Which type of volcanic eruption is the most violent?
Plinian eruptions
The largest and most violent of all the types of volcanic eruptions are Plinian eruptions. They are caused by the fragmentation of gassy magma, and are usually associated with very viscous magmas (dacite and rhyolite).
Which type of volcano produces violent eruptions?
Stratovolcanoes
Stratovolcanoes are more likely to produce explosive eruptions due to gas building up in the viscous magma. Andesite (named after the Andes Mountains), is perhaps the most common rock type of stratovolcanoes, but stratovolcanoes also erupt a wide range of different rocks in different tectonic settings.
Where are the most violent volcanoes formed?
Part of Hall of Planet Earth. Most explosive eruptions occur in volcanoes above subduction zones, where one tectonic plate dives beneath the other. Eighty to 120 kilometers below the surface, magma forms when the rocks of the mantle melt just above the subducting plate.
What causes the most violent eruption of a volcano?
In volcanology, an explosive eruption is a volcanic eruption of the most violent type. Such eruptions result when sufficient gas has dissolved under pressure within a viscous magma such that expelled lava violently froths into volcanic ash when pressure is suddenly lowered at the vent.
What is the biggest eruption ever?
On 10 April 1815, Tambora produced the largest eruption known on the planet during the past 10,000 years. The volcano erupted more than 50 cubic kilometers of magma and collapsed afterwards to form a 6 km wide and 1250 m deep caldera.
What are the two most violent eruptions?
Which volcanic eruptions were the deadliest?
| Eruption | Year | Casualties |
|---|---|---|
| Mont Pelée, Martinique | 1902 | 30,0001 (29,025)2 |
| Krakatau, Indonesia | 1883 | 36,0001 (36,417)2 |
| Tambora, Indonesia | 1815 | 92,0001,2 |
| Unzendake, Japan | 1792 | 15,0001 (14,030)2 |
What are the 3 types of volcano?
There are three types of volcanoes: cinder cones (also called spatter cones), composite volcanoes (also called stratovolcanoes), and shield volcanoes. Figure 11.22 illustrates the size and shape differences amongst these volcanoes.
What volcano could destroy the world?
Yellowstone supervolcano
The Yellowstone supervolcano is a natural disaster that we cannot prepare for, it would bring the world to its knees and destroy life as we know it. This Yellowstone Volcano has been dated to be as old as 2,100,000 years old, and throughout that lifetime has erupted on average every 600,000-700,000 years.

What was the biggest volcano ever erupted?
Mount Tambora
The explosion of Mount Tambora is the largest ever recorded by humans, ranking a 7 (or “super-colossal”) on the Volcanic Explosivity Index, the second-highest rating in the index. The volcano, which is still active, is one of the tallest peaks in the Indonesian archipelago.
What is the most powerful volcano on Earth?
Tambora – Indonesia – 1815 The explosion of Mount Tambora is the largest ever recorded by humans, ranking a 7 (or “super-colossal”) on the Volcanic Explosivity Index, the second-highest rating in the index.
Which is the most explosive type of volcano?
The most explosive volcanic eruptions are associated with the type of volcano Composite Cones. The main types of volcanoes consist of cinder cones, composite cones, and shield volcanoes. All three have different characteristics from the shape or type of eruption.
What kind of eruption is a vulcanian eruption?
A Vulcanian eruption is a short, violent, relatively small explosion of viscous magma (usually andesite, dacite, or rhyolite ). This type of eruption results from the fragmentation and explosion of a plug of lava in a volcanic conduit, or from the rupture of a lava dome (viscous lava that piles up over a vent).
What are the names of the volcanoes that erupt at night?
Strombolian eruptions are named for the volcano that makes up the Italian island of Stromboli, which has several erupting summit vents. These eruptions are particularly spectacular at night, when the lava glows brightly. Vulcanian eruption.
Which is the least violent volcano in the world?
They are one of the least violent of the explosive eruptions, although they can still be very dangerous if bombs or lava flows reach inhabited areas. Strombolian eruptions are named for the volcano that makes up the Italian island of Stromboli, which has several erupting summit vents.
