May 22—Thermal map of fissure system and lava flows

May 22, 2018

 

Thermal map of fissure system and lava flows...
This thermal map shows the fissure system and lava flows as of 06:45 am on Tuesday, May 22. The primary lava flow originates from Fissure 22, but a new flow has been active over the past day from the Fissure 6 area. 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.
