Thermal map of fissure system and lava flows

This thermal map shows the fissure system and lava flows as of 1:15 pm on Monday, May 28. The flow from Fissure 8 that reached Pohoiki Rd. this morning stalled, though activity restarted at Fissure 8 in the afternoon shortly after this map was made. The channelized flows that had reached the ocean were inactive today - a small amount of residual lava was draining from the abandoned eastern channel into the ocean, creating a weak ocean entry plume. Fissure 22 restarted today with lava starting to reoccupy the drained channel. 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.
