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...

Alamagan Volcano is a Quaternary stratovolcano along the Mariana Arc, an active subduction zone in the western Pacific Ocean. Although primarily submerged, its peak reaches above sea level, with subaerially-exposed volcanic deposits dating back through the Holocene to the late Pleistocene. These feature data represent such deposits and other geologic features of Alamagan Volcano, describing its interpreted eruptive history.

We depict changing eruptive features within the summit caldera of Kīlauea volcano, Island of Hawaiʻi with rapid-response digital elevation models (DEMs) acquired since a series of caldera-filling effusive eruptions began on December 20, 2020. These eruptions follow the caldera collapse of 2018, with new lava progressively filling the approximately 1-cubic-kilometer pit that formed between May and August of that year. The majority of the provided DEMs were constructed via structure-from-motion (SfM) photogrammetry from either helicopter or uncrewed aircraft system (UAS) overflight images, with the remainder constructed via terrestrial laser scanning (TLS) from the Halemaʻumaʻu crater rim. These data were collected...

This dataset contains shapefiles and associated metadata for Kīlauea volcano's Pu‘u ‘Ō‘ō episode 61g lava flow from May 24, 2016 through May 31, 2017. Episode 61g began with a breakout from the east flank of Pu‘u ‘Ō‘ō on May 24, 2016. Lava reached the Pacific Ocean at Kamokuna on July 26, 2017, and began building a lava delta that extended seaward from the original coastline. This lava delta collapsed into the ocean on December 31, 2016, as reflected in the data for January 12, 2017 and thereafter. The episode 61g lava flow continues as of May 31, 2017, the date of the last mapping to contribute to this dataset. One mapping date is included for each calendar month - usually late in the month - from May 2016 through...
