K\u012blauea experienced a historically damaging eruption along its lower East Rift Zone in association with the volcano\u2019s largest summit collapse in over a century, which forced the Hawaiian Volcano Observatory to vacate its longtime post at U\u0113kahuna on the rim of Kaluapele (the summit caldera). These events were a significant disruption from the relatively steady-state activity exhibited for more than a decade prior, with low-effusion lava flows from Pu\u02bbu\u02bb\u014d\u02bb\u014d along the middle East Rift Zone in the latter stages of an eruption that began in 1983 and a summit lava lake that had first appeared in 2008. Eruptive activity since 2018 has been substantially more dynamic: following a year of quiescence in 2019, the summit of K\u012blauea experienced five eruptions lasting from a week to more than a year between 2020 and 2023, then the volcano had two relatively short eruptions along the Southwest Rift Zone (less than 1 day) and middle East Rift Zone (5 days) in 2024, followed by another summit eruption beginning December 23, 2024 that continues episodically at the time of this writing (February 2026). Meanwhile, neighboring Mauna Loa had a summit and upper Northeast Rift Zone eruption lasting two weeks from late November into December 2022, the volcano\u2019s first in thirty-eight years. This product contains geospatial data depicting features from each of these eruptions\u2014including lava flows\u2014and it will be updated with future effusive activity at the active subaerial volcanoes in the State of Hawaii: K\u012blauea, Mauna Loa, Hual\u0101lai, Mauna Kea, and Haleakal\u0101.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1TFQAGR", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.68c493f7d4be021a00d8cdea.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_68c493f7d4be021a00d8cdea", "keyword": ["Basalt", "East Rift Zone", "HI_post2018", "Haleakal\u0101", "Halema\u02bbuma\u02bbu", "Hawaii", "Holocene", "Hual\u0101lai", "Kaluapele", "K\u012blauea", "Lava flow", "Mafic volcanic rock", "Maui", "Mauna Kea", "Mauna Loa", "Moku\u02bb\u0101weoweo", "Northeast Rift Zone", "Pacific", "Pacific Islands", "Quaternary", "Southwest Rift Zone", "USGS:68c493f7d4be021a00d8cdea", "United States", "Volcanic rock", "volcanic activity", "volcanic rocks"], "modified": "2026-05-06T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-160.247083, 18.910685, -154.806690, 22.232460", "theme": ["geospatial"], "title": "Eruptions since 2018 in the State of Hawaii \u2014 vent points"}
