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 Puʻuʻōʻō, a cone with a central crater that was the vent region for Kīlauea’s 35-year middle East Rift Zone eruption starting in 1983. The rapid migration of magma from beneath Puʻuʻōʻō caused its crater floor to drop over 300 m. This data release includes a three-dimensional model of Puʻuʻōʻō and the collapse crater, constructed...
An intrusion into Kīlauea’s upper East Rift Zone during June 17–19, 2007, during the 1983–2018 Pu‘u‘ō‘ō eruption, led to widespread ground cracking and a small (~1,525 m3) eruption on the northeast flank of the Kānenuiohamo cone, about 6 km upslope from the Pu‘u‘ō‘ō vent. Transmitted and induced very-low-frequency (VLF) magnetic fields were measured with a handheld VLF receiver along transects spanning the dike trace, and zones of ground cracking related to the intrusion were mapped. This dataset records the density and vesicularity of selected lava and tephra samples collected from the June 2007 Father's Day eruption site. The density of the basalt erupted was determined by measuring the weight of spatter and lava...

Transmitted and induced very-low-frequency (VLF) magnetic fields were measured with a handheld VLF receiver along transects spanning the dike trace, and zones of ground cracking related to the intrusion were mapped. This dataset records the distance between sets of nails spanning ground cracks at discrete locations in Nāpau Crater, installed in 1997 as "crack stations" to monitor change. See fig. B-1 in the associated publication for a map of crack...

An intrusion into Kīlauea’s upper East Rift Zone during June 17–19, 2007, during the 1983–2018 Pu‘u‘ō‘ō eruption, led to widespread ground cracking and a small (~1,525 m3) eruption on the northeast flank of the Kānenuiohamo cone, about 6 km upslope from the Pu‘u‘ō‘ō vent. Electromagnetic profiles using the very-low-frequency (VLF) technique (McNeill and Labson, 1991) were measured along transects spanning the dike trace, and zones of ground cracking related to the intrusion were mapped. The locations of crack zones and the VLF receiver measurements suggest that the Father’s Day dike splayed as it approached the surface, dividing into four segments—one between Pauahi Crater and Pu‘uhuluhulu and three en echelon...

This dataset records measurements collected using a Geonics Limited EM16 very low frequency (VLF) electromagnetic receiver along eight transects across and perpendicular to the presumed trace of the 2007...

This dataset records the location, trend, width, and opening direction of a subset of new cracks formed during the June 2007 Father's Day dike intrusion and eruption.

Data collected by 11 borehole tiltmeters operated by the U.S. Geological Survey on Kīlauea Volcano, on the Island of Hawai'i. Data was collected between 30 April, 2018 and 5 August, 2018. Among the features captured by this data set are: the collapse of Puʻuʻōʻō on 30 April, 2018, the migration of magma down the East Rift Zone from 30 April to 3 May, 2018, the M6.9 earthquake on 4 May, 2018, and the deflation and collapse of the shallow magma chamber at Kīlauea from early May until 5 August, 2018. Data files for each station are zipped together into a single archive, which also includes a ReadMe.txt explanatory file. Zip archives are named with the three-letter station code that uniquely identifies the tiltmeter...
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 oblique aerial photographs using structure-from-motion (SfM) software shows that the volume of the flow (~68,000 m3) closely matches the volume of subsidence of the crusted lava lake (~64,000 m3). The similarity of these volumes, along with the textural characteristics of the lava, shows that the lava that fed the flow had been stored...
