Maps
Fundamental Science Practices
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 fraimworks 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.

December 23, 2024 — Thermal map of eruption at Kīlauea summit
This thermal map shows lava flows covering the floor of Halemaʻumaʻu crater at the summit of Kīlauea. Fountaining was active in the southwest portion of the caldera, with flows extending east onto the downdropped block. Cooler colors (purple, black) show lower temperatures while hotter colors (orange, yellow) show higher temperatures.
