GIS shapefiles for lava flows at Kilauea volcano, 1790–1982 (ver. 1.1, October 2024)

This dataset contains shapefiles and associated metadata for lava flows erupted at Kilauea volcano from ca. 1790 through 1982. The dataset includes all known subaerial eruptions in the volcano's Southwest Rift Zone and East Rift Zone, and selected flows erupted within the summit caldera, during this time period. Two attributed shapefiles are associated with each eruption: a polyline shapefile for the lava flow contacts and eruptive fissures, and a polygon shapefile showing the full extent of the lava flow after emplacement. In total, this dataset contains 100 shapefiles, each with an associated metadata .txt file, representing 50 separate eruptions. The lava flow contacts and fissures were mapped on the ground using a handheld GPS, were digitized from satellite imagery, or were digitized from scanned and georegistered maps and aerial photographs; the relevant sources for each feature are assigned in the attribute table.
