Lava flow reaches Puna Geothermal property

    Lava moves through Leilani Estates on Friday night.

UPDATE: 10 a.m.

The Hawaiian Volcano Observatory reported a new fissure this morning. Fissure 24 is between Kupono and Nohea streets in Leilani Estates. It’s not threatening any structures at this time.

The lava flow that crossed onto the Puna Geothermal Venture property has not impacted any wells. No hydrogen sulfide has been detected.

6:30 a.m.

The Hawaiian Volcano Observatory said a lava flow in Leilani Estates crossed onto the Puna Geothermal Venture property overnight.

No hyrodgen sulfide has been detected as county, state and federal agencies are monitoring levels.

Volcanic gases and vog emissions may increase in areas down wind of the vents. Portions of Kamalii Road are experiencing elevated levels of sulfur dioxide.

SATURDAY, MAY 26

6 p.m.

The lava flow in Leilani Estates has crossed Pohoiki Road slightly north of the HGPA site, the Hawaiian Volcano Observatory reports.

The flows to the south continue to enter the ocean near MacKenzie State Park. Lava is now covering 2,372 acres.

Halemaumau crater is also letting out small bursts of volcanic ash, which is slowly being pushed downwind, southwest into the Kau District.

Volcanic gases, vog and ash emissions may increase in areas down wind of the vents. Areas along Kamalii Road are experiencing elevated levels of sulfur dioxide.

Due to the volcanic activity, ash fallout may cause poor driving conditions. Residents nearby must remain alert to changes in the flow direction, and are advised to prepare for evacuation if their areas become threatened.

PREVIOUS COVERAGE

While Kilauea Volcano continues to pump 10,000 tons of emissions into the sky per day, county officials have now determined that 41 of the 82 structures consumed by lava were homes.

Four explosions from Kilauea crater over night sent ash plumes 12,000 feet above sea level or higher as meteorologists warn that wind patterns could change Monday or Tuesday.

Winds are expected to continue blowing south/south-west into Sunday, said John Bravender of the National Weather Service. But more volcanic eruptions — coupled with changing wind patterns to the north/north-west starting Monday — “will bear watching,” Bravender told reporters today.

“From a vog and S02 (sulfur dioxide) standpoint, this could lead to higher concentrations of gases in more populated places, Pahoa, and other places across the Big Island,” he said.

So far, hot gas coming out of cracks along Highway 130 — the major road leading into Lower Puna — show that levels of hydrogen sulfide are “below the detection limit,” said Wendy Stovall of the Hawaii Volcano Observatory.

The levels indicate that the heat coming out of the cracks “is just steam,” she said.

“Yes, it is hot,” Stovall said. “There is magma beneath those cracks, but it is not close to the surface and it has not breached the water table, as far as we know.”

Evidence of hydrogen sulfide, Stovall said, “means that magma is encountering the ground water and it’s starting to boil away the ground water, which would mean the magma is moving closer to the surface. … But there’s no indication that cracks around Highway 130 are close to showing signs that magma is at, or close to, the surface.”

10:45 a.m.

The U.S. Geological Survey said intermittent ash emissions continue this morning with plumes reaching 12,000 to 13,000 feet. Tradewinds are carrying the ash to the southwest.

USGS also reports fissure 7 increased output overnight.

6:45 a.m.

The U.S. Geological Survey said a series of explosions over 15 minutes this morning produced an ash cloud that rose to 11,000 feet above sea level. The explosions began at 5 a.m. and USGS said the ash cloud data is based on radar data from the National Weather Service.

Meanwhile, a flow in Leilani Estates has slowed its advance and is 150 yards from Road. But lava activity continues in the East Rift Zone as flows continue to enter the ocean near MacKenzie State Park.

Two minor steam explosions were reported at the Kilauea summit over night.

Hawaii County Civil Defense will distribute free masks for ash protection from 9 a.m. to 1 p.m. today at Cooper Center, Hawaiian Ocean View Community Center, Pahala Gym Annex and Naalehu Nutrition Center. Each person may receive up to three masks. Civil Defense said masks do not protect against gasses and vapors and only provide filtering for ash.
