Unified Interior Regions
Hawaii
The Pacific Region has nine USGS Science Centers in California, Nevada, and Hawaii. The Regional Office, headquartered in Sacramento, provides Center oversight and support, facilitates internal and external collaborations, and works to further USGS strategic science directions.

Hovering Above—UAS’ Role in the 2018 Kīlauea Volcano Eruption Response
The 2018 Kīlauea Volcano eruption marked the first time the federal government used Unmanned Aircraft Systems (UAS) to assist in an eruption response in the United States. The UAS were used to survey areas otherwise inaccessible or too hazardous for field crews or manned aircraft, collect multiple types of data, and provide 24/7 real-time situational awareness at Kīlauea
Hovering Above—UAS’ Role in the 2018 Kīlauea Volcano Eruption (AD)
The 2018 Kīlauea Volcano eruption marked the first time the federal government used Unmanned Aircraft Systems (UAS) to assist in an eruption response in the United States. The UAS were used to survey areas otherwise inaccessible or too hazardous for field crews or manned aircraft, collect multiple types of data, and provide 24/7 real-time situational awareness at Kīlauea
progression of the magmatic intrusion from Kīlauea
Earthquakes (red dots) track the progression of the magmatic intrusion from Kīlauea Volcano's middle East Rift Zone to the lower East Rift Zone between April 30 and May 3, 2018. Orange triangles show the locations of fissure 1 (right), which erupted on May 3, and Pu‘u ‘Ō‘ō (left). The earthquakes shown here are well-located with magnitudes less than 3.5 and depths
...Impact of Future Climate and Non-Natives on HI's Aquatic Ecosystems
A warming climate will have fundamental impacts on freshwater, a critical driver of tropical island ecosystems. Declining baseflows are of particular concern as they threaten to interrupt the link between the freshwater habitats of adult migratory fish and the marine environments where their larvae grow and disperse, especially where habitat availability is already limited
3D model of Pu‘u ‘Ō‘ō's crater
This 3D model of Pu‘u ‘Ō‘ō's crater was created from thermal images during an overflight of the cone. The deepest portion of the crater is about 320 meters (1050 feet) below the crater floor that existed prior to April 30.

panoramic view, Hawai‘i Volcanoes National Park's Crater Rim Drive
In this panoramic view, Hawai‘i Volcanoes National Park's Crater Rim Drive (left foreground) disappears into the enormous void created by the collapse of Halema‘uma‘u and portions of the Kīlauea caldera floor during the dramatic events at the summit of the volcano in May-August 2018.
Kīlauea Summit
The Unmanned Aircraft Systems (UAS) team completed its mission at Kīlauea Volcano's summit, mapping changes within the caldera. Since August 4, 2018, the number of earthquakes at the summit have decreased and the rate of subsidence has stabilized. Sulfur dioxide (SO2) emission rates at the summit is less than 200 tonnes/day, which is lower than at any time since
Close Up of Cone Forming - Kīlauea Lower East Rift Zone
A closer view of the small cone forming on the floor of crater within fissure 8 today (Sept. 5). By this morning, bits of molten lava emitted from the cone every few seconds had built it up to an estimated height of around 3-4 m (about 10-13 ft).
Kīlauea lower East Rift Zone
On September 4-7, the Unmanned Aircraft Systems team flew several missions documenting changes within fissure 8 on Kīlauea's lower East Rift Zone. On September 4, lava erupted on the crater floor within the vent, building a small cone on the floor and creating a flow that did not extend beyond the vent walls. On September 5, gas bursts briefly lifted the crust over a small
Kīlauea Lower East Rift Zone
An Unmanned Aircraft Systems overflight yesterday (September 4, 2018) showed a small cone on the floor of the crater within fissure 8. The cone formed as lava erupted from an opening on the surface of the flow that covers the crater floor.
Low-Level Spatter on New Pad of Lava
During an overflight of fissure 8 this morning, HVO geologists observed low-level spattering on the new pad of lava within the cone. Slow-moving lava had just barely entered the spillway, but was not advancing down the channel.

Activity continues on the 61g flow field and at the ocean entry

Time-lapse sequence shows Halema‘uma‘u gas plume

Kīlauea has now passed the one-year anniversary of the episode 61g lava flow reaching the Pacific Ocean. But what was this busy volcano up to a decade ago?

Kamokuna lava delta subsidence continues

Summit lava lake level continues dropping

Time-lapse sequence of lava delta subsidence at ocean entry

On June 8, 2017, many Island of Hawai‘i residents were awakened by a sharp jolt just past 7 a.m. This natural wake-up call was caused by a magnitude-5.3 earthquake, the largest to strike Hawaii in over a decade.

Weak, scattered breakouts on the coastal plain

Coastal plain flows advance

July 26th marks the one-year anniversary of Kīlauea Volcano's episode 61g lava flow reaching the sea. And at this time, there's no indication that the Kamokuna ocean entry will soon end.

Direct encounters with humans can increase the likelihood that nesting geese will lose their eggs to predators, according to a recent study released Monday, July 17.
