Stochastic lava flow forecasting code used during the 2014-2015 Pāhoa lava flow crisis, Kīlauea Volcano, Island of Hawai‘i

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...

Digital elevation models and orthoimagery from the 2018 eruption of Veniaminof, Alaska

Aerial photography surveys during and after the 2018 eruption of Veniaminof Volcano, Alaska were conducted to track the evolution of the lava flow field, active volcanic vent, and glacial ice loss from the eruption. Imagery from two surveys was processed with structure-from-motion (SfM) photogrammetric methods to derive the digital elevation models (DEMs) and orthophotos in this data release. The datasets cover the active volcanic cone and intracaldera ice cap, which both show significant topographic and groundcover change between surveys, and relative to previous topographic reference data, due to the 2018 eruption and variable snow and ice cover. A syn-eruption survey on September 26, 2018 was conducted by the...

Appendix C - Density and vesicularity data for selected lava and tephra samples from the June 2007 Father's Day eruption site, Kīlauea Volcano

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...

GIS shapefiles for Kīlauea's episode 61g lava flow, Pu‘u ‘Ō‘ō eruption: May 2016 to May 2017

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...

GIS shapefiles for the June 27th lava flow at Kīlauea volcano, Hawaiʻi, June 2014–June 2016

This dataset contains shapefiles and associated metadata showing evolution of the "June 27th" lava flow (Puʻu ʻŌʻō eruptive episode 61e) that was active at Kīlauea volcano from June 27, 2014, to June 8, 2016. The dataset contains (1) an attributed polyline shapefile and (2) an attributed polygon shapefile with features that represent the outline and extent of the flow on 35 different dates. The dataset also contains (3) an attributed polyline shapefile with features that represent the eruptive fissures associated with this episode of the eruption and the principle ground cracks that were occupied by lava during lava flow emplacement, and (4) an attributed polyline shapefile with features representing the mapped...
