  2. 1815 eruption of Mount Tambora - Wikipedia

    en.wikipedia.org/wiki/1815_eruption_of_Mount_Tambora

    Mount Tambora experienced several centuries of dormancy before 1815, caused by the gradual cooling of hydrous magma in its closed magma chamber. Inside the chamber at depths between 1.5 and 4.5 km (5,000 and 15,000 ft), the exsolution of a high-pressure fluid magma formed during cooling and crystallisation of the magma.

    Submarine volcanoes are underwater vents or fissures in the Earth's surface from which magma can erupt. Many submarine volcanoes are located near areas of tectonic plate formation , known as mid-ocean ridges .

    Mount Mazama (Tum-sum-ne in the Native American language Klamath) is a complex volcano in the western U.S. state of Oregon, in a segment of the Cascade Volcanic Arc and Cascade Range. Most of the mountain collapsed following a major eruption approximately 7,700 years ago.

    en.wikipedia.org/wiki/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]

    Magma emplacement can take place at any depth above the source rock. Magma emplacement is primarily controlled by the internal forces of magma including buoyancy and magma pressure. Magma pressure changes with depth as vertical stress is a function of the depth. Another parameter of magma emplacement is the rate of magma supply.
