This image is a composite of a normal photograph and a thermal image, and shows the currently active flows coming down the pali towards the ocean. The active flow areas are shown as white and yellow, while older, cooler flows are shown by purple hues. The flows this morning were about 900 meters from the County viewing area, at the end of the Kalapana access road.
This thermal image shows the view of the Halema`uma`u vent from today's overflight. The kidney-shaped lava pond, about 90 meters long, is deep within the vent cavity. The mostly-crusted lava migrates from the north (right in this photo), where it upwells from depth, to the south, where is sinks back into the conduit.
Geologist taking a sample from a recently formed skylight on the Quarry flow lava tube. Samples collected directly from the lava tube are usually the best samples for chemical analysis.
Lava flows are once again nearing the County viewing area at the end of Highway 130. The flow front is about one kilometer (0.6 mi) away, burning small patches of vegetation in its path.
