Kilauea is the most active volcano on Earth, and
one of the most intensely studied volcanoes in the world.
Kilauea is a shield volcano in the Hawaiian archipelago. It was and is being formed by a hot spot beneath the Pacific plate. Like other shield volcanoes, Kilauea's eruptions tend to be Hawaiian in type, but they can get dangerous. Several violent eruptions have had pyroclastic flows, large ashfalls, and lava bombs. Such an eruption in the eighteenth century killed many troops of a Hawaiian ruler.
A feature from these large, explosive eruptions is a caldera. Kilauea has a large Calderaat it's summit, and a smaller Halemaumau. Kilauea also has several side vents, on or around rift zones. These rift zones are to the SouthEast and SouthWest. Among the vents in those areas are; the famous Puu Oo, Mauna Ulu, and all the craters along chain of craters road.
Current volcanic activity began in 1983 and is the longest volcanic eruption of Kilauea in recorded time. This present eruption built up Pu'u O'o vent, and countless other volcanic vents.
