Thermal map of flow field

Thermal map of flow field...

Detailed Description

This map is similar to the map above but shows a thermal map over the Episode 61g lava flow. Cooler colors (blue and green) show cooled, inactive portions of the flow surface. Hot colors (red and orange) show areas of active surface breakouts. In some places, the trace of the subsurface lava tube can be seen due to the slightly higher temperatures on the surface (for instance, the tube is visible just upslope of the Kamokuna ocean entry). Areas of the Episode 61g flow not covered by the thermal map are shown as dark gray. The linear boundary in temperatures just upslope of the ocean entry is an artifact due to poor image coverage on the west side of the flow in this area. The thermal map was constructed by stitching many overlapping oblique thermal images collected by a handheld thermal camera during a helicopter overflight of the flow field.
