Big Island 2009 - volcanochaser

Closer view of the skylight over the active tube. The very light orange/yellow on the lower right is the flowing lava. The flow is from bottom to top. Darker shades of orange are the glowing walls of the tube. The opening from the side near the top is from a smaller tube which has lost its flow to the larger tube upstream from this location. Surface flows start out as many fingered streams and gradually consolidate into the tube which has the most efficient flow characteristics. Jan 4, 2009
