Many have rhyolitic magma, which is high in silica. Magma with higher viscosity and higher gas content is the most explosive when released.

What type of magma do high explosive volcanoes have?
Viscous, gaseous magma, usually of high acidity as compared to basalt.
Higly explosive volcanoes tend to have what type of magma?
Magma with high silica, high viscosity, and higher gas content.
Is a shield volcano non explosive or explosive?
Shield volcanoes are generally not explosive. However, soemtimes a type of explosive event called a phreatic eruption can occur if the magma comes in contact with water.
What type of volcano has magma that contains large volumes of gases but not silica and water?
The most explosive type of volcano, which is the type that has water, is called a boiler volcano. All active volcanoes have magma, and emit carbon dioxide. Magma can contain silica.
What determines the strength of a volcanic eruption?
The explosiveness of a volcano is determined by two factors. The obstacles in the magma's path and the type of volcano. When there is chunks of rock and hardened magma in the vent the liquid magma builds up until it sprays out at hufe ferocity. If there is little or no debris then the magma simply spews out. As for the type of volcano when the tectonic plates move apart it forms a row of GENTLE volcanoes but when they crash together the volcanoes are much more explosive.

What type of magma is found on composite volcano?
The average composition of magma in a composite volcano is andesitic. Composite volcanoes are highly variable though. They can erupt anything from basalt to rhyolite.
Volcanoes typically have the most explosive eruptions?
Large explosive eruptions are generally characteristic of stratovolcanoes.
What type of magma will produce explosive eruptions?
Felsic magmas that are high in silica content and are highly viscous produce explosive eruptions.
Which type of magma causes quiet volcanoes?
magma that is low on silica & thin and runny & it flows easily
What type of volcanic rock do you find in a explosive volcano?
Explosive volcanoes can produce pumice and tuff.
What type of magma that tends to cause explosive eruptions has a what?
High temperature
What kind of magma produce violent volcanoes eruptions?
Rhyolitic magma. This type of magma is found where the gases can't escape like in volcanic eruptions. Because the gas can not escape, the magma becomes viscous, resulting in the explosions being violent and unpredictable. The other type of magma is Basaltic magma. This can be found where continent plates are pulling away from each other and the magma is nearer the surface. This allows the gas to escape and therefore the magma is less viscous and doesn't result in explosive volcanoes, here eruptions are gentle and 'rifts' are more likely, where lava is persistent. I hope this helps! :)
