Detailed Description
A blue burning flame of methane gas was observed in the cracks on Kahukai Street, during the overnight hours. When hot lava buries plants and shrubs, methane gas is produced as a byproduct of burning vegetation. Methane gas can seep into subsurface voids and explode when heated, or as shown in this image, emerge from cracks in the ground several feet away from the lava. When ignited, the methane produces a blue flame.
