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.

Bedrock geologic map of the Woodstock quadrangle, Grafton County, New Hampshire

The bedrock geology of the Woodstock 7.5-minute quadrangle consists of highly deformed metasedimentary rocks of the Central Maine trough, including the Silurian Rangeley and Perry Mountain Formations and the Devonian Littleton Formation. The central, northern, and eastern parts of the quadrangle are underlain by the oldest rocks in the area, the Rangeley Formation. In the southwest and south-centr

Field observations and logs from the Rose Hip trench exposure across a north-facing scarp within the Seattle Fault Zone, southern Bainbridge Island, Washington

The Seattle Fault Zone is an approximately 70-km-long, east-west-trending zone of south-dipping blind reverse faults within the Puget lowland region in Washington. Because of the proximity, the Seattle Fault Zone poses a significant earthquake hazard to the Puget sound and Seattle metropolitan regions. We present preliminary mapping and trench-site information from a paleoseismic investigation acr

Colored shaded relief bathymetry and acoustic backscatter of Ozette Lake, Washington

Offshore of the Pacific Northwest of the United States is the Cascadia Subduction Zone, a 1,000-kilometer-long tectonic boundary defined by a large fault, called a megathrust, that extends from the Mendocino Junction off northern California to the Nootka Fracture Zone off Vancouver Island, Canada (U.S. Geological Survey, 2023). The Juan de Fuca and Gorda oceanic plates to the west of this boundary

June 6, 2024—InSAR image of deformation during Kīlauea Southwest Rift Zone eruption

This map shows recent deformation spanning the recent eruption at Kīlauea.

June 6, 2024 — Kīlauea Southwest Rift Zone eruption

This reference map depicts the June 3, 2024, eruption along Kīlauea's Southwest Rift Zone.

June 4, 2024 — Thermal maps of Kīlauea Southwest Rift Zone eruption

These two thermal maps were constructed from images captured during USGS Hawaiian Volcano Observatory helicopter overflights on June 3, 2024, at 6:00 a.m. HST (left) and June 4, 2024, at 12:00 p.m. HST (right).

June 3, 2024 —Kīlauea Southwest Rift Zone eruption reference map, updated as of 10PM HST

This reference map depicts the location and order of formation of fissure vents that began erupting from Kīlauea Southwest Rift Zone at approximately 12:30 a.m. HST on June 3, 2024.
