Types of Eruptions

Question 1

This Volcanic eruption produces runny lava that floods the Earth’s surface through fissures, which can be up to 15 miles long.

Answer 1

Icelandic Eruption

Question 2

This volcanic eruption is characterized by numerous fissures and results in large quantities of hot, thin, and runny lava
that flows rapidly out of the main vent.

Answer 2

Hawaiian Eruption

Question 3

An eruption resulting from the interaction of new magma or lava with water and can be very explosive. The water can be from groundwater, hydrothermal systems, surface runoff, a lake or the sea.

Answer 3

Phreatomagmatic Eruption

Question 4

Short, explosive eruptions shoot thick and pasty lava, steam, and gas into the air, producing little to no lava. The resulting steep- sided cone is called a cinder cone.

Answer 4

Strombolian Eruption

Question 5

The most common type of volcanic cone, first the volcano will have an
explosive eruption that ejects huge amounts of steam, gas, and ash
followed by the ejection of lava. They are created from a combination of
eruptions forming layers of ash and lava.

Answer 5

Stratovolcanoes
(Composite)

Question 6

This eruption makes steam-driven explosions that occur when water beneath the ground or on the surface is heated by magma, lava, hot rocks, or new volcanic deposits.

Answer 6

Phreatic eruption

Question 7

This eruption makes a violent explosion resulting in the collapse of the volcano’s summit
and the release of a destructive pyroclastic flow. This flow is a
rapid and destructive mixture of hot ash, gas, and rocks that
annihilates everything in its path.

Answer 7

Pelean Eruption

Question 8

The most powerful eruption type, with a
towering ash cloud reaching up to 50,000 feet
(about 10 miles) in height, and extremely
dangerous pyroclastic flows.

Answer 8

Plinian Eruption
