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.

Kīlauea Volcano — Lavafall Near Kapoho Crater
Near the Kapoho Crater, in the area called Four Corners, the lava channel makes a 90-degree bend. After lava exits the bend, it makes a short drop to form a lavafall. A side channel makes a short surface diversion before rejoining the existing channel.
Kīlauea Volcano — Lava Levees
Lava, from small overflows, cools and congeals along the banks of the lava channel to build lava levees. The levees also build up as moving lava pushes cooled

Kīlauea Volcano — Animation of Summit Subsidence
This animated GIF shows a sequence of radar amplitude images that were acquired by the Agenzia Spaziale Italiana CosmoSkyMed satellite system. The images illustrate changes to the

Kīlauea Volcano — Lava Channel Bend
The lava channel from fissure 8 jumped its banks near Kapoho Crater where the channel makes a 90 degree bend. The flow within the channel was diverted around a constricted area and joined the channel again "downstream" to the south (left).
Kīlauea Volcano — Flows Near Kapoho Ag. and Beach Lots
Near the coast, the northern margin of the flow field is still oozing pasty lava at several points in the area of Kapoho Agricultural and Beach Lots.
Kīlauea Volcano — Sunrise at Haleam`uma`u Crater
Sunrise view of Halema‘uma‘u crater as seen from the USGS observation point from Volcano House in Hawai‘i Volcanoes National Park.
Kīlauea Volcano — Lava Flowing from Fissure 8
Lava within the fissure 8 cone roils and churns where it eupts from the vent and flows rapidly down the well-established channel. This image was captured via a Mavic Pro drone courtesy of the DOI/USGS Unmanned Aircraft Systems team.
Kīlauea Volcano — Fissure 8 at Night
USGS Unmanned Aircraft Systems image of fissure 8 looking east. Below the prominent fissure 8 cone, smaller vents above the original fissure emit volcanic gas. Lava has a brighter glow near the vent exit where it is more turbulent than in the downstream channel, which has portions of darker, cooled crust on its surface.
Kīlauea Volcano — Fissure 8 Flow at Night
During the overnight hours, the UAS (Unoccupied Aircraft Systems) team flew sections of the lower East Rift Zone, monitoring fissure 8 activity and reports of small overflows from the lava channel. This view of fissure 8 and the upper lava channel shows roiling

Kīlauea Volcano — Fissure 8 Lava Flow
Fissure 8 and the upper lava channel, viewed from the early morning helicopter overflight of the lower East Rift Zone. Recent heavy rains have soaked into the still-warm tephra and the moisture rises as steam (right side of lava channel).
Kīlauea Volcano — Evolution of a Blocked Channel (Part 2)
Evolution of a blocked channel, image 2: While observing this area of the fissure 8 lava channel near Kapoho cone during the morning overflight, geologists witnesed an "apartment-building-sized" blockage within the channel give way and be pushed down stream by the pressurized lava behind. The dark portion within the red channel is the freed blockage. Lavacontinues to

Recent breakout is advancing on the coastal plain
With over 1,000 articles on almost every volcano topic imaginable, the Volcano Watch archive is a treasure trove of information on Hawaiian volcanoes.
This week's Volcano Watch is a photo essay featuring notable images from Kīlauea Volcano's two ongoing eruptions: East Rift Zone (Pu‘u ‘Ō‘ō), which began in 1983, and summit (Halema‘uma‘u), which began in 2008.
