In September 1982, a new eruption took place within the summit caldera of Kilauea. In the left image, we can see where the lava flow went across the road (which has subsequently been rebuilt). This eruption only lasted for about 19 hours, and produced thin pahoehoe flows such as the one shown at right (this image is located at the tip of the arrow in the left image). The scale bar is divided into 5 cm increments, so that we can see that this part of the flow is less than 30 cm thick. The flow is resting on one of the many boulders that were ejected during the explosive 1924 eruption of Kilauea.
