Active lava delta on south coast of Kīlauea, Hawai‘i

This lava delta at Lae‘apuki added about 24 hectares (60 acres) of new land to the southeast coast of Kīlauea in 2006, but 6.5 hectares (16 acres) slid into the sea in 2007. White plume marks location of lava entering the sea through a tube whose location is shown by blueish fume in middle right. The delta is covered with many recent surface flows (light gray) that escaped from the tube and spilled over the former sea cliff. The white markers inland of the sea cliff were placed by National Park Service to identify viewing areas considered safe from collapse of the delta and sea cliff and large explosions that typically accompany such collapses.
