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 ...
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 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]
Geologists suggested that "pulses" of magma entering Mauna Loa's deeper magma system may have increased pressure inside Kīlauea and triggered the concurrent eruptions. [28] Mauna Loa began erupting on November 27, 2022, during Kīlauea's ongoing eruption, the first time since 1984 that both volcanoes were simultaneously erupting.
The Yellowstone Caldera, sometimes referred to as the Yellowstone Supervolcano, is a volcanic caldera and supervolcano in Yellowstone National Park in the Western United States. The caldera and most of the park are located in the northwest corner of the state of Wyoming. The caldera measures 43 by 28 miles (70 by 45 kilometers), and postcaldera ...
Note person for scale. Cave of the Crystals or Giant Crystal Cave (Spanish: Cueva de los cristales) is a cave connected to the Naica Mine at a depth of 300 metres (980 ft), in Naica, Chihuahua, Mexico. It takes the form of a chamber within the limestone host rock of the mine, and is about 109 metres (358 ft) long with a volume of 5,000 to 6,000 ...
Today, the Christmas Mountains caldera complex, as well as the dome, is heavily eroded, exposing the deep structure of the complex. The complex is the type location for laccocalderas. Laccocalderas differ from conventional calderas, being relatively small and developing over thin, shallow laccolithic magma chambers rather than deeper bodies ...
