Kola Superdeep Borehole. The Kola Superdeep Borehole SG-3 (Russian: Кольская сверхглубокая скважина СГ-3, romanized: Kol'skaya sverkhglubokaya skvazhina SG-3) is the deepest human-made hole on Earth, which attained maximum true vertical depth of 12,262 metres (40,230 ft; 7.619 mi) in 1989. [1] It is the result of ...
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 ...
Pele's hair (closest modern Hawaiian translation: " lauoho o Pele " [1]) is a volcanic glass formation produced from cooled lava stretched into thin strands, usually from lava fountains, lava cascades, or vigorous lava flows. It is named after Pele, the Hawaiian goddess of volcanoes. [2]
The Hōei quake caused stress and compression of the magma chambers underneath Mount Fuji, leading to the eruption. A dike system stretches from the surface of Mount Fuji to 20 km into the subsurface. At 8 km depth, there are magma chambers of a dacitic and andesitic nature while at the deepest portion of the dike, a basaltic melt is located. [4]
Volcanic and igneous plumbing systems (VIPS) consist of interconnected magma channels and chambers through which magma flows and is stored within Earth's crust. [ 1] Volcanic plumbing systems can be found in all active tectonic settings, such as mid-oceanic ridges, subduction zones, and mantle plumes, when magmas generated in continental ...
Lassen Peak (/ ˈlæsən / LASS-ən), [3] commonly referred to as Mount Lassen, is a 10,457 ft (3,187 m) lava dome volcano in Lassen Volcanic National Park in Northern California. Located in the Shasta Cascade region above the northern Sacramento Valley, it is the southernmost active volcano in the Cascade Range of the Western United States ...
Like many other European peoples, it had buried its dead in excavated underground chambers, such as the Tomb of the Capitals, and less complex tumuli. In contrast, the original Roman custom had been cremation of the human body, after which the burnt remains were kept in a pot, urn, or ash-chest, often deposited in a columbarium or dovecote ...
Volcanic pipe. Volcanic pipes or volcanic conduits are subterranean geological structures formed by the violent, supersonic eruption of deep-origin volcanoes. They are considered to be a type of diatreme. Volcanic pipes are composed of a deep, narrow cone of solidified magma (described as "carrot-shaped"), and are usually largely composed of ...
