Are shield volcanoes loud or quiet?
Types and Examples. Different types of volcanoes tend to produce different types of eruptions. Shield volcanoes, those with broad, gentle slopes, produce the quietest eruptions. The Hawaiian Islands are not only home to active shield volcanoes, but the chain is actually built entirely by them.
What volcano is quiet and explosive?
Shield volcanoes, those with broad, gentle slopes, produce the quietest eruptions. The Hawaiian Islands are not only home to active shield volcanoes, but the chain is actually built entirely by them. The two most common types of volcanoes known for producing explosive eruptions are cinder cones and stratovolcanoes.
Is a shield volcano explosive or effusive?
Shield Volcano: A shield volcano has low levels of dissolved gas and silica in its magma. Its eruptions are effusive, and the fluid lava moves quickly away from the vent, forming a gently sloping volcano.
Does a shield cone form from a quiet eruption or an explosive eruption?
A quiet eruption of low-viscosity lava produces a wide, flat volcano called a shield volcano. If an eruption is entirely ash and cinders, the result will be a small, steep-sided volcano called a cinder cone.
Which volcano is the least explosive?
Shield volcanoes
Shield volcanoes tend to be the least explosive volcanoes. Most of the material they produce is lava, rather than the more explosive pyroclastic material.
What type of eruption is a shield volcano?
Eruptions at shield volcanoes are only explosive if water somehow gets into the vent, otherwise they are characterized by low-explosivity fountaining that forms cinder cones and spatter cones at the vent, however, 90% of the volcano is lava rather than pyroclastic material.
What is shield volcano type of eruption?
The style of eruption, structure and composition determine a volcano’s type. Shield volcanoes, such as Ambrym and Ambae, are characterised by a broad, flat and convex shape with a summit calderas. The eruptions consist of fluid lava flows, weak fountaining explosions, summit explosions and ash fall.
