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 else can I help you with?
What type of magma does surtsey have?
Surtsey has basaltic magma, which is associated with the eruption of shield volcanoes. This type of magma is characterized by its low silica content and fluidity, allowing it to flow easily to the surface and form lava flows.
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 magna has a low silica content?
Magma with low silica content is typically referred to as mafic magma. Mafic magma is characterized by its high temperature and low viscosity, which allows for the eruption of lava flows. This type of magma is commonly associated with basaltic rocks.
What is a eruption from the side of a volcanano?
An eruption from the side of a volcano, often referred to as a flank eruption, occurs when magma escapes through a fissure or vent on the side of the volcano rather than from the summit. This type of eruption can produce lava flows, ash, and pyroclastic material, potentially affecting areas adjacent to the volcano. Flank eruptions can be less explosive than summit eruptions but can still pose significant hazards to nearby communities and ecosystems. Such eruptions are commonly associated with shield volcanoes and stratovolcanoes.
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 volcanic eruptions occur most often when plates are moving apart?
Most common would be a fissure eruption of basaltic magma.

A volcanic vent or fissure (depending on the type of eruption).
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 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 eruption produces a viscous magma containing 53 percent silica and a gas content of 2 percent?
A type of eruption that produces a viscous magma with 53 percent silica and a gas content of 2 percent is typically associated with a stratovolcano or a composite volcano. These eruptions are explosive due to the high viscosity of the magma, leading to the buildup of gas pressure before an explosive release. Example volcanoes with this type of eruption style include Mount St. Helens in the United States and Mount Pinatubo in the Philippines.
The type of magma that often causes a violent eruption can be described as having?

What are two type of volcanic vents?
magma or lava dried after a volcanic eruption.
