Blue flames burning in the lava from Hawaii's Kilauea volcano are raising new fears of explosions. Emergency officials say if fissures open west of Pahoa, lava could block the one remaining open highway.
Blue flames from burning methane are the latest natural phenomena being seen at the eruption of the Kilauea volcano in Hawaii.
Nighttime photos released Wednesday by the U.S. Geological Survey show the flames spouting from cracks in the pavement in the Leilani Estates neighborhood where the volcano has been gushing lava on the big island of Hawaii for the past three weeks.
“The methane gas will flow through the ground, through the cracks that are already existing, and will come up wherever there’s a place for them to come up,” said Wendy Stovall, a scientists with the U.S. Geological Survey.
The methane can seep through cracks several feet away from the lava. It can also cause explosions when it’s ignited while trapped underground. These blasts can toss blocks several feet away, Stovall said.
Hawaii County has ordered about 2,000 people to evacuate from Leilani Estates and surrounding neighborhoods since the eruption began on May 3.
The volcano has opened more than 20 vents in the ground that have released lava, sulfur dioxide and steam. The lava has been pouring down the flank of the volcano and into the ocean miles away.
The eruption has destroyed 50 buildings, including about two dozen homes. One person was seriously injured after being hit by a flying piece of lava.
Lava from that vent was shooting further into the air and producing the highest lava wall of all the vents, which was blocking molten rock from flowing north toward the plant.
Officials shut down Puna Geothermal shortly after the current eruption began.
On Tuesday, officials finished stabilizing wells that bring up hot liquid and steam to feed a turbine generator. A team from the Hawaii Emergency Management Agency and the company continued Wednesday to plug the wells to make sure the fluid inside doesn’t move from one part of the well to the other, said Janet Snyder, a spokeswoman for Hawaii County.
Earlier this month officials removed a flammable gas called pentane from the plant to reduce the chance of explosions.
Tourism officials cheered news that a Norwegian Cruise Lines ship that tours the Hawaiian Islands would resume stopping in Kailua-Kona next week. Businesses catering to tourists on the cruise have taken a hit since the company suspended Big Island port visits after the eruption began.
The company said it would resume calling on Hilo, a town on the eastern side of the island closer to the lava, when conditions allow.
