Which set of magma conditions produces the most explosive eruptions?

Magma that is high in silica content and gas bubbles is most likely to produce the most explosive eruptions. This type of magma creates high viscosity, which traps gas bubbles and builds up pressure until it violently explodes. These eruptions typically occur at stratovolcanoes like Mount St. Helens.


What type of magma that tends to cause explosive eruptions has a what?

Magma that tends to cause explosive eruptions is typically high in silica content, making it thick and viscous. This results in gas build-up and pressure within the magma chamber, leading to explosive eruptions.


What type of eruption does Colima produce?

Colima produces explosive eruptions, characterized by the sudden release of gas, ash, and magma. These eruptions can generate pyroclastic flows, lava flows, and volcanic ash plumes.


What type of eruption does MtFuji produce?

It is a composite volcano, so the kind of eruptions it has is explosive.


What type of magma does the eyjafjallajokull produce?

Eyjafjallajökull volcano in Iceland produces andesitic magma, which is a type of intermediate magma that has a silica content between basaltic and rhyolitic magmas. This type of magma can lead to explosive eruptions due to its high viscosity, gas content, and tendency to form pyroclastic flows.


What type of magma is the most powerful when it comes unleashing very explosive volcanic eruptions?

Basaltic


Which type of volcano has explosive eruptions due to thick magma which contains a large amount pf pressurized gas?

A stratovolcano, also known as a composite volcano, is the type of volcano that has explosive eruptions due to thick magma containing a large amount of pressurized gas. The build-up of pressure from the trapped gas within the viscous magma leads to explosive eruptions that can be highly destructive.


Plinian eruptions are the most powerful type of eruption They are usually caused by what kind of magma?

Plinian eruptions are caused by highly viscous magma with high eruptive column heights, explosive fragmentation of magma, and high gas content, often derived from silica-rich (silicic) magma. This type of magma tends to trap gases leading to highly explosive eruptions characteristic of Plinian events.


What type of eruption does rhyolitic magma produce?

Rhyolitic magma typically produces explosive volcanic eruptions due to its high viscosity and gas content. This type of magma can trap gases, leading to increased pressure that results in violent eruptions when released. These eruptions often produce pyroclastic flows, ash clouds, and lava domes, making them among the most hazardous volcanic events. Examples of such eruptions can be seen at locations like Yellowstone and Mount St. Helens.


What type of magma do highly explosive volcanoes have?

Highly explosive volcanoes typically have viscous, silica-rich magma known as rhyolitic magma. This type of magma contains high amounts of gas and is prone to causing explosive eruptions due to the trapped pressure within the magma chamber.


What type of magma causes quiet eruption?

Magma with low viscosity, such as basaltic magma, typically causes quiet eruptions. This type of magma flows easily and allows gases to escape, resulting in relatively gentle eruptions with less explosive activity.


Which type of volcano has explosive eruptions due to thick magma which contains large amount of pressurized gas?

the stratovolcano
