## Detailed Description

Why did the lava tube cross the road? This image shows the Peace Day lava tube coming down the pali in Royal Gardens subdivision. The lava tube parallels Alii avenue, shown by the straight line of warm temperatures that represent asphalt heated in the sun. At the intersection of Alii avenue and Paradise street, the lava tube makes a sharp turn west and crosses the intersection, and then turns sharply again downslope (towards the right side of the image). This tube feeds lava to the ocean entry and breakouts on the coastal plain. There is no active lava on the surface in this image - the warm surface temperatures are due to heating by the underlying lava tube. Thermal images such as this help HVO geologists map the lava tube system.
