Maps

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.

May 8, 2026 — Kīlauea lava flow and tephra fall map following episodes 45 and 46 May 8, 2026 — Kīlauea lava flow and tephra fall map following episodes 45 and 46

This map shows lava flow and tephra accumulation at the summit of Kīlauea volcano associated with episode 45 and 46 of the ongoing eruption in Halemaʻumaʻu that started on December 23, 2024, using data recorded by the Italian Space Agency's (ASI) COSMO-SkyMed Second Generation satellite constellation.

April 23, 2026 — Thermal map of episode 45 lava flows at the summit of Kīlauea April 23, 2026 — Thermal map of episode 45 lava flows at the summit of Kīlauea

This thermal map was made from thermal images collected during an overflight immediately after the end of Kīlauea summit episode 45 lava fountaining on April 23, 2026.

April 15, 2026—Summary map of tephra fall after episode 44 lava fountaining at the summit of Kīlauea April 15, 2026—Summary map of tephra fall after episode 44 lava fountaining at the summit of Kīlauea

This map shows the tephra fall associated with episode 44 of Kīlauea's episodic summit eruption, on April 9, 2026. Tephra is a generic word for any material erupted by a volcano that travels through the air before landing on the ground.

April 15, 2026—InSAR image of Kīlauea deformation associated with episode 44 of ongoing summit eruption April 15, 2026—InSAR image of Kīlauea deformation associated with episode 44 of ongoing summit eruption

COSMO-SkyMed Second Generation (CSG) interferogram for the period from April 1 to April 9, 2026, covering Kīlauea volcano’s summit region. Each color fringe represents 1.55 centimeters (0.61 inches) of ground movement in the direction between the satellite and the ground (range change).

April 13, 2026—Kīlauea summit eruption reference map April 13, 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.

Seabed maps showing topography, ruggedness, backscatter intensity, sediment mobility, and the distribution of geologic substrates in quadrangle 3 of the Stellwagen Bank National Marine Sanctuary region offshore of Boston, Massachusetts Seabed maps showing topography, ruggedness, backscatter intensity, sediment mobility, and the distribution of geologic substrates in quadrangle 3 of the Stellwagen Bank National Marine Sanctuary region offshore of Boston, Massachusetts

The U.S. Geological Survey, in cooperation with the National Marine Sanctuary Program of the National Oceanic and Atmospheric Administration, has conducted seabed mapping and related research in the Stellwagen Bank National Marine Sanctuary (SBNMS) region since 1993. The area being mapped using geophysical and geological data includes the SBNMS and the surrounding region, which totals
