11 – magma chamber. A magma chamber is a large pool of liquid rock beneath the surface of the Earth. The molten rock, or magma, in such a chamber is less dense than the surrounding country rock, which produces buoyant forces on the magma that tend to drive it upwards. [1]
The structure's magma chamber remains active as there apparently are solfataras, hot springs, gas emissions and frequent episodes of large-scale up- and downlift ground deformation do occur. [18] [19] In 2008 it was discovered that the Phlegraean Fields and Mount Vesuvius have a common magma chamber at a depth of 10 km (6.2 mi). [20]
It is the only volcano in the world where visitors can take an elevator and safely descend into the magma chamber. The magma that would filled the chamber drained away, revealing the void beneath the surface. [4] In August 2015, the members of the Icelandic band Kaleo and fourteen support staff descended into the volcano's magma chamber and ...

Sills are fed by dikes, [3] except in unusual locations where they form in nearly vertical beds attached directly to a magma source. The rocks must be brittle and fracture to create the planes along which the magma intrudes the parent rock bodies, whether this occurs along preexisting planes between sedimentary or volcanic beds or weakened planes related to foliation in metamorphic rock.
The fractures take the form of a set of concentric cones dipping at a relatively shallow angle into the magma chamber. [3] [13] When the caldera is subsequently emptied by explosive volcanic activity, the roof of the magma chamber collapses as a plug of rock surrounded by a ring fracture. Magma rising into the ring fracture produces a ring dike.
At the bottom of the magma reservoir, a cumulate rock forms. Cumulate rocks are the typical product of precipitation of solid crystals from a fractionating magma chamber. These accumulations typically occur on the floor of the magma chamber, although they are possible on the roofs if anorthite plagioclase is able to float free of a denser mafic ...
There is always the possibility of renewed volcanic activity if the magma chamber has not solidified [121] even if there is no positive evidence of ongoing magma generation. [122] Deep earthquake activity at Ciomadul occurs down to a depth of 70 kilometres (43 mi), indicating that the volcanic system between the magma chamber and lithospheric ...
