Detailed Description

A comparison of a photograph and a thermal image of an HVO geologist sampling lava from the leading tip of the new breakout that originated near Kahaualeā€˜a. The recently active, but cooling portions of the flow (red and purple areas in upper left portion of image) have average surface temperatures around 300 C (572 F). The actively flowing area in the center of the photograph that the geologist is sampling from (yellow and white colors) has surface temperatures between 600 and 970 C (1100-1800 F). The lava hidden beneath the crust remains well insulated, and previous studies have shown the lava has temperatures around 1140 C (roughly 2000 F).
