PAHALA, Hawaii (Reuters) – A third lava flow from Hawaii’s erupting Kilauea volcano streamed into the ocean on Thursday as U.S. Marine Corps helicopters stood by to evacuate a Big Island community should molten rock or huge cracks block its final escape route.

Six huge fissures sent rivers of molten rock through a blackened, volcanic wilderness that was once jungle, farmland and rural homes.

Kilauea, one of the world’s most active volcanoes, entered the fourth week of what may be an unprecedented, simultaneous eruption at its summit crater and along a six-mile (9.7-km) string of fissures 25 miles (40 km) down its east flank.

At about 6 p.m. local time on Thursday, the volcano erupted at its summit, sending ash 10,000 feet (3000 m) into the air. The wind may carry ash to the southwest toward the Pahala area, the Hawaiian Volcano Observatory said.

At least 50 rural homes and other structures have been destroyed by lava from fissures in a small area of the Big Island. Some 2,000 people have faced mandatory evacuations and another 2,000 in coastal communities may be forced to leave their homes if State Highway 130, their last exit, becomes blocked.

The U.S. Marine Corps deployed two CH-53E Super Stallion helicopters to Hilo, about 24 miles north (39 miles), in support of a task force standing by in case an air evacuation is needed. Each helicopter can carry up to 50 people at a time.

“We now have the capacity to evacuate all of the estimated population of lower Puna south of the lava flow within a few hours,” Brigadier General Kenneth Hara of the Hawaii National Guard said in a statement.

Road crews dumped material into cracks on the road and covered them with steel plates in an effort to keep the highway open.

“Talks and discussions have been underway for possible air evacuations if it did come to that,” Tim Sakahara, Hawaii Department of Transportation, told reporters in a conference call.

Up at Kilauea’s 4,091-foot (1,246-meter) summit, at least 12 explosions a day on average are pumping ash plumes thousands of feet (meters) into the sky. Ash drifted up to 26 miles (42 km)southwest to dust the black sands of Punaluu beach with gray powder before blowing out to sea.

Down on the east flank of the volcano, six fissures re-erupted in lava fountains, as volcanic activity moved west towards Highway 130.

Geologists said that after three weeks of escalating activity, Kilauea volcano has entered a “steady state” of eruption.

“It’s probably going to do this for a little while longer,” said U.S. Geological Survey scientist Wendy Stovall on the conference call, describing the stage of the eruption as the “middle” or “kind of the steady state.”

While a roughly 10-square-mile (26-sq-km) area of the Puna district has been ravaged, authorities stressed the eruption was having limited effects on the Connecticut-sized island that is a major tourist destination.

Norwegian Cruise Line said it would reinstate port calls to the island’s two largest cities, Kona and Hilo, after cancelling them in recent weeks. Crystal Symphony cruises also said it planned to return to the two ports after cancelling a Wednesday Hilo stop due to “an abundance of caution.”

Hawaii volcano threatens power plant; mass evacuations possible

PAHOA, Hawaii (Reuters) – Hawaii authorities scrambled to move tens of thousands of gallons of highly flammable chemicals from the path of lava on Thursday, and the state’s governor warned mass evacuations might be needed as the Kilauea volcano’s eruption became more violent.

After a new fissure opened on Wednesday about half a mile from a geothermal power plant, Hawaii Governor David Ige set up an emergency task force to remove the pentane used in the plant’s turbines. He cited estimates that if the fluid ignites, the resulting explosion could create a blast radius of up to one mile. (1.6 km)

The Puna Geothermal Venture plant sits at the edge of the Leilani Estates residential area on Hawaii’s Big Island where lava from 15 volcanic fissures has so far destroyed 36 structures, most of them homes, and forced the evacuation of around 2,000 residents.

“As more fissures open and toxic gas exposure increases, the potential of a larger scale evacuation increases,” Ige said in a tweet on Wednesday evening.

“A mass evacuation of the lower Puna District would be beyond current county and state capabilities, and would quickly overwhelm our collective resources,” Ige tweeted, saying in a separate post that he signed a request for federal disaster assistance.

The lower part of the Puna District, of which Leilani Gardens is a part, covers dozens of square miles and is home to many thousands of residents. It has the highest possible hazard risks for lava flows, according to the U.S. Geological Survey.

Exposure to very high levels of the sulfur dioxide gas emitted from the fissures can be life-threatening, experts say.

Geologists warned on Wednesday that Kilauea may be entering a more violent phase of explosive eruptions, the likes of which Hawaii has not seen in nearly a century.

Steam-driven explosive eruptions could hurl “ballistic blocks” weighing several tons upwards of half a mile and dust towns as far away as Hilo, some 25 miles (40 km) distant, with volcanic ash and smog.

Hawaii Volcanoes National Park, where Kilauea is located, said on Wednesday it would close most of the park on Friday due to the threat of a possible explosive eruption.

Magma is draining out of the volcano’s sinking lava pool and flowing underground tens of miles eastward before bursting to the surface on Kilauea’s eastern flank in the lower Puna area.

“There’s still quite a fair bit of magma under the ground that’s available to erupt,” Tina Neal, the scientist in charge of the USGS Hawaiian Volcano Observatory, said in a conference call, adding that she saw no end to activity in the east rift zone.

Kilauea has been in a state of nearly constant eruption for 35 years. It predominantly oozes out lava from fissures that flows into the ocean but occasionally experiences more explosive eruptions, such as an event in 1924.
