Felsic magmas that are high in silica content and are highly viscous produce 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.
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.
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.
It is a composite volcano, so the kind of eruptions it has is explosive.
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.

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.

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 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.
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.
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.
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.
