PAHOA, Hawaii — The Kilauea volcano sent more lava into Hawaii communities Friday, a day after forcing more than 1,500 people to flee their rural homes, and authorities detected high levels of sulfur gas that could threaten elderly people and those with breathing problems.
The eruption that began with lava flying into the sky from a crack in a road persisted with reports of molten rock spurting from several volcanic vents. Neighborhoods downhill from the vents were at risk of being covered up. At least two homes were destroyed, officials said.
A huge magnitude-6.9 earthquake has rattled an area near the south part of the volcano, but the Pacific Tsunami Warning Center said there was no threat of a tsunami and transportation officials said no damage to roads has been reported. It came after a magnitude-5.4 earthquake struck the same area Friday.
Julie Woolsey lives on a street where a vent opened up and channeled lava to within 1,000 yards (914 meters) of her house. When it appeared, she freed her chickens, loaded her dogs into her truck and evacuated with her daughter and grandson.
“We knew we were building on an active volcano,” she said, recalling how she purchased the lot on the Big Island for $35,000 more than a decade ago after living on Maui became too expensive. But she thought the danger from lava was a remote possibility.
“You can’t really predict what Pele is going to do,” she said, referring to the Hawaiian volcano goddess. “It’s hard to keep up. We’re hoping our house doesn’t burn down.”
The community of Leilani Estates near the town of Pahoa appeared to be in the greatest danger. Authorities also ordered an evacuation of Lanipuna Gardens, a smaller, more rural subdivision directly to the east. But scientists said new vents could form, and it was impossible to know where.
Civil defense officials cautioned the public about high levels of sulfur dioxide near the volcano and urged vulnerable people to leave immediately. Exposure to the gas can cause irritation or burns, sore throats, runny noses, burning eyes and coughing.
Maija Stenback began to get nervous when she noticed cracks in the streets near her home. On Thursday, she shot video of the lava as it bubbled and splattered across a street about six blocks from her house.
“You can feel it all the way into the core of your being,” she said. “It’s just that roaring and unbelievable power of the lava bubbling up and spitting up into the air.”
Stenback, her daughter and grandchildren packed as much as they could into their car. The two kids were each allowed to select three toys to take before the family left for a friend’s home about a 30-minute drive away.
“I have lived through a lot of lava flows here, but never this close before,” Stenback said.
There were no immediate reports of injuries. At least 100 people were staying in shelters Friday, with many more evacuees believed to be with relatives and friends.
The Hawaii governor activated the National Guard to help with evacuations and provide security for properties that were abandoned when residents fled to safety.
Kilauea has erupted periodically for decades, and scientists said they have no way of predicting how long the eruption will continue.
A key factor will be whether a magma reservoir at the summit starts to drain in response to the eruption, which has not happened yet, said Asta Miklius, a geophysicist with the U.S. Geological Survey’s Hawaiian Volcano Observatory.
“There is quite a bit of magma in the system. . It won’t be just an hours-long eruption probably, but how long it will last will depend on whether the summit magma reservoir gets involved. And so we are watching that very, very closely,” Miklius said.
After a week of earthquakes, authorities had warned residents to be prepared to evacuate because an eruption would give little warning.
Henry Calio said the first sign that something might be wrong happened when cracks emerged in the driveway of his home in Leilani Estates. His wife, Stella, then received a call from an official who told them to get out immediately. They feared they might lose the house.
“This is our retirement dream,” Henry Calio said.
Kilauea’s Puu Oo crater floor began to collapse Monday, triggering the earthquakes and pushing the lava into new underground chambers. The collapse caused magma to push more than 10 miles (16 kilometers) downslope toward the populated southeast coastline of the island.
The magma later crossed under Highway 130, which leads to a popular volcano access point. Authorities closed the area to visitors and ordered private tour companies to stop taking people into the region.
Over the decades, most of Kilauea’s activity has been nonexplosive, but a 1924 eruption spewed ash and 10-ton (9-metric ton) rocks into the sky and killed one person.
A 1983 eruption resulted in lava fountains soaring over 1,500 feet (457 meters) into the sky. Since then, the lava flow has buried dozens of square miles of land and destroyed many homes.
