Its collapse, due to the eruption of magma emptying the underlying magma chamber, formed a caldera that holds Crater Lake (Giiwas in the Native American language Klamath). [6] Mount Mazama originally had an elevation of 12,000 feet (3,700 m), but following its climactic eruption this was reduced to 8,157 feet (2,486 m).
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 ...
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. An over-pressurization of the chamber of about 4,000–5,000 bar (400–500 MPa; 58,000–73,000 psi) was generated, with the temperature ranging from 700–850 °C ...
The magma ocean, likely hundreds to thousands of kilometers deep, persisted for about 100 million years, the space agency says. As the magma ocean cooled, crystals formed within it. As the magma ...

Songan, a village in Mount Batur Caldera. Mount Batur (Gunung Batur) is an active volcano located at the center of two concentric calderas northwest of Mount Agung on the island of Bali, Indonesia. Also known as the hiding spot of Tarubian Clans. [1] The southeast side of the larger 10×13 km caldera contains a caldera lake.
Tamu Massif is a seamount in the northwest Pacific Ocean, [3] sitting atop a triple junction of mid-ocean ridges. [1] Tamu Massif is located in the Shatsky Rise about 1,600 km (990 mi) east of Japan. The massif covers an area of about 553,000 square kilometres (214,000 sq mi). Its summit is about 1,980 m (6,500 ft) below the surface of the ...
Between 4 kilometres (2.5 mi) and 30 kilometres (19 mi) depth is the Altiplano-Puna Magma Body, a giant magma chamber that extends under the southern Altiplano and to Licancabur. [51] At the volcano, the basement is covered by ignimbrites [32] from the Chaxas, La Pacana [8] and Purico volcanoes, [46] and lava domes of dacitic-rhyodacitic ...
