This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u as of January 2, 2025.

This compilation shows thermal maps of Kīlauea summit eruption for December 23-30, 2024.

This thermal map shows eruptive activity on December 30, 2024, within Halemaʻumaʻu crater at the summit of Kīlauea. Lava fountaining and flows were active in the southwest portion of the caldera. Cooler colors (purple, black) show lower temperatures while hotter colors (orange, yellow) show higher temperatures.

New geologic mapping (Wells and others, 2020b) and geophysical mapping (Blakely and others, 2000; McPhee and others, 2014; Wells and others, 2020a) document kilometers of Cenozoic right-lateral offset along the Gales Creek Fault Zone, a major, northwest-striking fault zone forming the boundary between the Tualatin Valley and the Coast Range. The Bureau of Reclamation’s (Reclamation)...

This map shows recent deformation at Kīlauea over the timeframe of December 17–29, 2024, during which an eruption began within Halemaʻumaʻu crater at the volcano's summit.

IntroductionLocated in the Coast Ranges of northern California, the Bartlett Springs Fault Zone is the easternmost fault in the San Andreas Fault system in northern California. The fault is a right-lateral, strike-slip structure considered capable of producing an earthquake of moment magnitude 7. The purpose of this mapping is to better characterize the geology and earthquake hazards...

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.

This reference map depicts the new Kīlauea summit eruption within Halema‘uma‘u crater on December 23, 2024, constructed using data captured during a USGS Hawaiian Volcano Observatory helicopter overflight at 9:30 a.m.

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...

The southern Stillwater Range in west-central Nevada contains the western part of the Oligocene Stillwater-Clan Alpine caldera complex, which extends about 55 kilometers (km) east from the west side of the Stillwater Range to the northwestern Desatoya Mountains. The complex consists of at least seven nested ignimbrite calderas and subjacent plutonic rocks emplaced into a complex basement...

This map portrays the distribution of landforms along the Umatilla River in northeastern Oregon and covers a corridor 127 kilometers long from the confluence of the Umatilla River with the Columbia River upstream to Meacham Creek. The map encompasses the valley bottom and extends about 1 kilometer up the adjoining hillslopes. Map data are intended to support water quality and fisheries...

This map shows recent deformation at Kīlauea over the timeframe of October 6–18, 2024.
