Kīlauea Volcano — Halema‘uma‘u Crater (June 18, 2018)
Halema‘uma‘u viewed toward the west during the June 18 helicopter overflight. HVO and Jaggar Museum can barely be seen on the caldera rim in the upper right of the photograph.

Kīlauea's LERZ
Morning overflight of Kīlauea Volcano's lower East Rift Zone by the Civil Air Patrol provides context for the location of the fissure 8 fountain and lava channel within the lower Puna District. View is to the north. Image courtesy of Civil Air Patrol.
Kīlauea Volcano — Vacationland Laze Plume
Lava enters the ocean entry in the vicinity of Vacationland, producing a vigorous laze plume. Lava flowing into the ocean has built a delta of flows, rock rubble and black sand, which is over 320 acres in size.
Kīlauea Volcano — Halema`uma`u Crater
Inward slumping of the rim and walls of Halema‘uma‘u continues in response to ongoing subsidence at the summit. Sulfur dioxide emissions from the volcano's summit have dropped to levels that are about half those measured prior to the onset of the current episode of eruptive activity. This gas and very minor amounts of

Kīlauea Volcano — Lava Channels
Occasionally, minor amounts of lava briefly spill over the lava channel levees. The spill overs are the shiny gray lobes along the channel margins. The lava flow field has been relatively stable with little change to its size and shape over the past few days. View to the east, with the

Fissure activity and active ocean entry in Kīlauea's LERZ
Fissure 8 produces a lava fountain that pulses to heights of 55 to 60 m (185 to 200 ft). Spattering has built a cinder cone that partially encircles fissure 8, now 51 m (170 ft) tall at its highest point. The steam in the foreground is the result of heavy morning rain falling on warm (not hot) tephra (lava fragments).
Kīlauea Volcano — Vacationland Ocean Entry
View of the active ocean entry in the vicinity of Vacationland. The interaction of hot lava with the ocean creates "laze", a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that can irritate the skin, eyes, and lungs, but that dissipates quickly with distance.
With funding from USGS data rescue initiatives, HVO scanned seismograms from a number of significant earthquakes and seismic sequences. Since last summer, volunteer Marcy Frenz has enthusiastically and diligently assumed scanning duties at HVO, working through the 1974–1984 interval spanning Mauna Loa Volcano's two most recent eruptions.
Delta at the Kamokuna ocean entry slowly growing
On June 13, 1950, Honolulu was suddenly blanketed by the thickest haze seen since recordkeeping began there in 1906.
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.
Hawai‘i is not the only island in the United States with an ongoing eruption involving hot lava and cold water.
Small delta at Kamokuna ocean entry
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.
