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 — Halema`uma`u Panoramic
This panorama of Kīlauea's summit caldera was made about 10 a.m. HST from the Keanakāko‘i overlook on the south side of the caldera. Halema‘uma‘u is

Kīlauea Volcano — Documenting Fissure 8 Activity
USGS Hawaiian Volcano Observatory geology field crews maintain watch over the eruptive activity in the lower East Rift Zone and at Kīlauea's summit. Here, a geologist documents the behavior of lava as it exits the Fissure 8 cone. Lava enters the upper channel traveling as fast as 30 km/hour (18 mi/hour).

Kīlauea Volcano — Small Halema`uma`u Eruption (June 24, 2018)
On June 24 a small ash-poor steam plume rose above the Halema‘uma‘u crater rim following another collapse explosion event at 4:12 p.m. HST (image taken at 4:27 p.m.).

Kīlauea summit subsides and produces frequent earthquakes
On June 23, 2018 at 4:32 p.m. HST after approximately 17 hours of elevated seismicity, a collapse explosion occurred at the summit if Kīlauea. The energy released by the event was equivalent to a magnitude 5.3 earthquake. During the intense shaking, rockfalls cascaded down the northern margin of the caldera wall just below Uēkahuna Bluff sending rock dust into the air.

Kīlauea Volcano — Ocean Entry
Lava is entering the sea on the southern side of the entry area primarily through the open channel, but also along a 1 km (0.6 mi) wide area. The entry areas are marked by billowing laze plumes. The interaction of lava with the ocean creates "laze", a corrosive seawater

Kīlauea Volcano — Lava Flows from Fissure 8
View to the southwest, looking "up" the lava channel. Lava flows from Fissure 8 (not pictured) through the open channel about 13 km (8 mi) to the ocean. Lava remains incandescent (glowing orange) along the entire length of the channel with sections of cooled lava (black) on the surface. The dark areas in the lower portion of the image are parts of the early lava flow from

For information about Hawaiian volcanoes, a good place to start is the U.S. Geological Survey (USGS). Between its websites and publications, abundant resources are at your disposal.
Activity continues at the Kamokuna ocean entry and along the 61g flow field
The caldera was a dynamic place during the 300-plus years just before written history began at Kīlauea (in 1823), and the newly defined subdivisions of the Keanakāko‘i Tephra help us understand this energetic and dangerous time better than did the previous terminology.
The USGS Hawaiian Volcano Observatory (HVO) has a long tradition of innovation when it comes to the tools that we use to monitor the status and activity of volcanoes.
Short-lived lava falls at Kamokuna ocean entry
The longest-lived and most voluminous rift-zone eruption of Kīlauea Volcano in more than 500 years—the ongoing Pu‘u ‘Ō‘ō eruption—began in January 1983, and is fast approaching its 35th anniversary.
