Geospatial database of the 2018 lower East Rift Zone eruption of Kīlauea Volcano, Hawai‘i: contains data used to construct semi-daily lava-flow maps during the 2018 Kīlauea eruption. The data were sourced from helicopter and Unoccupied Aircraft Systems (UAS) imagery collected by both the USGS and the University of Hawai‘i at Hilo, as well as from various satellite sources. This report supersedes the "preliminary" web map service that was operated in 2018, and which remains on ScienceBase as a legacy dataset (accessible here). The primary component of this new report is a geodatabase prepared using ArcGIS, but Esri shapefiles and Google Earth KMZs are also included.

A summary chronology and interesting facts about Kīlauea Volcano's 2018 lower East Rift Zone eruption and summit collapse. See overview here...

The USGS has recently published aThis data release includes all 2019 campaign survey GPS sites on Kīlauea and Mauna Loa on the Island of Hawai‘i; it also includes semi-permanent stations in Kīlauea's Middle East Rift Zone that were occupied all year. GPS surveys are conducted annually by the Hawaiian Volcano Observatory to supplement permanent and semi-permanent GPS stations providing data on ground deformation . This data release includes data from a total of 69 sites that were occupied. All data (raw and rinex) are included along with metadata and log sheets.The USGS has recently published a. Kīlauea Volcano on the Island of Hawai‘i, has one of the longest running volcanic sulfur dioxide gas (SO emission rate records in the world. The volcano was in a state of nearly continuous eruption from 1983–2018, emitting large amounts of gas from the volcano's East Rift Zone (ERZ) during the entire eruptive period, and from the Overlook vent at the summit from 2008–2018. This data release presents our best estimates for ground-based SOemission rates from the two gas emission sources for the period 2008–2013. It provides revised data for previously published 2008–2010 emission rates and fills in the existing 2011–2013 data gap. Water was first observed at the summit of Kīlauea Volcano, within Hawai‘i Volcanoes National Park, one year ago. Since then, the body of water has. The Hawaiian Volcano Observatory continues to monitor the lake, and have. Additional resources are available on the Kīlauea summit water webpage . Kīlauea Volcano remains at alert-level NORMAL and aviation color-code GREEN. Levels of seismicity deformation , and gas emission remain at background levels.The USGS has recently published aThe surveys covered 219 square miles (567 sq km) and included Kīlauea Volcano's summit, lower East Rift Zone, and middle East Rift Zone (including the entire Pu‘u ‘Ō‘ō lava flow field active from 1983 through early 2018). This USGS data release contains a 1-meter resolution raster digital elevation model (DEM) of the ground surface, including beneath-forest cover ('bare earth'). The DEM can support a variety of earth science, civil engineering, and land-use investigations.HVO has updated the Geology & History webpages for Kīlauea and Mauna Loa volcanoes. These pages now include maps and links to revised tables summarizing volcanic activity over the past ~200 years at each volcano.
