By January 2005, 2.7 cubic kilometers (0.65 cu mi) of magma covered an area of more than 117 square kilometers (45 sq mi) and added 230 acres (0.93 km 2) of land to the southeast coast of Hawaiʻi. The eruption claimed at least 189 buildings and 14 kilometers (8.7 mi) of highways, as well as a church, a store, the Wahaʻula Visitor Center, and ...
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 ...
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 ...
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 ...
Plinian eruption. Plinian eruption: 1: ash plume; 2: magma conduit; 3: volcanic ash fall; 4: layers of lava and ash; 5: stratum; 6: magma chamber. 1822 artist's impression of the eruption of Mount Vesuvius in 79, depicting what the AD 79 eruption may have looked like, by the English geologist George Julius Poulett Scrope.
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 ...

[7] The top of the seamount is about 3,200 ft (975 m) below sea level.
