Hawaii volcano lava crosses on geothermal installation property
Lava from Hawaii’s Kilauea volcano has crossed onto the property of a geothermal power plant, a concern that wells in the plants can be torn.
Lava from the Kilauea volcano covered at least one Sunday in a geothermal power plant on the Big Island, according to a Hawaii County Civil Defense report.
The well was successfully plugged in anticipation of the lava flow, and a second well 100 ft away is also protected, according to the report. The earplugs protect against the release of gas can be toxic when it is mixed with lava.
The lava is an infringement on the property overnight. David Mace, a spokesman for the Federal Emergency Management Agency, said the flow began about 200 metres away from the nearest. But he said security measures went into effect for the fight.

“I think it’s safe to say the authorities are concerned about the lava stream on the plant property since the eruption started,” he said.
Puna Geothermal property-Nevada Ormat Technologies, was shut down shortly after Kilauea began spewing lava on 3 May. The plant harnesses the heat and steam from the Earth’s core to spin turbines to generate electricity. A combustible gas called pentane is used as part of the process, although officials earlier this month removed of 50,000 litres of the gas from the plant to reduce the chance of explosions. Also they covered the 11 wells on the property to prevent a breach.
Before the lava reach, plant spokesman Mike Kaleikini told the news agency Hawaii News Now is that there was no indication of the release of the toxic gas hydrogen sulfide — the greatest fear should be lava hit the pits.
“As long as conditions are safe, we have the personnel on the ground,” Kaleikini said. “First concern is the sulfur dioxide from the eruption and lava come on the site. We monitor for hydrogen sulphide and sulphur dioxide on a continuous basis.”
Steve Brantley, the Hawaiian Volcano Observatory said the flow seemed to have stopped on Sunday morning before he picked up a back-up and covered well on the plant, which is located on the southeast flank of the volcano, located between the residential areas.
Lava-filled fissures have torn pieces of the southeast side of the Big Island over the past three weeks as Kilaeau has become more active.
