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.

Geologists at work monitoring Kīlauea's LERZ eruption
Geologist makes early morning observations of the lava fountain and channelized flow at fissure 8 in Leilani Estates.
Kīlauea Volcano — Morning Overflight (June 19, 2018)
Kīlauea LERZ lava flows and fissures, June 19, 1:00 p.m.
Map as of 1:00 p.m. HST, June 19, 2018. Given the dynamic nature of Kīlauea's lower East Rift Zone eruption, with changing vent locations, fissures starting and stopping, and varying rates of lava effusion, map details shown here are accurate as of the date/time noted. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

Geology field crews on the ground near the Kīlauea's fissure 8 midday on June 19, 2018 observed a still-vigorous channelized lava flow being fed by lava fountains at the vent. Standing waves are visible within the channel. Cascades/rapids are visible near the base of the cone, which is an estimated 50 m (164 ft) high. The maximum flow velocity in the channel is 7.7 m/s (17

Kīlauea Volcano — Fissure 8 Lava Channel
Fissure 8 cone, lava fountain, and channelized lava flow on the morning overflight - June 19 at about 6:10am HST. The lava channel is very full with many small overflows visible on the channel margins. Overflows are sluggish and move slowly downslope as they build up the levees.
Kīlauea Volcano — Halema`uma`u Crater (with HVO)
During the helicopter overflight on June 18, crews captured this image of the growing Halema‘uma‘u crater viewed to the southeast. With HVO and Jagger Museum sitting on the caldera rim (right side, middle where the road bends to the left) it is easier to comprehend the scale of

Kīlauea Volcano — Fissure 6
Fissure 6 (photo center) showed signs of activity overnight, producing small amounts of spatter and feeding short lava flows. Fissure 6 is located about 2.2 km (1.4 mi) downrift from Fissure 8.
Kamokuna lava delta: collapse on May 3 and how it looked today
On June 13, 1950, Honolulu was suddenly blanketed by the thickest haze seen since recordkeeping began there in 1906.
Delta at the Kamokuna ocean entry slowly growing
In the first ecosystem-wide study of changing sea depths at five large coral reef tracts in Florida, the Caribbean and Hawai’i, U.S. Geological Survey researchers found the sea floor is eroding in all five places, and the reefs cannot keep pace with sea level rise. As a result, coastal communities protected by the reefs are facing increased risks from storms, waves and erosion.
Ben Gaddis was recently honored by the U.S. Geological Survey for his many years of service as HVO's volunteer photo archivist.
Small delta at the ocean entry
Here are some tips from for essential lava field fashion from the USGS Hawaiian Volcano Observatory geologists who walk miles on Kīlauea lava flows—both new and old.
Small delta has formed at ocean entry; evidence of recent delta collapses
Hawaiian Volcano Observatory (HVO) staff, alumni and friends recently gathered to honor the long and fruitful career of Jeff Sutton, our recently retired colleague.
Small delta at Kamokuna ocean entry
Hawai‘i is not the only island in the United States with an ongoing eruption involving hot lava and cold water.
The ash deposits on the southeastern part of the Island of Hawai‘i have fortuitously presented an agricultural opportunity in an otherwise rocky and hilly landscape. An underappreciated fact is that the explosive nature of our volcanoes provided this opportunity.
