Fissure eruptions are also common on the flanks of many large volcanoes and, therefore, they are not restricted to areas undergoing regional extension. Magma-filled fissures radiating from the summit regions of active volcanoes like Mt. Etna, Mauna Loa, and Kilauea propagate outward from the central vent system. Extrusion from these propagating fissures can produce elongate volcano morphologies, such as those that are typical of many Hawaiian shield volcanoes. Note, for example, the axial elongation of the Mauna Loa shield volcano shown in the image to the left. Mauna Loa fissure eruptions are generated along two axial rift zones connected at the Mokuaweoweo summit crater. Each rift zone is underlain by magma-filled fissures. The image here displays several lava flows radiating downslope from these axial rift zones. Most of these erupted in historic times.

What type of eruption does basaltic magma have?
The type of volcano and eruption from basaltic magma would be a cinder cone volcano. The eruption would be a mild explosive eruption. It would be mainly ash and scoria.
Plinian eruptions are the most powerful type of eruption They are usually caused by what kind of magma?
Plinian eruptions are usually associated with felsic magmas.
What type of volcanic eruption depends on the amount of gases and the composition?
The type of volcanic eruption depends on the amount of gases and the composition of magma. In addition to the composition of the magma, the volcanic eruption depends on the ration of sulfur, carbon dioxide, and water the magma contains.
What type of magma causes quiet eruption?
magma that is low in silica which is thin and runny
What is the name of the opening in the Earth through which a volcano erupts?
A volcanic vent or fissure (depending on the type of eruption).
What type of eruption does basaltic magma have?
The type of volcano and eruption from basaltic magma would be a cinder cone volcano. The eruption would be a mild explosive eruption. It would be mainly ash and scoria.
What type of volcanic eruptions occur most often when plates are moving apart?
Most common would be a fissure eruption of basaltic magma.
Plinian eruptions are the most powerful type of eruption They are usually caused by what kind of magma?
Plinian eruptions are usually associated with felsic magmas.

What type of magma causes quiet eruption?
magma that is low in silica which is thin and runny
What properties of magma help determine the type of eruption?
The properties of magma that help to determine the type of eruption are the magma's viscosity and its silica content. Those volcanoes that exhibit massive eruptions have a high viscosity and high silica content.
What is the name of the opening in the Earth through which a volcano erupts?
A volcanic vent or fissure (depending on the type of eruption).
What type of magma is primarily associated with high viscosity?
Granitic magma
Rhyolite is associated with what type of eruption?
Rhyolite is associated with explosive eruptions.
Which set of magma conditions produces the most explosive eruptions?
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.
The type of magma that often causes a violent eruption can be described as having?
you smell
What are two type of volcanic vents?
magma or lava dried after a volcanic eruption.
