Cracking and slumping of the Halema‘uma‘u crater walls are clearly evident in this aerial view captured during HVO’s overflight of KÄ«lauea’s summit this morning. Steam plumes have been rising from within the crater, as well as from cracks adjacent to the crater. Photo taken Saturday, June 9, 2018 courtesy of U.S. Geological Survey
USGS-HVO geophysicists installed additional continuous GPS stations around Halema‘uma‘u this morning. These stations will allow scientists to better monitor and measure the ongoing subsidence of Halema‘uma‘u and the adjacent caldera floor.

As of 6:30 a.m. HST today, fissure 8 continued to feed a vigorous channelized lava flow to the east of the vent. Overnight, fountain heights were generally 40–50 m (130-160 ft) high, with occasional bursts up to 60 m (just under 200 ft) high. Fallout from the fountains has built an asymmetric cinder-and-spatter cone around the vent, with the southwest side of the cone slightly higher (about 115 feet) than the northeast side (about 65 feet). This asymmetry reflects the prevailing trade winds, with more lava piling up on the downwind side of the fountains. Photo taken Saturday, June 9, 2018 courtesy of U.S. Geological Survey
An aerial view of the Kapoho ocean entry, as of 6:30 a.m. HST today, shows the extent of the lava delta, now about 200 acres in size, that has formed over the past six days (lava first entered the ocean on the night of June 3). Across the front of the delta, plumes of laze—created by molten lava interacting with seawater—appeared diminished this morning, but was probably due to a change in atmospheric conditions rather than a change in the amount of fissure 8 lava reaching the ocean. Laze, a mixture of seawater steam, hydrochloric acid, and tiny volcanic glass particles, can irritate eyes, lungs, and skin, and should be avoided.

Fissure 8 and lava channel in the lower East Rift Zone of KÄ«lauea Volcano during this afternoon’s overflight, with no apparent slowing in the eruption rate. The lava channel remained incandescent all the way around Kapoho Crater before entering the ocean. Photo taken Saturday, June 9, 2018 courtesy of U.S. Geological Survey
Another aerial view showing prominent cracking around Halema‘uma‘u from the ongoing subsidence at KÄ«lauea’s summit. The steaming cracks in the background have been observed for several days. Photo taken Sunday, June 10, 2018 courtesy of U.S. Geological Survey

Map as of 10:00 a.m. HST, June 9, 2018. The fissure 8 flow has created a lava delta approximately 200 acres in size, filling Kapoho Bay and shallow reefs along the nearby coastline. Given the dynamic nature of KÄ«lauea’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.
This thermal map shows the fissure system and lava flows as of 5:30 pm on Saturday, June 9. The flow from Fissure 8 remains active, with the flow entering the ocean at Kapoho. The black and white area is the extent of the thermal map. Temperature in the thermal image is displayed as gray-scale values, with the brightest pixels indicating the hottest areas. The thermal map was constructed by stitching many overlapping oblique thermal images collected by a handheld thermal camera during a helicopter overflight of the flow field.

This is a Civil Defense Message for 6 a.m., Saturday, June 9, 2018.
Hawaiian Volcano Observatory reports Fissure 8 continues to produce a large channelized flow to the ocean at Kapoho. Sulfur Dioxide emissions remain high from fissure eruptions.
Due to the current volcanic activity, the following is provided for your information:
There is currently no immediate threat, but residents close to the active flow should stay alert to changes in the flow direction and be prepared to voluntarily evacuate with little notice. Heed warnings from Civil Defense officials.
If you feel the effects of sulfur dioxide exposure shelter-in-place or leave the immediate area.
You can monitor sulfur dioxide and hydrogen sulfide on Hawaii Island by visiting the Civil Defense website.
The shelter at Pahoa Community Center is open and pet-friendly. The Keaau Armory shelter has reached capacity.
The Pahoa Post Office is open during normal business hours with temporary Sunday hours from 10 a.m. to 2 p.m. for mail and package distribution only for residents in the affected areas. No retail services on Sunday.
For your safety, heed warnings from Civil Defense officials and stay alert.
Due to the lava entry at the ocean, the following policies are in effect:
Access to the area is prohibited due to the laze hazard.
Stay away from any ocean plume since it can change direction without warning.
The U.S. Coast Guard is actively monitoring the ocean entry area and enforcing a 300-meter standoff zone. Only permitted tour boats are allowed in the area.
Health hazards of laze include lung, eye and skin irritation.
Be aware that the laze plume travels with the wind and can change direction without warning.

Sulfur Dioxide (SO2) and Vog
Click on image for full description of air quality levels.
Volcanic gas emissions remain elevated throughout the area downwind of the vents in lower Puna.
Severe conditions may exist such as choking and inability to breathe.
Sulfur Dioxide (SO2) gas from fissures are especially dangerous for elderly, children/babies and people with respiratory problems.
County, State, and Federal partners continue to monitor the situation. You will be informed of any conditions that affect your safety.
Monitor vog levels and forecasts: People on Hawaii Island outside the area of volcanic activity are also advised to monitor levels of vog at https://vog.ivhhn.org
The residents of Puna are going through a very difficult time. We ask for your help and understanding.
