English loves putting words together to make new ones. Times, Sunday Times (2009) Supervolcanoes are usually located at volcanic hotspots rather than at plate boundaries and their main feature is a large underground magma chamber.

Molten rock in the earth's crust. The least-dense magma rises to the top. Word Finder When magma rises along a deep fault and pours out on the earth's surface, it is termed lava. A magma chamber is a large underground pool of liquid rock found beneath the surface of the Earth.

Can be stacked with Combustion Rounds for a total of 180% Heat damage. Volcano: Definition The volcano is the fracture in the surface of planetary mass substances, which permits hot lava, volcanic ash and gases to come out from a magma chamber below the crust. Magma chamber definition is - the underground space usually deep below the earth's surface occupied by magma that may ascend from it to or toward the surface. Additionally, the removal of the lower melting point components will tend to make the magma more viscous (by increasing the concentration of silicates). This can dramatically increase pressures.

Also known as a magma storage zone or magma reservoir. The combination of regional extension, which lowers the maximum attainable overpressure on the chamber roof, and a large magma chamber with warm walls, which has a high effective viscoelasticity, may suppress rhyolite dike formation and allow such large chambers to fill with magma.[11].
