This figure compares the photo above with an equivalent view from a thermal camera on August 28, 2014. The plumes of smoke mark the farthest active lava on the surface (small, scattered lobes of pāhoehoe), which are also shown as small hotspots in the thermal image. The pad of lava that emerged from the ground crack earlier this week was inactive at the surface but still quite warm (high temperature patch in center of image). East of this pad of lava, steaming (just below the center of the photograph) has appeared over the past day, suggesting that lava is continuing to advance below the surface along a ground crack. Direct views into the crack were not possible due to thick vegetation, but close views of the steaming areas with the thermal camera reveal temperatures up to 190 C (370 F). These high temperature are further evidence of lava moving through the crack. Photos courtesy of USGS/HVO
