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...

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

This release includes data collected during campaign GPS surveys at Kīlauea and Mauna Loa Volcanoes on the Island of Hawaiʻi in 2021. It includes data from a total of 63 sites occupied from January 1 to December 31, 2021. For each site, we include its measured raw data in daily files, Receiver INdependent EXchange (RINEX) files for each day, field log sheet(s), and associated metadata information. We also include a few days of data at the end of 2020 at 3 longer-term campaign sites at Kīlauea’s summit. These sites (109Y, NDDB, OVRL) were deployed in late December 2020 in response to the December 20, 2020, Kīlauea summit eruption. The authors thank USGS Hawaiian Volcano Observatory staff, volunteers, and collaborators...

This dataset includes sample information, vesicularity by pycnometer, grain size and shape data by CAMSIZER, and measurements of crushed and thin section mounted grains by microscope. All studied samples were from scoria and air-fall-tephra deposits (most formed in Hawaiian lava fountains) collected around the summits of Mauna Loa and Kīlauea volcanoes, Island of Hawaiʻi. These data were used to derive methods for quickly being able to quantify vesicularity in near-real-time during an eruption response. The samples from Kīlauea all erupted from the summit area and include Keanakākoʻi units B, D, E, K1, and K2, the Halemaʻumaʻu eruptions in September 2021 and September 2023, and the Kīlauea Iki eruption that formed...
