Thermal maps of the 2018 lower East Rift Zone eruption of Kīlauea Volcano, Island of Hawaiʻi Thermal maps of the 2018 lower East Rift Zone eruption of Kīlauea Volcano, Island of Hawaiʻi
The 2018 eruption of Kīlauea Volcano included both a large effusive eruption on the lower East Rift Zone and associated collapse and subsidence of the caldera floor at the summit (Anderson and others 2019; Neal and others 2019; Patrick and others 2020). Lava erupted from 24 fissures on the lower East Rift Zone over four months, with high effusion rates (>100 m3 s-1) often supplying lava...
Photogrammetry-derived digital elevation models and source images for an inactive perched lava lake formed at Pu‘u‘ō‘ō (Kīlauea) in 2014 Photogrammetry-derived digital elevation models and source images for an inactive perched lava lake formed at Pu‘u‘ō‘ō (Kīlauea) in 2014
Lava flow hazards are usually thought to end when the erupting vent becomes inactive, but this is not always the case. At Kīlauea in August 2014, a spiny ʻaʻā flow erupted from the levee of a crusted perched lava lake that had been inactive for a month, and the surface of the lava lake subsided as the flow advanced downslope over the following few days. Topography constructed from...
Thermal camera data for the summit of Kīlauea Volcano, 2019–2022 Thermal camera data for the summit of Kīlauea Volcano, 2019–2022
Following the 2018 collapses of the caldera floor at the summit of Kīlauea Volcano (Anderson and others, 2019; Neal and others, 2019), the enlarged and deepened depression hosted a variety of volcanic activity between 2019 and 2022. These events included an unprecedented water lake and two prolonged episodes of lava lake activity. This data release includes images from a stationary...

This data release includes measurements of the surface elevation of the lava lake within Halemaʻumaʻu crater, at the summit of Kīlauea Volcano, during the 2008-2018 summit eruption (Patrick and others, 2021). The data were measured by several instruments (laser rangefinder, webcams, lidar) and are compiled here to provide the most complete dataset yet available on the elevation of...
Colorimeter data for the summit water lake at Kīlauea Volcano, Island of Hawaiʻi, 2020 Colorimeter data for the summit water lake at Kīlauea Volcano, Island of Hawaiʻi, 2020
In 2018, a large effusive eruption on the lower flank of Kīlauea Volcano was associated with collapse and subsidence of the summit caldera floor (Neal and others, 2019). The bottom of Halemaʻumaʻu, a crater nested within the summit caldera, subsided by more than 500 m. In July 2019, water was observed ponding on the deepest part of the Halemaʻumaʻu crater floor and the water rose and...
Sample details and near-real-time ED-XRF, grain size, and grain shape data collected during the November – December 2022 eruption of Mauna Loa volcano, Island of Hawaiʻi Sample details and near-real-time ED-XRF, grain size, and grain shape data collected during the November – December 2022 eruption of Mauna Loa volcano, Island of Hawaiʻi
At 11:21 p.m. (Hawaii Standard Time [HST]) on November 27, 2022, Mauna Loa volcano on the Island of Hawaiʻi started erupting from fissures at its summit caldera, Mokuʻāweoweo. This was followed shortly afterwards by the opening of a segment of fissures in the direction of the Southwest Rift Zone. These were mostly within the structural boundary of the caldera, so their location is...

Toward next-generation lava flow forecasting: Development of a fast, physics-based lava propagation model Toward next-generation lava flow forecasting: Development of a fast, physics-based lava propagation model
During effusive volcanic crises, the eruption and propagation of lava flows pose a significant hazard to nearby populations, homes, and infrastructure. Consequently, timely lava flow forecasts are a critical need for volcano observatory and emergency management operations. Previous lava flow modeling tools are typically either too slow to produce timely forecasts, or are fast, but lack...

Development, structure, and behavior of a perched lava channel at Kīlauea Volcano, Hawaiʻi, during 2007 Development, structure, and behavior of a perched lava channel at Kīlauea Volcano, Hawaiʻi, during 2007
Channelized lava flows are commonly produced during the early stages of basaltic eruptions. These channels usually maintain their morphology until the eruption ends or discharge is diverted. In some instances, narrower channels can roof over, developing into lava tubes. We report here on a channelized flow erupted at Kīlauea volcano in 2007 that evolved into a “perched lava channel”...

Damage assessment for the 2018 lower East Rift Zone lava flows of Kīlauea volcano, Hawaiʻi Damage assessment for the 2018 lower East Rift Zone lava flows of Kīlauea volcano, Hawaiʻi
Cataloguing damage and its correlation with hazard intensity is one of the key components needed to robustly assess future risk and plan for mitigation as it provides important empirical data. Damage assessments following volcanic eruptions have been conducted for buildings and other structures following hazards such as tephra fall, pyroclastic density currents, and lahars. However...

Rainfall an unlikely trigger of Kilauea’s 2018 rift eruption Rainfall an unlikely trigger of Kilauea’s 2018 rift eruption
If volcanic eruptions could be forecast from the occurrence of some external process, it might be possible to better mitigate risk and protect lives and livelihoods. Farquharson and Amelung1 suggested that the 2018 lower East Rift Zone (ERZ) eruption of Kīlauea Volcano—the most destructive eruption in Hawai‘i in at least 200 years2—was triggered by extreme precipitation, which caused...

Crater growth and lava-lake dynamics revealed through multitemporal terrestrial lidar scanning at Kīlauea Volcano, Hawaiʻi Crater growth and lava-lake dynamics revealed through multitemporal terrestrial lidar scanning at Kīlauea Volcano, Hawaiʻi
Lava lake surfaces display the tops of active magma columns and respond to eruption variables such as magmatic pressure, convection, degassing, and cooling, as well as interactions with the craters that contain them. However, they are challenging to study owing to the numerous hazards that accompany these eruptions, and they are typically difficult to observe because the emitted gas...

Evaluating lava flow propagation models with a case study from the 2018 eruption of Kīlauea Volcano, Hawai'i Evaluating lava flow propagation models with a case study from the 2018 eruption of Kīlauea Volcano, Hawai'i
The 2018 lower East Rift Zone (LERZ) eruption of Kīlauea, Hawai’i, provides an excellent natural laboratory with which to test models of lava flow propagation. During early stages of eruption crises, the most useful lava flow propagation equations utilize readily determined parameters and require fewer a priori assumptions about future behavior of the flow. Here, we leverage the numerous
