AP/USGS Volcanic activity at the Kilauea volcano in Hawaii is producing blue fire. The flames are caused by methane gas, a byproduct of the lava being spewed out by the volcano. Authorities warned that build-ups of methane could suddenly explode, hurling rocks around. The flames, which can only be seen well at night, are caused by methane buildups, a by-product of the lava flows which have been enveloping the area around the volcano since it erupted last week on the Big Island. The methane gas is produced when lava rolls over trees and other plant life, and burns it underground, giving off the gas.
