Why did the Lassen peak volcano erupt?
Mt. Lassen is a lava dome type of volcano. The domes of lava dome volcanoes grows from within, and commonly occur within the craters or on the flanks of large composite volcanoes.
Is a dome volcano the same as a cone volcano. if not - what is a dome volcano?
a dome volcano is not the same as a cone volcano. a dome volcano is a type of volcano, is a roughly circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano. Usually it extrudes very slowly, but constantly. A cone volcano has an appearance of an upside-down funnel with a hole in the top which the lava shoots out of.
What type of plate boundary is a lava dome volcano on?
A lava dome volcano is typically found at convergent plate boundaries, where two tectonic plates are colliding. The magma from the volcano is usually thick and sticky, causing it to build up and form a dome-shaped structure.
What is a plug dome volcano?
A plug dome volcano is a type of volcano that forms when sticky lava accumulates around a central vent, creating a steep-sided dome-shaped structure. These volcanoes are characterized by their viscous lava flows and explosive eruptions due to the pressure buildup beneath the dome. Plug dome volcanoes are typically found in subduction zones where water-rich magma interacts with continental crust.
What is a lava dome volcano?
Lava starts building up underneath some surface (solid) materials. It is being pushed up by some underground forces. The upward pressure causes a dome like cap covering the 'liquid' lava. Eventually the lava breaks through and you have a volcanic eruption.
Is lava dome a type of volcano?
Not exactly. Some volcanoes do consist of simply a lava dome, but most lava domes are found in or on stratovolcanoes.

What type of volcano is El Chichonal?
It is classified as a lava dome.

What type of rocks come out of a lava dome volcano?
Usually rhyolite or dacite.

What type of lava does a lava dome hold?
A lava dome holds very viscous lava, which is why it forms a dome rather than flowing away. Usually it is rhyolite or dacite.
What is an acid lava volcano?
Acid Lava Dome is a type of volcano that forms when viscous acid lava solidifies quickly to form a volcano with steep convex sides.
What type of lava forms the Lascar volcano?
The Lascar volcano forms basaltic lava, which is low in viscosity and typically erupts explosively, creating lava fountains, flows, and pyroclastic material.
This type of volcano forms from lava eruptions and tephra deposits forming a towering volcano.?
Composite
