Kilauea(kē`läwā`ə), volcano and caldera, 3,646 ft (1,111 m) deep, central Hawaii island, Hawaii, on the southeastern slope of Mauna Loa in Hawaii Volcanoes National ParkHawaii Volcanoes National Park,
209,695 acres (84,926 hectares), on Hawaii island, Hawaii; est. 1916. The park contains two of the most active volcanoes in the world—Kilauea with its fiery pit crater, called Halemaumau, and Mauna Loa with the active Mokuaweoweo crater on

One of the largest active calderas in the world, Kilauea has a circumference of c.8 mi (13 km) and is surrounded by a wall of volcanic rock 200 to 500 ft (61–152 m) high. In its floor is Halemaumau, a fiery pit crater. The usual level of the lake of molten lava is c.740 ft (230 m) below the pit's rim. Although most recent eruptions have involved relatively quiet lava flows, often from vents on the volcano's flanks, Kilauea has erupted explosively for long periods in the past 2,500 years, and it can produce pyroclastic flows. Its most recent eruption began in 1983, with significant lava flows (most recently in 2018) from vents on its flanks at times.
an active volcano on the island of Hawaii in the Pacific Ocean. Altitude, 1,247 m. The gently sloping shield-shaped cone of Kilauea ends in a caldera 4.5 km in diameter and more than 230 m deep, in which the lava caldron of Halemaumau is located. Halemaumau is covered with a layer of solidified lava. Fountains of molten lava of basic composition erupt from cracks in the lava crust. The last significant eruptions occurred in 1952, 1954, and 1955.
