"The Puna Geothermal Venture had always been contentious on the island, the Associated Press reported, with some native Hawaiians saying that it desecrated Kilauea, where the goddess of fire, Pele, is said to live".
Concerns lava flow could reach nearby geothermal plant; Jeff Paul reports.
Lava from Hawaii's erupting Kilauea volcano is exploding as it pours into the ocean, shooting rock fragments that are a danger to boaters.
This is technically part of the ongoing Kilauea East Rift Zone eruption, which began in 1983.
Metal plugs in the wells, which run as deep as 2,438 metres underground, are an additional stopgap measure.
More than 50 buildings, including dozens of homes, have been destroyed, according to local media.
A spike in the level of gases in the air could lead to a mass evacuation as could a problem at the plant. The plant harnesses heat and steam from the earth's core to spin turbines to generate power.
Lava flows have picked up speed in recent days spattering molten rock that hit a man in the leg the first major injury to occur
Officials earlier this month removed 190,000 litres of stored flammable gas from the site to reduce the chance of explosions.
The occurrence of new lava-spewing vents, now numbering at least 22, have been accompanied by flurries of earthquakes and periodic eruptions of ash, volcanic rock and toxic gases from the volcano's summit crater. It hit him above the ankle. But Kilauea's activity ratcheted up considerably on May 3 after an quake rattled the region; lava began spilling from newly created fissures and spreading through neighborhoods, turning parts of the Big Island into disaster zones. A friend wrapped a sheet around his leg and called for help.
"I don't know if I was in shock", Clinton said.
Doctors say he should be able to walk again, but can't put pressure on his injured leg for the next six weeks.
Kilauea rumbled back to life on May 3 as it began extruding lava and sulfur dioxide emissions through a series of fissures, marking the latest phase of an eruption cycle that has continued almost nonstop for 35 years.
Clinton was the first to suffer a major injury because of the eruption. When lava hits the sea and cools, it breaks apart and sends fragments flying into the air, which could land on boats in the water, said U.S. Geological Survey scientist Wendy Stovall.
Scientists say lava from Kilauea is causing explosions as it enters the ocean, which can look like fireworks.
About 3 miles (4.8 km) to the east of the plant on the coast, noxious clouds of acid fumes, steam and fine glass-like particles billowed into the sky as lava poured into the ocean from two lava flows.
