HONOLULU (Reuters) - Lava from Hawaii’s erupting Kilauea volcano has covered a potentially explosive well at a geothermal power station and threatened another, after flowing onto the site, officials said.

The Hawaii Civil Defense Agency said the wells “are stable and secure”, and Hawaii Governor David Ige said that the plant was “sufficiently safe” from the lava that has plowed through backyards and streets and burned dozens of homes.

But lava has never engulfed a geothermal plant anywhere in the world and the potential threat is untested, according to the head of the state’s emergency management agency. Local residents fear an explosive emission of deadly hydrogen sulfide and other gases should wells be ruptured.

Over the weekend, there were more than 250 earthquakes at Kilauea’s summit, with four explosions on Saturday sending ash as high as 12,000-15,000 feet, officials said.

Winds are set to shift on Monday and Tuesday, causing higher concentrations of ash and volcanic smog that will spread west and northwest to affect more populated areas, said National Weather Service meteorologist John Bravender.

U.S. Marine Corps and National Guard helicopters are on standby for an air evacuation if fissure activity cuts off Highway 130, the last exit route for up to 1,000 coastal residents.

More residents in some sections of the Leilani Estates neighborhood were ordered to immediately evacuate shortly before 8 p.m. “due to a fast moving lava flow from Fissure 7”, a statement from the civil defense agency said.

Officials had no information on how many residents still remained in the neighborhood or how many people might have already left. Local media has reported that about 2,000 people have already evacuated since the new eruptions began.
