This telephoto image from January 19, 2017, shows spattering along a down-welling section of Kīlauea Volcano’s summit lava lake. The main area of spattering was about 10 m (32 ft) high, but some lava fragments were thrown even higher. Depending on the lava lake level, spattering on the lava lake surface is sometimes visible from the Jaggar Museum Overlook in Hawaiʻi Volcanoes National Park. USGS photo, M. Patrick
