Kilauea Hawaii consists of a string of islands, or an archapelago. Kilauea is
the world?s most active volcanic craters. Craters are formed either by the
massive collapse of material during volcanic activity, by unusually violent
explosions, or later by erosion during dormancy (Comptons). It is situated on
is 1111 m (3646 ft.) above sea level. The crater has an area of about 10 sq.
km., which forms a great cavity in the side of the mountain. Volcanic activity
recently has been restricted to an inner crater called Halemaumau. Halemaumau
measures more than 900 m (about 3000 ft.) across and has a depth of about 400 m
volcano spews an average of 525,000 cubic yards of lava a day and by 1995 had
it had destroyed the visitors center at the national park, a stretch of Kalapana
Highway, and more than 65 houses by 1990. Kilauea is located on a hot spot under
the island, and the magma is thought to come from a depth of at least 50 km.

accumulates until it drains off into other subterranean passages. When greater
created by highly fluid basalt flows that spread over wide areas. The fluid
basalt usually only builds a cone around seven degrees steep. Over thousands of
years though, these cones can reach massive size, which is shown in the Hawaiian
Island volcanoes. The Hawaiian Islands are composed of shield volcanoes, that
have been built up from the sea floor. If measured from sea floor level, some of
1921, 1950, 1955, 1959, 1965, and 1969. The current eruption cycle, the
longest-running in modern Hawaiian history, began on January 3, 1983 (Encarta).
