The volcano's lava has crept near a geothermal energy plant, risking the release of dangerous fumes. Meanwhile, the fiery flow is already hurting a major tourist stop and the locals who rely on it.
Lava from the Kilauea volcano is pouring into the Pacific Ocean, generating a plume of "laze" — hydrochloric acid and steam with fine glass particles — into the air.
Volcanic rocks 2 feet in diameter have been found in a parking lot a few hundred yards from the volcano's Halemaumau crater, the U.S. Geological Survey reports.
The volcano, which began a period of increased activity earlier this month, is sending ash plumes drifting downwind in what could be a potential threat to aircraft in the area.
The U.S. Geological Survey says that as magma in the volcano drops below the water table, it could create steam pressure and a sudden eruption that would spew toxic gas and "ballistic rocks."
Scientists are closely tracking the eruption at Hawaii's Kilauea volcano. But there's still a lot that they don't know about the eruption — most notably, when it's going to be over.
"This is not the time for sightseeing," the Hawaii County Civil Defense agency says. Some 35 structures have been destroyed by lava from 10 active fissures. Officials are also warning of toxic gases.
More than 1,700 people have evacuated from a neighborhood on Hawaii's Big Island following a volcanic eruption last week. Ground fissures continue to spew lava and gas into residential neighborhoods.
