These eerie blue flames are actually burning methane.
The gas can cause underground explosions that can toss hot lava several feet in the air. Accumulations of cooled, hardened lava created a thick, 30-foot (9.14-meter) high wall of solid volcanic rock channeling fresh lava streams from fissures to the south, away from the PGV plant, USGS scientists said.
Blue flames burning in the lava from Hawaii's Kilauea volcano are raising new fears of explosions.
This was just the second time Kauahikaua has seen the blue flames during a volcanic eruption, he also told the AP.
Hawaii County has ordered about 2,000 people to evacuate from Leilani Estates and surrounding neighbourhoods since the eruption began on May 3.
Big Island Now said lava fountains formed from fissures 5, 6, 13 and 19, which feed the lava flow west of fissure 22. Lava has crossed a coastal highway and into the Pacific Ocean, causing a phenomenon known as "laze", and crept towards a geothermal plant in the Puna district.
The volcano produces methane when hot lava buries and burns plants and trees.
Pakistan calls Nawaz Sharif's Mumbai attacks remark 'false, misleading'
Operation Zarb-e-Azb was a joint military offensive conducted by the Pakistan Armed Forces against various militant group in 2014. Nawaz Sharif's name should be place in Exit Control List (ECL) and FIA and NAB should investigate the matter, Khan said.
Residents down rift of the lava flows should be prepared to voluntarily evacuate at a moment's notice.
Civil defense also indicated that the constant eruptions from crack number 22 continue to feed another unsafe lava channel that goes to the ocean.
Officials have also warned residents tobeware of "laze", or lava haze, a toxic gas containing tiny shards of glass which is produced when lava flows collide with the sea.
Despite the epic imagery, Kilauea's recent activity is a blip when compared to its previous episodes since 1983, when the current eruption technically began.
The Kilauea volcano has opened more than 20 vents in the ground that have released lava, sulfur dioxide and steam. One man was seriously injured after being hit by a flying piece of lava.
On Wednesday, large amounts of lava continued to pour from fissures in the central part of the eruption zone from Leilani Estates to Lanipuna Gardens, the latter of which is nearly completely covered by lava.
