Volcanoes typically have the most explosive eruptions?
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.
Generally not. Although explosive eruptions can happen, most eruptions from shield volcanoes are effusive.
Are cinder cones the most potentially dangerous volcanoes because they generate the most explosive eruptions?
No. Composite volcanoes, also called stratovolcanoes, are the most dangerous. They generally produce the largest explosive eruptions.
Occasionally, yes, but that is the exception rather than the rule. Most eruptions at shield volcanoes are effusive, but explosive phreatic eruptions, essentially steam explosions, can sometimes occur.
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.
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.
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.
The Yellowstone volcano has produced both explosive and effusive ("quiet") eruptions. The super eruptions for which it is most famous are explosive.
No. The most explosive variety of volcanic activity would be the caldera-forming eruptions of stratovolcanoes. Cinder cone eruptions are only mildly explosive.
Explosive volcanoes are most common at subduction zones.
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).
No. A supervolcano is a volcano that is capable of producing extremely large explosive eruptions. Kilauea is a shield volcano. Most of its eruptions are non-explosive or only mildly explosive.
A stratovolcano is the most explosive type...
Most explosive volcanoes are stratovolcanoes, also called composite volcanoes.
There are several ways to determine what type of eruption a volcano will have. However, the answer is not very straight forward. Although different types of volcanoes are known for different types of eruptions, they can produce other types of eruptions that they are not typically known for. For example, Hawaiian volcanoes, although known for their flowing lava and fire fountains have in recent years been discovered to have very explosive eruptions as well. Another… Read More
Most volcanoes on Earth are associated with boundaries of tectonic plates while those that we have seen on other planets are probably from hot spots. Earth's volcanoes also seem more prone to explosive eruptions, primarily due to the abundance of water on Earth.
Volcanic eruptions range from explosive to quiet depending on the viscosity of the magma & the amount of dissolved gases. Felsite volcanoes are the most viscous & the most explosives. The explosive products from a volcano are called pyroclastic rocks. Thus the most explosive volcano are those whose composition is felsitic.This viscous felsite may plug the vocano, causing the pressure to build within it. When the pressure becomes great, an explosive eruption will occur. That… Read More
Occasionally, yes. Most of Kilauea's eruptions are effusive, however.
it would most likely be explosive eruptions because the lava formed by an explosive eruption is very slow, it is more likely to harden at the top of the volcano.
No. Volcanic eruptions in Hawaii are not usually explosive.
volcanoes that have large amounts of silica The most explosive volcanoes are stratovolcanoes with felsic magama that has a high gas content. A. Shield Volcano- these usually form at hot spots and are like the ones in Hawaii. THey are nonexplosive because the lava is very runny. This would not be the most explosive. B. Cindercone-this would probably be your best bet although they erupt only once during their liftime. They are the smallest type… Read More
Explosive eruptions can involve any type of magma (underground molten rock). However, most explosive erutptions involve felsic or intermediate magma.
Rhyolitic (granitic) magma is usually associated with the most explosive eruptions.
What are the characterististicsc of the three types of volcanoes? <--- looser answer here's mine.. Shield volcanoes- their sides are not very steep. They have nonexplosive eruptions. Because the lava is very runny, it spreads out over a wide area. Over time, the layers of lava create a volcano that has gently sloping sides. Cinder Cone volcanoes- made of pyroclastic material usually produced from moderately explosive eruptions. This forms steep slopes. Cinder cones often occur… Read More
Rhyolite caldera complexes are the most explosive volcanoes, although other types of volcanoes can also erupt.
Shield volcanoes can produce pyrcoclastic flows, but it is rare. Shield volcanoes are fed by low-viscosity basaltic lava with a low gas content. The means that most eruptions are either non exposive or have a very low-grade explosivity. An eruption needs to be explosive to produce pyroclastic flows. However, records show that Kilauea has produced explosive eruptions with pyroclastic flows. The explosions appear to have been the result of groundwater seeping into the magma chamber.
Composite volcanoes are the most explosive.
Most eruptions from a cinder cone are explosive, though not very large.
Volcanoes with more viscosity are more explosive.
Magma is a hot fluid from deep within the Earth's crust. The set of magma conditions that produce the most explosive eruptions are high viscosity and the presence of dissolved gases.
Mount Fuji's eruption style is classified as explosive. Explosive style volcanoes typically shoot gas, dust, rocks, and pyroclatic material up into the air. They are considered one of the most dangerous styles.
Mount St. Helens is generally regarded as an explosive volcano, but like most stratovolcanoes, it can produce both explosive and non-explosive eruptions.
Generally not. Most eruptions in Hawaii are effusive.
Like most stratovolcanoes, Mount St Helens alternates between explosive and effusive eruptions.
If the magma has a high water content, then the volcano will most likely have an explosive eruption. Also, vocanoes can have explosive eruptions if the magma contains a large percentage of silica. Hope this helps!
Yes. The Yellowstone volcano has produced several VEI-8 eruptions, the most explosive level of eruption possible.

Cindercone volcanoes are small, steep sided, narrow based, loosely packed cones made entirely of pyroclastic material from moderately explosive eruptions. It's the classical and most common conically-shaped ("Triangular") form of volcano.
Most explosive volcanism is located at oceanic to continental subduction zones.
Four facts about stratovolcano: 1) Tall, conical, volcano built up by many layers of hardened lava, tephra, pumice, and volcanic ash 2) Characterized by a steep profile and periodic, explosive eruptions 3) Lava typically cools and hardens before spreading far due to high viscosity 4) Among the most common types of volcanoes
No. The most violent eruptions involve felsic magma.
In general, composite volcanoes are the most dangerous volcanoes because they are more explosive than the other types.
It is mostly covered with lava
high viscosity in magma composition.
There are two reasons. First, continental volcanoes are more likely than other volcanoes to be of the stratovolcano type. These volcanoes produce the largest, most explosive eruptions that pose the greatest risk to human lives and property. Second, since they are on the mainland, continental volcanoes are generally more likely to have people living near them. An eruption that occurs on an uninhabited island and does not affect anybody is not generally considered a disaster.
Magma that is high in viscosity (normally a felsic lava, high in silica) will produce explosive eruptions.
Most volcanoes form along the edges of Earth's tectonic plates. Also most volcanic eruptions are preceded by earthquakes.
Volcanic eruptions occur only in certain places and do not occur randomly. ... Volcanoes occur most frequently at plate boundaries
