HVO monitors the active volcanoes in Hawaii, assesses their hazards, issues warnings, and advances scientific
understanding to reduce impacts of volcanic eruptions.
New USGS Data Release - Digital elevation model of Kīlauea Volcano, Hawai‘i, based on July 2019 airborne lidar surveys
July 09, 2020
The USGS has recently published a "Digital elevation model of Kīlauea Volcano, Hawai‘i, based on July 2019 airborne lidar surveys."
The 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.
Magnitude-4.3 and 4.6 earthquakes on Kīlauea Volcano's south flank
July 03, 2020
HVO recorded a magnitude-4.3 earthquake
located beneath Kīlauea Volcano's south flank on Friday, July 3, at 2:19 p.m., HST and a magnitude-4.6 earthquake located beneath Kīlauea Volcano's south flank on Thursday, July 2, at 11:20 p.m., HST. The earthquakes
were centered several km (miles) south of Pu‘u ‘Ō‘ō, at several km (miles) depth. The location, depth, and waveforms recorded for these earthquakes are consistent with slip along Kīlauea's south flank fault. Neither earthquake had an apparent effect on Kīlauea or Mauna Loa volcanoes. Read the full press releases here
Updates to HVO's Kīlauea and Mauna Loa "Geology & History" Webpages
June 08, 2020
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. You can also access the updated maps and tables directly at the links below.

New resource on health hazards of volcanic and geothermal gases
June 08, 2020
The International Volcanic Health Hazard Network (IVHHN) in cooperation with USGS, has released "The Health Hazards of Volcanic and Geothermal Gases: a Guide for the Public." The 20-page booklet addresses health hazards and impacts of volcanic and geothermal gases and aerosols. It also documents protective actions to take when visiting or living in these environments. Information was reviewed by health and science professionals from 6 countries and is applicable to volcanic and geothermal environments. The booklet is 4th in a series of IVHN products providing hazard information to the public and emergency managers. The document is available for download here.
New USGS Data Release - Geospatial database of the 2018 lower East Rift Zone eruption of Kīlauea Volcano, Hawai‘i
May 26, 2020
The recently published "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.
New publication - Geologic Map of the Southern Flank of Mauna Loa Volcano, Island of Hawai‘i, Hawaii
April 28, 2020
From east to west, this map covers the area from Punalu‘u to Miloli‘i and, from north to south, extends from north of Pu‘u‘oke‘oke‘o to Kalae (South Point). The map encompasses 1,163 square kilometers of the southwest flank of Mauna Loa, from 7,325 ft elevation to sea level. It shows the distribution of eruptive units (flows), which are separated into 16 age groups, ranging from more than 100,000 years before present to A.D. 1950. The Geologic Map of the Southern Flank of Mauna Loa Volcano, Island of Hawai‘i, Hawaii can be viewed here. This map is part three in a series which also includes the Geologic Map of the Central-Southeast Flank of Mauna Loa Volcano, Island of Hawai‘i, Hawaii and the Geologic Map of the Northeast Flank of Mauna Loa Volcano, Island of Hawai‘i, Hawaii.
Update on HVO operations during COVID-19 and Hawaii's Shelter-in-Place Order
March 25, 2020
The USGS Hawaiian Volcano Observatory (HVO) continues to monitor Hawaiian volcanoes and earthquakes and issue regular updates of volcanic activity. Through telework and other adaptations, HVO will maintain monitoring networks and continue analysis of incoming data. Field crews will visit critical stations as needed to maintain required quality and functionality of the network. All work will follow federal government guidelines to ensure public safety and the safety of our staff. The health and safety of our communities and our employees are our highest priorities, and we continue to follow guidance from the White House, the Centers for Disease Control and Prevention (CDC), and State and local authorities as we implement teleworking, social distancing and virtual meeting tools. Please follow our work at our website: https://volcanoes.usgs.gov/observatories/hvo/
USGS releases 2018 eruption datasets
March 02, 2020
These data releases relate to three papers about Kīlauea Volcano's 2018 eruption published in the December 2019 issue of Science (Vol 366, Issue 6470):
Cyclic lava effusion during the 2018 eruption of Kīlauea Volcano: data release: Includes video and thermal and timelapse images of the fissure 8 lava channel, derived estimates of lava level in the channel and bulk effusion rates, infrasound data, and other data.
Lava level and crater geometry data during the 2018 lava lake draining at Kīlauea Volcano, Hawai‘i: Includes two datasets that characterize draining of the Kīlauea summit lava lake in 2018: elevation data of the lava lake surface and three-dimensional models of the drained crater.
Whole-rock and glass chemistry of lava samples collected during the 2018 Lower East Rift Zone eruption of Kīlauea: Selected results from analyses of 2018 lava samples, including sampling-site information, eruptive vent/fissure, and sampling descriptions.
