Large explosive eruptions are generally characteristic of stratovolcanoes.
What else can I help you with?
Cinder cones are the most potentially dangerous volcanoes because they generate the most explosive eruptions?
While cinder cones do have the potential for explosive eruptions, they are generally considered less dangerous than stratovolcanoes due to their smaller size and lower frequency of eruptions. Stratovolcanoes can produce more violent and destructive eruptions.
Which type of volcanoes have the most eplosive eruptions hawaiian hotspot rift zone subduction zone?
Subduction zone volcanoes typically have the most explosive eruptions. This is due to the accumulation of water and other volatile materials in the subducting tectonic plate, which leads to the generation of more viscous magma that can trap gas. In contrast, Hawaiian hotspot volcanoes and rift zone eruptions generally produce less explosive, basaltic lava flows.
Are shield volcanoes 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.
How many eruptions did mount stromboli have had in history?
Mount Stromboli has had continuous eruptions for about 2,000 years, making it one of the most active volcanoes in the world. It typically experiences small explosive eruptions every 20 minutes to a few hours, with occasional more significant eruptions.
Cinder cones are the most dangerous volcanoes?
Cinder cones are typically small volcanoes that have short and relatively mild eruptions compared to larger composite volcanoes or stratovolcanoes. While they can erupt with explosive force, their eruptions are usually confined to the immediate area surrounding the cone and do not pose as much risk to human populations as other types of volcanoes.

How do cinders form?
Cinder cone volcanoes are made of pyroclastic material and most often form from moderately explosive eruptions.
Do volcanoes have a scale magnitude?
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.
What is the most common VEI for volcanoes in Hawaii?
0 to 1, 0 being more common than 1. The reason is that Hawaiian volcanoes aren't very explosive. They produce a lot of lava, but with a continuous flow. VEI index measures explosiveness, with indicators for eruption column height and volume of pyroclastic material produced. Both factors are low for Hawaiian volcanoes.
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 is the most common type of volcano found on Earth?
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).
Is a shield volcano explosive or not?
Generally not. Explosive eruptions may happen occasionally, but most eruptions are effusive.
Where are the most explosive volcanoes subduction zones or rift zones?
Explosive volcanoes are most common at subduction zones.
