VIDEO : Kilauea's Blue Flames Are The Next Big Risk

For the past several weeks, Kilauea volcano on the island of Hawaii (Big Island) has been continuously erupting ? opening dozens of fissures around the volcano and sending lava throughout the area. Now, the latest threat is methane gas. Geological Survey (USGS), blue flames were spotted along road cracks beginning on May 23. The flames are methane gas, a byproduct produced from burning plants and shrubs that are buried under lava. The USGS also warned people about ballistic projectiles shooting out from the volcano.
