Generally not. Explosive eruptions may happen occasionally, but most eruptions are effusive.
shield volcanoes are only explosive if water somehow gets into the vent
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.
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.
No. A stratovolcano is a volcano with steep slopes consiting of layers of lava flows, ash, and pumice and is prone to explosive eruptions. A shield volcano is a volcano with broad slopes composed of layers of low viscosity lava flows and is generally not prone to explosive eruptions.
Mount Fuji is a stratovolcano, which is a composite volcano formed by both lava flows and explosive eruptions. It is not a cinder cone or shield volcano.
A broad volcano with gently sloping sides describes a shield volcano. These types of volcanoes are characterized by their low, wide profile and are formed by the slow accumulation of fluid lava flows over time, which create a shield-like shape. This type of volcano tends to have non-explosive eruptions due to the low viscosity of the lava.
Generally shield volcanoes do not explode. They erupt in a non-explosive fashion, fountaining or oozing lava.
Cinder cones are small and steep-sloped, composed of volcanic cinders, and have mildly explosive eruptions. Shield volcanoes are large and shallow-sloped with very runny lava and generally non-explosive eruptions.
Kilauea is a shield volcano fed by gas-poor basaltic magma. It is the gas in the magma that makes eruptions explosive. Kilauea has occasionally produced explosive eruptions when magma cam in contact with water.
Belknap volcano is a shield-type volcano. Shield volcanoes have low, broad profiles due to the fluid lava that flows easily over long distances from the vent. They are typically associated with non-explosive eruptions.
The case in question: eyjafjallajokull is a glacier. It is on a volcano, which is a shield volcano. A shield volcano has gentle sides. This defines a shield volcano. I hope this answers your question.
It's a shield volcano. Curtesy of a quick google search [from geography.learnontheinternet.co.uk] Shield Volcanoes Eruptions are typically non-explosive. Shield volcanoes produce fast flowing fluid [lava] that can flow for many miles. Eruptions tend to be frequent but relatively gentle.
