Fundamental Science Practices
USGS provides unbiased, objective, and impartial scientific information upon which our audiences, including resource managers, planners, and other entities, rely.
USGS provides unbiased, objective, and impartial scientific information upon which our audiences, including resource managers, planners, and other entities, rely.
Our programs produce accurate geologic maps and 3-D geologic frameworks that provide critical data for sustaining and improving the quality of life and economic vitality of the Nation. They also organize, maintain, and publish the geospatial baseline of the Nation's topography, natural landscape, built environment and more.

October 7, 2026—InSAR image showing Kīlauea summit deformation and earthquakes between September 24–October 2, 2026 October 7, 2026—InSAR image showing Kīlauea summit deformation and earthquakes between September 24–October 2, 2026
COSMO-SkyMed Second Generation (CSG) interferogram showing deformation of the ground surface around the summit of Kīlauea volcano from September 24 to October 2, 2026.
October 1, 2026—InSAR image of Kīlauea deformation between September 11–27 and earthquakes September 30–October 1 October 1, 2026—InSAR image of Kīlauea deformation between September 11–27 and earthquakes September 30–October 1
COSMO-SkyMed Second Generation interferogram for the period from September 11–27, 2026, covering Kīlauea volcano’s summit region. The symbol in the upper left indicates the satellite's orbit direction (arrow) and look direction (bar).
September 23, 2026—New Kīlauea summit vents and lava flows, September 14–16 September 23, 2026—New Kīlauea summit vents and lava flows, September 14–16
This reference map depicts new vents and lava flows that erupted within Halema‘uma‘u crater at the summit of Kīlauea from September 14–16, 2026.
September 16, 2026 — Thermal map showing recent lava flows in Halemaʻumaʻu, Kīlauea summit September 16, 2026 — Thermal map showing recent lava flows in Halemaʻumaʻu, Kīlauea summit
This thermal map of the summit of Kīlauea was constructed from images collected during a morning overflight on September 16, 2026. The map shows two small but active flows in the northwest portion of Halema‘uma‘u crater, erupting from new vents that opened in the past two days.
September 16, 2026—Kīlauea summit eruption reference map September 16, 2026—Kīlauea summit eruption reference map
This reference map depicts new eruptive vents and lava flows in Halema‘uma‘u crater at the summit of Kīlauea since September 14, 2026.
September 8, 2026—Kīlauea summit eruption reference map September 8, 2026—Kīlauea summit eruption reference map
This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u crater that began on December 23, 2024. Most of the data for this map were collected during a USGS Hawaiian Volcano Observatory helicopter overflight on August 28, 2026, so the provided statistics are reflective of the entire eruption through episode 54 on August 25.
September 3, 2026—Kīlauea summit eruption tephra thickness through episode 52 September 3, 2026—Kīlauea summit eruption tephra thickness through episode 52
This map depicts cumulative tephra thicknesses for the Kīlauea summit eruption in areas southwest of the Halema‘uma‘u eruptive vents as of July 29, 2026.
Altitude of the potentiometric surface and depth to water in the Mississippi River Valley alluvial aquifer, spring 2024 Altitude of the potentiometric surface and depth to water in the Mississippi River Valley alluvial aquifer, spring 2024
Potentiometric-surface and depth-to-water maps for spring 2024 were created for the Mississippi River Valley alluvial aquifer using groundwater-altitude data from 1,151 wells completed in the Mississippi River Valley alluvial aquifer and from the altitude of the top of the water surface in area rivers from 160 U.S. Geological Survey and U.S. Army Corps of Engineers streamgages.
