Large explosive eruptions are generally characteristic of stratovolcanoes.
There are three types of volcanoes, shield volcanoes, composite volcanoes, and cinder cone volcanoes. Composite volcanoes contain the highest viscosity making them the most explosive volcanoes.
Large explosive eruptions are generally characteristic of stratovolcanoes.
A stratovolcano is the most explosive type...
No. The most explosive variety of volcanic activity would be the caldera-forming eruptions of stratovolcanoes. Cinder cone eruptions are only mildly explosive.
Very rarely. Shield volcanoes are formed from the eruption of low-viscosity, gas-poor magma which has very little potential to explode. On rare occasions explosive eruptions may occur when magma comes in contact with groundwater.
Volcanoes don't, but volcanic eruptions do. Volcanic eruptions are rated by Colcanic Explosivity Index or VEI based on the volcume of material ejected. It ranges from VEI-0 for the non-explosive eruption of lava to VEI-8 for the most violent eruptions of supervolcanoes.
Shield volcanoes have effusive eruptions. Effusive eruptions are a volcanic phenomenon; in some ways the opposite of explosive eruptions. An effusive eruption is characterized by an outpouring of low viscosity lava which has a fairly low volatile content. Usually, shield volcanoes have effusive eruptions.
Explosive volcanoes are most common at subduction zones.

Cinder cone volcanoes are made of pyroclastic material and most often form from moderately explosive eruptions.

Generally not. Explosive eruptions may happen occasionally, but most eruptions are effusive.

Yes. The Yellowstone volcano has produced several VEI-8 eruptions, the most explosive level of eruption possible.
A composite volcano is the most explosive type of volcano there is. Mt. St. Helens and Mt.Vesuvious in Pompeii are both examples of composite volcanoes, and look at the damage they did. a composite volcano usually has pyroclastic flows to accompany the traditional lava and ash.
Volcanoes come in many types, such as scoria volcanoes (mafic, small, not very explosive),shield volcanoes (large, mafic, mild eruptions of large volumes of lava), composite volcanoes (large, traditional cone shape, most deadly), lava domes (felsic, explosive, usually found with other volcanoes), fissures ( lava erups through fractures, mafic), and canderas (steep-walled depression, very large).
are also known as Strato volcanoes. They are the most common type of volcano, and are formed by explosive eruptions of pyroclastic material followed by a quiet outpouring of lava.
No. Volcanic eruptions in Hawaii are not usually explosive.
