Digital database of the geologic map of the middle east rift geothermal subzone, Kīlauea Volcano, Hawai‘i

A comprehensive digital database of the geologic map of the middle East Rift Zone (MERZ) geothermal subzone, Kīlauea Volcano, Hawai‘i, reveals the distribution and characteristics of 34 late Holocene eruptions over approximately 27 square kilometers. The study provides a detailed framework for understanding lava flow patterns, vent locations, and their relationship to topographic features, with lava flows typically directed northeast or southeast based on vent positioning relative to the rift zone's crest. The database, prepared using ArcGIS and Esri shapefiles, integrates radiocarbon dating, stratigraphic relations, weathering observations, soil development, and vegetative cover to assign numerical ages to rock groups. This resource supports further research into the volcanic processes and geothermal activity of Kīlauea while also offering insights into the tropical rainforest ecosystem's interaction with volcanic terrain.
