This map overlays georegistered mosaics of thermal images collected during a helicopter overflight of Kīlauea’s active East Rift Zone lava flow near Puʻu ʻŌʻō on March 10 at about 10:25 AM. The perimeter of the flow at the time the imagery was acquired is outlined in yellow. Temperature in the thermal image is displayed as gray-scale values, with the brightest pixels indicating the hottest areas (white areas are active breakouts).
