Kazumura Cave is a lava tube and has been surveyed at 40.7 miles (65.5 km) long and 3,614 feet (1,102 m) deep making it the longest and deepest lava tube in the world. [note 1][2][3] The cave is located on the island of Hawaiʻi on the eastern slope of Kīlauea. Kīlauea is the most recently active volcano on the Big Island.
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 ...
The Hilina slump is sliding seaward on top of the southern flank of the Kīlauea volcano, at an average speed of 10 cm/year (3.9 in/year). Kīlauea is the southeastern portion, about 13.7%, of the Big Island of Hawaii. Compared to the 25,000 to 35,000 cubic kilometers (6,000 to 8,400 cu mi) volume of Kīlauea, the submarine slide is between ...
Pele's tears (closest Hawaiian translation: "nā waimaka o Pele") are small pieces of solidified lava drops formed when airborne particles of molten material fuse into tearlike drops of volcanic glass. Pele's tears are jet black in color and are often found on one end of a strand of Pele's hair. Pele's tears is primarily a scientific term used ...
The Hawaiian shield volcanoes are not located near any plate boundaries; the volcanic activity of this island chain is distributed by the movement of the oceanic plate over an upwelling of magma known as a hotspot. Over millions of years, the tectonic movement that moves continents also creates long volcanic trails across the seafloor.
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.
Gardner Pinnacles Gardner. The island is made up of basalt rock, [6] which comes from lava erupted between 14 and 12 million years ago. [2] [c] The rock is dark grey and dense, [6] and has a high forsterite content implying the magma source was at 1,703 ± 56 °C (3,097 ± 101 °F).
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 ...
