New USGS geonarrative describes Kīlauea Volcano's 2018 events September 19, 2019 In 2018, Kīlauea experienced its largest lower East Rift Zone eruption and summit collapse in at least 200 years. This new USGS geonarrative provides a brief overview of recent Kīlauea eruptions, highlighting the circumstances leading up to and summarizing the 2018 events. It can be viewed on any device, but on a smart phone, it is best displayed in landscape mode. See the geonarrative here.

New USGS data release has GIS shapefiles for the June 27th lava flow May 22, 2019
This GIS dataset shows the evolution of the "June 27th" lava flow (episode 61e of the Pu‘u ‘Ō‘ō eruption) that was active from June 27, 2014, to June 8, 2016, and threatened the town of Pāhoa, on the Island of Hawai‘i. The dataset also includes the eruptive fissures, the principle ground cracks that were occupied by lava during emplacement of the June 27th flow, and the lava tube system that developed. Follow the link to download GIS shapefiles for the June 27th lava flow at Kīlauea volcano, Hawai‘i, June 2014–June 2016.
