It moves in slow-moving balloons or diapirs; or in planar fractures (dikes). Sometimes it pools at the base of the crust, and other times it continues to rise to form magma chambers. WebIf a magma has low viscosity (it is runny), gas can escape easily, so when the magma erupts at the surface it forms lava flows. These eruptions are (relatively!) gentle, effusive eruptions.

WebMost dome eruptions are preceded by explosive eruptions of more gas rich magma, producing a tephra cone into which the dome is extruded. Volcanic domes can be extremely dangerous. because they form unstable slopes that may collapse to expose gas-rich viscous magma to atmospheric pressure. Lava domes evolve unpredictably, due to non-linear dynamics caused by crystallization and outgassing of the highly viscous lava in the dome's conduit. Domes undergo various processes such as growth, collapse, solidification and erosion. Lava domes grow by endogenic dome growth or exogenic dome growth.
