What are the types of volcanism?
Strictly speaking there are two broad types of volcano, a stratovolcano and a shield volcano, although there are lots of different volcanic features that can form from erupted magma (such as cinder cones or lava domes) as well processes that shape volcanoes.
What are the 9 types of volcanic eruption?
Types of eruptions
- Hydrothermal eruption. An eruption driven by the heat in a hydrothermal systems.
- Phreatic eruption. An eruption driven by the heat from magma interacting with water.
- Phreatomagmatic eruption.
- Lava.
- Strombolian and Hawaiian eruptions.
- Vulcanian eruptions.
- Subplinian and Plinian eruptions.

What type of lava is Eyjafjallajökull?
Eyjafjallajokull volcano is considered a stratovolcano. What this means is that it’s a conical volcano built over time by layers of various volcanic materials. Black hardened lava, volcanic ash, pumice rock, and tephra fragments all combine to form different stratified colors and textures.
What are four types of volcanic eruptions?
There are four types of eruptions with properties determined mostly by the silica content of magma, and the amount of gas it contains. In order of increasing explosiveness, these are Hawai’ian, Strombolian, Vulcanian, and Plinian eruptions.
What type of volcano is Montserrat?
stratovolcano
Soufriere Hills is a stratovolcano made from alternating layers of hardened ash, lava, and rock. Except for a 17th-century eruption, the volcano remained quiet in historical times before resuming activity in 1995. In 1997, the volcano destroyed Montserrat’s capital city of Plymouth.
Is eyjafjallajökull convergent or divergent?
Eyjafjallajokull Formation Eyjafjallajokull was formed in two ways: by the divergent plate boundary intersecting Iceland and a hotspot that scientists believe resides under the boundary. Therefore, its height is due to the bubbling up magma from the boundary and its explosiveness is due to the hotspot.
