classification of volcanoes refers to the life cycle and that could define them as `color{blue}{"active, extinct or dormant"}`.
`color{green} ✍️` However, a volcano can also be classified by the composition of the structure and that would mean that it can be a shield, conical or stratovolcano. Finally they can also be classified because of its eruption which could be quiet or explosive.
`color{green} ✍️` Following figure given on the right shows the different types of volcanoes.
`color{purple} {"Various Volcanic Belts"}`
`color{blue} ►`Circum-Pacific Belt (Fire girdle of the pacific or the fire ring of the pacific) : It extends across the Kamchatka Peninsula, Kurile Islands, the Islands of Japan, Philippines, New Guinea, New Zealand and the Soloman Islands.
`color{blue} ►`Highest Volcanic Peaks Cotopaxi (South America), Fujiyama (Japan, Valley of ten thousand smokes (Alaska).
`color{blue} ►`Mid-Continental Belt (Volcanic zones of convergent continental plate margins) : It includes volcanoes of Air inc mountain chain, the Mediterranean sea and the fault zone of Eastern Africa of Stromboli, Vesuvias, Etna, Kilimanjaro etc.
`color{blue} ►`Mid-Atlantic Belt in which the volcanoes are fissure eruption type, e.g. Iceland, Canary Islands, Cape Verde, Azores etc.
