Types of Volcanic Eruptions
This is a quiet eruption with thin lava.
Hawaiian eruption
This is mud and rocks that flow down the mountain when part of the mountain collapses.
Debris flow
This is an avalanche of hot dust and gases produced during an eruption.
Pyroclastic Flow
Rocks push together causing a section of rock to move up at this type of fault.
Reverse fault
This is a hot spring that shoots hot water and steam into the air.
Geyser
This is a nonviolent eruption with lava that runs down the side of a volcano.
Strombolian eruption
This is volcanic gases.
Vog
This type of volcano has a recorded eruption and is not expected to erupt again.
Dormant
Rocks move apart in at this type of fault.
Normal fault.
This is a hot spring with mud that may bubble and give off gases.
Mud pot
This is an explosive eruption that shoots lava, ash, gas, and cinders into the air.
Vulcanian eruption
This is rock produced from cooled magma and lava.
Igneous rock
This type of volcano has a recorded eruption and is expected to erupt again.
Active
Rocks move horizontally past each other at this type of fault.
Strike-slip fault
This is water at the earth's surface that was heated by an underground magma pool.
Hot spring
This is a violent eruption that causes a pyroclastic flow.
Pelean eruption
These are precious stones that may be produced from a volcanic eruption.
Gems
This type of volcano has no recorded eruption and is not expected to erupt again.
Extinct
This is the point on the earth's surface directly above the focus.
Epicenter
A place where hot magma rises toward the earth's surface.
Hot spot
This volcanic eruption happens under water.
Submarine eruption
This product of volcanic eruptions helps enrich the soil and helps farmers grow crops.
Minerals
A volcano with gradually sloping sides that is usually not explosive.
Shield volcano
This type of seismic wave occurs below the earth's surface.
Body wave
This type of wave occurs at the earth's surface and is destructive.
