May 19—Thermal map of fissure system and lava flows

May 19, 2018

 

Thermal map of fissure system and lava flows...
This thermal map shows the fissure system and lava flows as of 12:15 pm on Saturday, May 19. The two primary lava flows originate from the Fissure 20-22 area, and crossed Pohoiki Road over the past day. The flow front position based on a 6:40 pm update is shown by the red circle. The black and white area is the extent of the thermal map. Temperature in the thermal image is displayed as gray-scale values, with the brightest pixels indicating the hottest areas. 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. The base is a copyrighted color satellite image (used with permission) provided by Digital Globe.
