The 1983-2018 Puʻuʻōʻō eruption, on the East Rift Zone of Kīlauea volcano, consisted of many different episodes and several phases of lava flows threatening residential areas (Heliker and Mattox 2003; Orr and others 2015). One of these crises occurred in 2014-2015, when lava erupting from Puʻuʻōʻō advanced north of the rift zone, towards the town of Pāhoa (Poland and others 2016; Brantley and others 2019). This slow-moving crisis unfolded over approximately four months, as pāhoehoe lava gradually flowed towards the town. In the end, the lava flow fortunately stalled at the edge of the residential area, destroying only one home. During the crisis, geologists at the U.S. Geological Survey (USGS) Hawaiian Volcano...

During 2018, Kīlauea Volcano, on the Island of Hawaiʻi, had a large effusive eruption (~1 cubic kilometer of lava) on the lower East Rift Zone that caused widespread destruction (Neal and others, 2019; Dietterich and others, 2021). This lower flank eruption was accompanied by one of the largest collapses of the summit caldera in two hundred years, with portions of the caldera floor subsiding more than 500 m (Anderson and others, 2019; Neal and others, 2019). On July 25, 2019, approximately one year after the summit collapse sequence, a small pond of water was first observed in the deepest portion of the collapse pit, within Halemaʻumaʻu crater (Nadeau and others, 2020). The water level rose gradually over the...

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...

The 2022 eruption of Mauna Loa volcano, Island of Hawaiʻi, was the first eruption on the volcano since 1984, producing a 17 km lava flow that threatened a major highway (Mulliken and others 2024; Zoeller and others 2024). The eruption began with lava fountaining in the summit caldera (Mokuʻāweoweo) at 23:21 HST on November 27, transitioning to vents on the Northeast Rift Zone (NERZ) by the next morning. The dominant vent on the NERZ—fissure 3—was active for about 13 days, sending a lava flow to the north that stalled within 3 km of Daniel K. Inouye Highway. The eruption ended on December 10, having covered a section of the Mauna Loa Observatory Road but otherwise causing no major damage. During the eruption,...
