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] If the magma finds a path to the surface, then the result will be a volcanic eruption ...
The magma that would normally fill the chamber and become sealed is believed to have drained away, to the bewilderment of scientists, revealing the rift 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 recorded a live rendition of the band ...
Magma is produced by melting of the mantle or the crust in various tectonic settings, which on Earth include subduction zones, continental rift zones, [5] mid-ocean ridges and hotspots. Mantle and crustal melts migrate upwards through the crust where they are thought to be stored in magma chambers [6] or trans-crustal crystal-rich mush zones. [7]
The magma subsequently broke through to the surface as plinian eruptions, followed by caldera collapse. Four calderas, all 1–1.5 kilometers (0.6–0.9 mi) in diameter, have been identified at the surface of the dome, and five sequences of volcaniclastic , tuff , and lava beds have been identified around the dome.
The earthquake affected both Kanagawa and Shizuoka prefectures, and was measured as an 8.2 on the Richter Scale. The Genroku earthquake had a similar effect on Mt. Fuji as Hoei but with less severity. It clamped the dike of the mountain at 8 km to the surface (where the dacitic magma resides), as well as the basaltic chamber at 20 km deep.

The 9 October 2008 issue of the journal Science suggested that two interconnected magma chambers lie beneath the surface of the volcano on Montserrat – one six kilometres below the surface and the other 12 kilometres (7.5 mi) below the surface. The journal also showed a link between surface behaviour and the size of the deeper magma chamber.
