Kilauea
Hawaii's shield volcano, among the most active on Earth
On the southeastern flank of the Big Island of Hawaii, the land itself is being born. Kilauea is one of the most active volcanoes on the planet, a low, broad shield that has spent much of the past four decades in near-continuous eruption, paving over roads, devouring neighbourhoods and adding fresh acres of black rock to the Hawaiian coast. Unlike the explosive cones of the Pacific Rim, Kilauea mostly oozes and fountains, producing rivers of glowing lava that draw scientists and spectators to one of the few places where a volcano can be watched safely at work.
Kilauea rises only about 1,222 metres, dwarfed by its giant neighbour Mauna Loa, but its low profile is the signature of a basaltic shield volcano built from countless fluid lava flows. It sits over the Hawaiian hotspot, a plume of hot mantle rock that has punched a chain of islands across the moving Pacific plate. Its summit holds the Halemaumau crater, long home to a churning lava lake, while its East Rift Zone funnels magma toward the sea. In 2018 a dramatic eruption drained the summit lava lake, triggered the volcano's largest collapse in two centuries and sent flows pouring through the Puna district.
To Native Hawaiians, Kilauea is the home of Pele, the goddess of volcanoes and fire, and its eruptions carry deep cultural meaning rather than mere geological interest. Much of the volcano lies within Hawaii Volcanoes National Park, a World Heritage Site where visitors can hike across hardened lava and peer into a steaming caldera. The U.S. Geological Survey's Hawaiian Volcano Observatory, perched on its rim, has made Kilauea a cornerstone of modern volcano monitoring, refining the science of forecasting eruptions one flow at a time.
