Its many craters include Kilauea and Mokuaweoweo, two of the world's largest active craters. Mauna Loa has erupted three times (1942, 1949, 1975) since its period of greatest activity in 1881. Its lava flows have reached the sea.

Mauna Loa

Volcano, south-central Hawaii island, Hawaii, U.S. Located in Hawaii Volcanoes National Park, it is one of the world's largest mountain masses. It rises to 13,678 ft (4,169 m) and has a dome 75 mi (120 km) long and 64 mi (103 km) wide. Mokuaweoweo, its pit crater, has an area of nearly 4 sq mi (10 sq km) and a depth of 500–600 ft (150–180 m). It has averaged one eruption every 3.5 years since 1832. Many of its eruptions are confined within Mokuaweoweo; others are from fissures and vents. Its lava flows occupy more than 2,000 sq mi (5,120 sq km) of the island. See also Kilauea.

Mauna Loa 

(Hawaiian literally “long mountain”), an active shield volcano on the island of Hawaii. Elevation, 4,170 m. If the elevation of its underwater foundation, which lies at a depth of about 4,500 m, is taken into account, it is the earth’s highest volcano and largest in volume. Mauna Loa is composed of basalts. It has gentle slopes and a crater measuring about 6.5 km in circumference. Eruptions are frequent, with the last powerful one occurring in 1950. During eruptions a lava lake appears in the crater and lava flows pour out onto the slopes through cracks. The windward northern and northeastern slopes are covered by greatly diminished tropical rain forests. The leeward slopes are covered by sparse forests and savannas. There are plantations of pineapples, bananas, sugar-cane, and coffee trees on the volcano. It is the site of the Hawaii Volcanoes National Park, where tropical flora is preserved. A volcanologic station is situated on Mauna Loa.
