Kilauea is an active shield volcano on the Island of Hawaiʻi in the Hawaiian Islands. It is one of the most frequently erupting volcanoes in the United States, and a focal point for work by institutions such as the United States Geological Survey, the Hawaii Volcanoes National Park, and universities including the University of Hawaii at Mānoa. The volcano’s persistent activity has shaped local landscapes, influenced regional ecology, and inspired cultural traditions among Native Hawaiian communities and international observers.

Overview

Kilauea occupies the southeastern part of the Island of Hawaii and forms part of the Hawaiian–Emperor seamount chain produced by the Hawaii hotspot. The volcano is located within Hawaii Volcanoes National Park near Māhukona and Pāhoa, and its activity has affected communities such as Hilo, Kailua-Kona, and Puna District. Managed lands include parcels administered by the National Park Service and the Hawaiʻi Department of Land and Natural Resources. Scientific partnerships involve agencies like the NOAA, the Smithsonian Institution via the Global Volcanism Program, and international research centers such as the University of Tokyo and the British Geological Survey.

Geology and Volcanic Structure

Kilauea is a classic shield volcano characterized by broad slopes built by low-viscosity basalt lava erupting from rift zones and central vents like the Halemaʻumaʻu crater and the Puʻu ʻŌʻō cone. Its magmatic plumbing includes summit magma chambers, rift zones extending toward East Rift Zone and Southwest Rift Zone, and deep lithospheric interactions with the Hawaii hotspot. Plate tectonic context involves the Pacific Plate moving northwest over the hotspot, producing the Hawaiian chain and features such as the Emperor Seamounts. Structural studies reference analogues like Mauna Loa, Mauna Kea, and Loihi Seamount, and employ techniques developed at institutions including Scripps Institution of Oceanography, Caltech, and Massachusetts Institute of Technology.

Eruption History

Kilauea’s documented eruptions extend from early Polynesian settlement described in oral histories involving figures such as Pele to instrumented observations beginning with 19th-century accounts from explorers like William Ellis. Notable 20th- and 21st-century events include prolonged activity from Halemaʻumaʻu in the 1920s, the decades-long Puʻu ʻŌʻō eruption beginning in 1983, and the 2018 lower Puna eruption that caused widespread lava flows and seismicity. Eruptions have been characterized by effusive basaltic lava flows, explosive episodes at summit vents, and rift-fed fissure eruptions observed and analyzed by teams from the USGS Hawaiian Volcano Observatory, Pacific Tsunami Warning Center, and universities such as Stanford University and University of Alaska Fairbanks.

Monitoring and Research

Monitoring at Kilauea integrates seismic networks, ground deformation instruments, gas sensors, and remote sensing from satellites including Landsat, Sentinel-2, and geodetic missions like GPS arrays. The USGS Hawaiian Volcano Observatory operates seismic stations, tiltmeters, and InSAR campaigns in collaboration with the University of Hawaii HIGP, the Jet Propulsion Laboratory, and international partners such as European Space Agency. Research topics span magma dynamics, eruption forecasting, hazard modeling, and petrology, with contributors from labs at University of Oxford, Tokyo Institute of Technology, and National University of Singapore. Citizen science efforts and community partnerships involve the Mauna Kea Observatories network, local nongovernmental organizations, and cultural practitioners.

Hazards and Impact

Hazards from Kilauea include lava flows that have inundated towns in the Puna District, volcanic gas emissions such as sulfur dioxide creating vog episodes affecting Hilo and Honolulu, and explosive eruptions producing ash hazards akin to events studied at Mt. St. Helens and Eyjafjallajökull. Secondary impacts involve property loss, changes to coastal morphology at locations like Kalapana, and effects on infrastructure including Hawaiian Electric Industries service areas and Daniel K. Inouye International Airport air quality concerns. Emergency management coordination is conducted by agencies such as the Hawaii Department of Emergency Management, the Federal Emergency Management Agency, local county governments, and international humanitarian groups during major crises.

Cultural Significance and Human Interaction

Kilauea holds central importance in Native Hawaiian religion, myth, and land stewardship practices associated with deities like Pele and chiefs described in chants and mele collected by scholars at institutions such as the Bernice Pauahi Bishop Museum. Historically, Hawaiian communities engaged in agricultural practices near rift zones and adapted to periodic lava flows; these traditions intersect with modern land management by the Office of Hawaiian Affairs and cultural practitioners. Tourism driven by attractions in Hawaii Volcanoes National Park influences local economies, with operators, guides, and interpretive programs linked to organizations like the National Park Service, Hawaii Visitors and Convention Bureau, and museums such as the Volcano Art Center. Artistic responses appear in works by authors and artists connected to Mark Twain, Herbert Carter, and contemporary Hawaiian writers and musicians.
