Kilauea

Kilauea (kē`läwā`ə), crater, 3,646 ft (1,111 m) deep, central Hawaii island, Hawaii, on the southeastern slope of Mauna Loa in Hawaii Volcanoes National Park. One of the largest active craters 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. The usual level of the lake of molten lava is c.740 ft (230 m) below the pit's rim.

Kilauea

Crater, eastern side of Mauna Loa, Hawaii Volcanoes National Park, U.S. The world's largest active volcanic crater, it is about 3 mi (5 km) long, 2 mi (3.2 km) wide, and 500 ft (150 m) deep, lying at an altitude of 4,090 ft (1,250 m). In its floor is the vent known as Halemaumau Pit, legendary home of the fire goddess Pele. Its frequent eruptions are usually contained within the vent as a boiling lake of lava, but occasionally the lava escapes; since 1983 a series of eruptions produced lava that reached the sea 30 mi (48 km) away.

Kilauea 

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.
