A helicopter on the floor of the inner caldera of Karkar volcano with the 300-m-high caldera wall behind it. The wall was stripped of vegetation by a powerful phreatic explosion on 8 March, revealing the stratigraphy of lighter-colored lava flows and darker pyroclastic deposits that form the edifice. This location is covered by ash and blocks from the March 8 explosion that occurred one month earlier. Photo by William Melson, 1979 (Smithsonian Institution)
