Chemical and isotopic composition of gas, water, and solids from the 2019-2020 water lake in Halema’uma’u Crater, Kīlauea Volcano, Hawaii
Following the 2018 eruption of Kīlauea Volcano (Neal et al, 2019) and the subsequent collapse of the Halema’uma’u crater, groundwater gradually seeped into the newly-deepened crater (Nadeau and others, 2020). Water was first observed in the crater on 7/26/2019, and the water level increased over time until 12/20/2020, when the crater again filled with lava, vaporizing the lake. In the intervening
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 record of
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 groundwater is asso

The 2018 rift eruption and summit collapse of Kilauea Volcano
In 2018, Kīlauea Volcano experienced its largest lower East Rift Zone (LERZ) eruption and caldera collapse in at least 200 years. After collapse of the Pu'u 'Ō'ō vent on 30 April, magma propagated downrift. Eruptive fissures opened in the LERZ on 3 May, eventually extending ~6.8 km. A 4 May earthquake (M6.9) produced ~5 m of fault slip. Lava erupted at rates exceeding 100 m3/s, eventually coveri
