Crater geometry data for Puʻuʻōʻō, on Kīlauea Volcano’s East Rift Zone, in May 2018 Crater geometry data for Puʻuʻōʻō, on Kīlauea Volcano’s East Rift Zone, in May 2018
The 2018 lower East Rift Zone eruption and accompanying summit collapse of Kīlauea Volcano, Hawaiʻi, comprised one of the most impactful events on the volcano in the past 200 years, with hundreds of homes destroyed and major changes in the topography of the summit caldera. The opening stages of this eruptive sequence started on 30 April, when a magmatic dike began moving east from...
Volcanic plume heights from the summit of Kilauea Volcano, Hawai'i Volcanic plume heights from the summit of Kilauea Volcano, Hawai'i
This data release provides volcanic plume heights from the summit of Kilauea Volcano for 2008-2015, and during the eruptive events of 2018. For 2018, a Secacam Wild Vision Full HD camera with a 7mm focal length was located at 1717 m elevation approximately 15 m south of the Mauna Loa Strip Road within Hawai'i Volcanoes National Park, 19.475843degreesN, 155.363560degreesW (WGS84). The...
Lava level and crater geometry data during the 2018 lava lake draining at Kilauea Volcano, Hawaii Lava level and crater geometry data during the 2018 lava lake draining at Kilauea Volcano, Hawaii
In May 2018, the onset of new eruptive activity on the lower flank of Kīlauea Volcano, Hawaiʻi, accompanied the draining of the lava lake at the summit, 40 km upslope. The lava lake draining lasted over seven days, and transitioned into the largest collapse event at the summit of Kīlauea in over 200 years, with the paired flank and summit activity marking a historic episode in the modern...
Cyclic lava effusion during the 2018 eruption of Kilauea Volcano: data release Cyclic lava effusion during the 2018 eruption of Kilauea Volcano: data release
This USGS data release includes data related to the Science magazine manuscript "Cyclic lava effusion during the 2018 eruption of Kilauea Volcano" by Patrick et al. The data release includes 1) original video as well as thermal, and timelapse images of lava in the proximal Fissure 8 channel, 2) derived estimates of lava level in the channel and bulk effusion rates (not corrected for...

This dataset contains shapefiles and associated metadata showing evolution of the "June 27th" lava flow (Pu?u ???? eruptive episode 61e) that was active at Kilauea volcano from June 27, 2014, to June 8, 2016. The dataset contains (1) an attributed polyline shapefile and (2) an attributed polygon shapefile with features that represent the outline and extent of the flow on 35 different...

This dataset contains shapefiles and associated metadata for Kīlauea volcano's Puu Ōō episode 61g lava flow from May 24, 2016 through May 31, 2017. Episode 61g began with a breakout from the east flank of Puu Ōō on May 24, 2016. Lava reached the Pacific Ocean at Kamokuna on July 26, 2017, and began building a lava delta that extended seaward from the original coastline. This lava delta...

High-speed lava flow infrasound from Kīlauea’s fissure 8 and its utility in monitoring effusion rate High-speed lava flow infrasound from Kīlauea’s fissure 8 and its utility in monitoring effusion rate
The 2018 eruption of Kīlauea Volcano produced large and destructive lava flows from the fissure 8 (Ahu ‘aila ‘au) vent with flow velocities up to 17 m s−1, highly variable effusion rates over both short (minutes) and long (hours) time scales, and a proximal channel or spillway that displayed flow features similar to open channel flow in river systems. Monitoring such dynamic vent and...

Onset and evolution of Kilauea’s 2018 flank eruption and summit collapse from continuous gravity Onset and evolution of Kilauea’s 2018 flank eruption and summit collapse from continuous gravity
Prior to the 2018 lower East Rift Zone (ERZ) eruption and summit collapse of Kīlauea Volcano, Hawai‘i, continuous gravimeters operated on the vent rims of ongoing eruptions at both the summit and Pu‘u ‘Ō‘ō. These instruments captured the onset of the 2018 lower ERZ eruption and the effects of lava withdrawal from both locales, providing constraints on the timing and style of activity and...

Brittle fragmentation by rapid gas separation in a Hawaiian fountain Brittle fragmentation by rapid gas separation in a Hawaiian fountain
Brittle fragmentation, generating small pyroclasts from magma, is a key process determining eruptive style. How low-viscosity magma fragments within a rising fountain in a brittle manner, however, is not well understood. Here we describe a fragmentation process in Hawaiian fountains on the basis of observations from the 2018 lower East Rift Zone eruption of Kīlauea Volcano, Hawai’i. The...

Lava effusion rate evolution and erupted volume during the 2018 Kīlauea lower East Rift Zone eruption Lava effusion rate evolution and erupted volume during the 2018 Kīlauea lower East Rift Zone eruption
The 2018 eruption on the lower East Rift Zone of Kīlauea Volcano produced one of the largest and most destructive lava flows in Hawai’i during the past 200 years. Over the course of more than 3 months, twenty-four fissures erupted, and the rate of lava effusion varied by two orders of magnitude, with significant implications for evolving flow behavior and hazards. Syn-eruptive data were...

Patterns of bubble bursting and weak explosive activity in an active lava lake—Halema‘uma‘u, Kīlauea, 2015 Patterns of bubble bursting and weak explosive activity in an active lava lake—Halema‘uma‘u, Kīlauea, 2015
The rise of the Halemaʻumaʻu lava lake in 2013–2018 to depths commonly 40 meters or less below the rim of the vent was an excellent opportunity to study outgassing and the link to associated eruptive activity. We use videography to investigate the rise and bursting of bubbles through the free surface of the lake in 2015. We focus on low-energy explosive activity (spattering) in which the...

Groundwater dynamics at Kīlauea Volcano and vicinity, Hawaiʻi Groundwater dynamics at Kīlauea Volcano and vicinity, Hawaiʻi
Kīlauea Volcano, on the Island of Hawaiʻi, is surrounded and permeated by active groundwater systems that interact dynamically with the volcanic system. A generalized conceptual model of Hawaiian hydrogeology includes high-level dike-impounded groundwater, very permeable perched and basal aquifers, and a transition (mixing) zone between freshwater and saltwater. Most high-level...
