These eruptions have taken place from the main caldera and fissures along rift zones. They are generally fluid ( VEI -0) Hawaiian eruptions but more violent eruptions have occurred throughout Mauna Loa's eruptive history, with the largest recorded explosive eruptions having taken place in the 19th century.
Mauna Loa is a shield volcano with relatively gentle slopes, and a volume estimated at 18,000 cubic miles (75,000 km 3), [5] although its peak is about 125 feet (38 m) lower than that of its neighbor, Mauna Kea. [6] Lava eruptions from Mauna Loa are silica-poor and very fluid, and tend to be non-explosive.
