HONOLULU (AP) — Scientists in Hawaii have captured rare images of blue flames burning from cracks in the pavement as Kilauea volcano gushes fountains of lava in the background, offering a look at a new dimension in the volcano's weeks-long eruption.
The volcano produces methane when hot lava buries and burns plants and trees. The gas flows through the ground and up through existing cracks.
