Detailed Description
This comparison of the normal photograph with a thermal image shows the extent of the lava shield clearly. The lava shield is visible as the area of high temperatures (hot colors) in the thermal image. Corresponding spots are marked with small arrows for reference. The initial channelized flow that reached Pu‘u Kahauale‘a during the first day is inactive now, but still slightly warm.
