Hawaiian eruption: 1, ash plume; 2, lava fountain; 3, crater; 4, lava lake; 5, fumarole; 6, lava flow; 7, layers of lava and ash; 8, stratum; 9, sill; 10, magma conduit; 11, magma chamber; 12, dike. A Hawaiian eruption is a type of volcanic eruption where lava flows from the vent in a relatively gentle, low level eruption; it is so named ...
1940 – U.S. Coast and Geodetic Survey chart number 4115 [5] First visit. 1978 [5] Kamaʻehuakanaloa Seamount[6] (previously known as Lōʻihi) is an active submarine volcano about 22 mi (35 km) off the southeast coast of the island of Hawaii. [7] The top of the seamount is about 3,200 ft (975 m) below sea level.
Entrance to the lava tube. Kaumana Cave is a lava tube created by a 1881 lava flow from Mauna Loa. [1] The tube has been surveyed at 2.026 miles (2197 m) long making it the 57th longest lava tube in the world.
Basaltic rock. 200km. 124miles. South Arch. Location south of the Hawaiian Islands. South Arch volcanic field is an underwater volcanic field south of Hawaiʻi Island. It was active during the last 10,000 years, and covers an area of 35 by 50 kilometres (22 mi × 31 mi) at a depth of 4,950 metres (16,240 ft). Although the field is related to ...
Kazumura Cave hosts a number of endemic cave arthropods found only on the island of Hawai'i, including a blind planthopper which feeds on the roots of native ʻōhiʻa trees (Oliarus polyphemus), a cave cricket (Caconemobius varius), a millipede, two species of Schrankia moths, an earwig, several species of spiders, and a unique cave-adapted water treader (Cavaticovelia aaa).

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 ...
Magma (sometimes colloquially but incorrectly referred to as lava) is found beneath the surface of the Earth, and evidence of magmatism has also been discovered on other terrestrial planets and some natural satellites. [3] Besides molten rock, magma may also contain suspended crystals and gas bubbles.
The composition of the soil found on Vikram’s landing site is consistent with an ancient magma ocean, the authors conclude. When analyzing the soil, the researchers found a relatively uniform ...
