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...

La Soufrière Volcano is a 1,220 m high stratovolcano that occupies the northern half of the island of St. Vincent, Lesser Antilles, Eastern Caribbean. It has a long history of explosive and sometimes devastating eruptions. Beginning in December 2020 and ending in April 2021, La Soufrière Volcano produced a Volcano Explosivity Index (VEI) 4 eruption that greatly impacted the landscape, communities, and infrastructure on the island of St. Vincent. The eruption produced intense ash plumes, heavy ashfall, and pyroclastic flows down several river valleys. During and following the eruption, destructive lahars (volcanic mudflows) impacted rivers valleys and coastal communities for months. The USGS-USAID Volcano Disaster...
The youngest and largest island in the State of Hawaii—the Island of Hawai‘i—is formed by five volcanoes, three of which have erupted within recent geologic history: Mauna Loa, Kīlauea, and Hualālai. This data release provides a chronology for activity and impacts at Mauna Loa, Kīlauea, and Hualālai over approximately the past two and a half centuries. This data release includes a word document, “HI_volcanoes_chronology_description,” that describes the data compilation process and provides simple summary tables of eruptive activity and maps. A CSV file contains the compiled eruption chronology data for all volcanoes—"HI_volcanoes_chronology_data”—references for which are provided in a separate CSV file titled “HI_volcanoes_chronology_references.”...

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 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.
