Nāhuku (Thurston Lava Tube) is a prominent lava tube located within Hawaii Volcanoes National Park on Hawaii Island, formed by historic eruptions of Mauna Loa and Kīlauea. The site is frequently visited by tourists from National Park Service facilities, researchers from institutions such as the Smithsonian Institution and University of Hawaiʻi, and educators associated with National Geographic and American Geophysical Union programs.
Nāhuku is a well-preserved lava tube accessible from the Chain of Craters Road area inside Hawaii Volcanoes National Park, lying within the broader landscape shaped by Kīlauea activity and flows attributed to Puʻu ʻŌʻō and Mokuʻāweoweo (summit). The site is interpreted by staff from the National Park Service and geologists from the United States Geological Survey who study volcanology, lava morphologies, and Pacific Islands volcanic systems.
The tube formed in pāhoehoe flows related to Kīlauea and possibly Mauna Loa eruptive phases; lava that built the tube displayed sheathed flow margins comparable to features described in studies by the USGS Hawaiian Volcano Observatory. Researchers from the American Geophysical Union and Geological Society of America compare Nāhuku's dimensions and skylight entrances to other lava tubes documented near Ala Kahakai National Historic Trail and in the Galápagos Islands and Icelandic Volcanism analogs. Fieldwork by teams from the University of Hawaiʻi at Mānoa, California Institute of Technology, and Massachusetts Institute of Technology has applied radiometric constraints and petrographic analyses similar to protocols used in Tephrochronology research to refine emplacement timing and cooling histories.
Nāhuku occupies a place in Native Hawaiian oral histories and chants collected by scholars affiliated with Bishop Museum and University of Hawaiʻi archives; cultural practitioners associated with the Office of Hawaiian Affairs and kūpuna (elders) provide guidance on protocols for access. The tube's English name derives from Lorrin A. Thurston and historical accounts tied to early twentieth-century Hawaiian territorial administration and tourism development influenced by figures linked to Territory of Hawaii history. Interpretive programming at the site coordinates with curators from the Hawaiʻi State Archives, educators from Bishop Museum, and cultural officers from Hawaii Volcanoes National Park to balance scientific interpretation with traditional practices.
The microenvironment inside Nāhuku supports troglofaunal and macroinvertebrate assemblages documented in cave biology studies conducted by researchers from Hawaii Biological Survey and universities including University of California, Berkeley and University of Hawaiʻi. Endemic arthropods and specialized fungi have been sampled using methods consistent with protocols from the Society for Conservation Biology and comparative analyses referencing cave ecosystems in New Zealand and Australia. Park biologists working with USGS and National Park Service vetting identify sensitive species and monitor impacts related to introduced predators associated with nearby developments on Hawaii County lands.
Access to Nāhuku is managed via trails maintained by National Park Service crews and is served by interpretive signage developed in collaboration with Hawaii Volcanoes National Park rangers, staff from National Park Foundation, and volunteers from Friends of Hawaii Volcanoes National Park. Visitor infrastructure includes boardwalks, lighting installed per conservation guidelines from National Park Service and professional standards used by the International Union for Conservation of Nature for protected area interpretation. Guided programming and safety briefings are offered by park interpreters and licensed guides connected to Hawaii Visitors and Convention Bureau and educational partnerships with Kīpuka Kī Community Learning Center and university extension programs.
Management of Nāhuku is governed by Hawaii Volcanoes National Park policy under the United States National Park Service framework, with scientific input from the USGS Hawaiian Volcano Observatory, legal guidance from United States Department of the Interior, and cultural consultation with Office of Hawaiian Affairs and Native Hawaiian kūpuna. Conservation measures address visitor impact, biosecurity to prevent introduction of nonnative species as framed by Convention on Biological Diversity principles, and monitoring protocols aligned with standards from the International Union for Conservation of Nature and the National Park Service Inventory and Monitoring Program. Collaborative research agreements with institutions such as University of Hawaiʻi, Smithsonian Institution, and Bishop Museum support long-term studies and adaptive management to protect geological integrity and cultural values.
